Scheme for cable from charging. OTG hub with add. alive or if you have a tablet with one microUSB. What is OTG

Not all old tablets support the function of connecting a flash drive to a modem, but I will tell you how to outsmart and connect a flash drive to them, a modem and a hard drive.

Today I want to introduce your OTG adapter.

First I want to tell you what is OTG? You can connect to your tablet or phone, which supports the OTG function, printer, flash drive and hard drive. Another connection is called USB-host.

You can also connect the keyboard or put it to your gadget, so that the gadget supports this function.

And so, for the creation of this miracle cable, we need:
Old USB pouch
Micro USB socket (distance is possible with a standard USB cable for your device)
Soldering iron and soldering iron

And so, let's go, so that we can get such a cable, we will need to connect the 4th contact from the 5th contact to the micro USB socket

My fault is to reach the fourth contact and connect it with a jumper to the GND wire, as shown in the little

And yet, not everything, to connect to the phone or tablet hard drive, which adapter will not be enough. For connection of attachments, some devices have more than 100mA, and 100mA itself can see the port of your attachment, we need to connect to our OTG cable, additional life, which may be enough to get your hard drive installed.

Axis diagram of such an adapter

Now the hour has come to proceed to the collection
We take an old USB subwoofer and it’s possible to do it not too far from rose 2.0, so the strum is less than 100mA, so that there are no big losses. Vіdrіzaєmo approximately there as shown in the photo

Then we clean our wire

I'm going to solder 4 and 5 pins.

Well, all our cable is at the collection

I just lost the right to reverse the practice, take a tablet, insert the “adapter” and insert it into a new flash drive, everything works about what we should say light, what is blinking, on the flash drive and the tablet is the original flash drive.

Everyone knows that any electronic device can be connected to a computer using a standard USB cable. In this way, for the help of a laptop or a personal computer, you can connect between yourself with various attachments, for example, printers, cameras, smartphones, and attachments for saving data (flash drives and other hard drives).

What is OTG?

What is the best way to do without a computer? A nameless adapter has appeared on the market for a long time under the common name OTG-cable. The number of dollars varies depending on the number of dollars up to a dozen or two. The protection of simple cables on these floorings is insignificant, so you can easily make an OTG cable with your own hands. For example, from the surpluses of old ones and transitions.

Otzhe, it is necessary to understand why we need an OTG cable. Living in another annex for the battery compartment may be needed for the availability of electric power, for example, on trips or hiking trips, but this option is not the most efficient. It’s necessary to decide if we need two specific attachments to be installed between ourselves, or rather, to build a universal OTG cable with your own hands for the installation of any USB attachments, to the store’s kshtalt. Also, it’s easier to see if your device is built to improve the same way.

Instruments and safety equipment

Robots with cables need:

lower for cleaning from insulation;

wire cutters or side cutters (remember the order: "7 times in the air - 1 wind"), soldering on the cable to reduce the quality of the call between the outbuildings and to increase the opir in general, which will be indicated on the cost of data or the impossibility of charging through the conductor's opir;

soldering iron, solder and flux; For example, let's look at the statistics, how you can do without any accessory.

Under an hour of work with a soldering iron, remember to come in safely. This prilad, unsafe with its high temperature, is not only for an hour of work, but also a sprat of hvilin after the winding. Protect the working surface of the table from falling melted tin or rosin. Take care of the shafts of the shkiri in the dot until the parts of the soldering iron are soldered.

What up to what?

The back of the varto is broken, like contacts in plugs and sockets for what you need, for that in the few and micro-options 1 pin more, lower in the roses of the universal serial bus. Also, the first pin is standardly marked with red insulation in the middle of the core, intended for supplying voltage. The other and third pins, marked with white and green insulation, are designated for the transfer of data. The fourth black pin is the price of zero or grounding, which works in a pair with the first wire, which is applied. At the same time, micro-USB has such functions introduced to the fifth, the remaining pin, and the fourth pin is marked as an identifier. Vіn appointments for submission of information about the connection to the attachments and cables of these connections are not connected anywhere.

The simplest option

We can look at the option of setting up two specific outbuildings, for example, a tablet computer and a camera. Shards of insults stench can be nested with 5 contacts, whether micro-or mini-USB, you just need to carefully solder the airborne darts between yourself. Comes with 2 non-required data cables with standard plugs. It is necessary to cut them and clean the darts from the insulation, after which it is good to color differentiation, so black with black, yellow with yellow thin. It is necessary to insulate the skin from others for additional hot-melt adhesive or want to use electrical tape. When such a cable is connected to the extensions, a dialogue menu will appear on the screens, if necessary, you will choose which attachment will be the head of your mini-merezh. You can primus in the cable itself to recognize the head and other row extensions. For this, in the head plug, I will need to connect the 4th and 5th contacts, and in the other plug, the 4th contact simply does not connect to it. In this rank, the extension will automatically designate itself as the lead one at the front, so that the marker contact will show the presence of the front, while on the other extension the wine will be empty.

For various outbuildings

Let's look at the option, how to build a universal OTG cable with your own hands. Cream plug micro-or mini-USB You can take it from old motherboards, plug it into a USB-socket or get a USB-rozgaluzhuvach (so called USB-hub). The remaining option is shorter, to allow the connection to the head extension to the periphery, like to a computer. The sequence of connection is the same, like and more, on the plug I will add the head attachment in a similar rank to the primus, connecting the 4th and 5th pins. On the little ones, you can clearly see the connection diagram of pins at roses and plugs.

From connections to life

Deyakі pristroi vіdrіznyayutsya pіdvishcheni energospozhivannâ, scho prizvodkoї to discharge the battery of the main gadget, smartphone or tablet. On this type of OTG cable, you can do it yourself by adding a live cable with a USB plug for a tie adapter. For which you can remove the excess data cable, for which the micro- or mini-USB plug was earlier installed. Z'ednannya oscillate behind two stream-leading contacts, black and red, ignoring the wires for data transmission. It is necessary to remember that on the great lines of the wire, the settlements with soldered wires, to reduce the voltage and strength of the stream, to that the old winding cables, better for everything, cannot be allowed to reach a stable connection of the outbuildings. Tape about 20-30 cm of the cable for the skin plug and the socket to avoid shaving and interruption.

Nasamkinets want to guess how to pick up an OTG cable with your own hands without a soldering iron. The principle of folding is the same as in the descriptions above, the prote z'ednannya darts are viroblyayutsya in other ways. Let's take a look at two of them here:

Solder paste can be used with powdered solder and flux and does not work with a soldering iron. Such a paste is applied to the parts, which are excited, and fired with a great igniter.

Є z'єdnannya vzagalі without vikoristannya high temperatures. So called scotch-locks - for low-voltage systems with special contact, which cuts into darts behind an additional clamp attachment, pliers, for example.

If you don’t plan to work with your own hands, remember that the cutting of cables is not a guarantee, and such cables are not replaced.

If you have a USB flash drive, you can easily convert it into an OTG-USB storage device, so you can connect it to your smartphone or tablet without the need to carry a USB-OTG adapter with you. You, obviously, can just buy such an attachment in the Internet or shops, but I want to build my own, so it's easy, and I have all the necessary components and the scheme of the OTG cable.

Use risk, save your USB flash drive or smartphone/tablet, be careful when laying and soldering wires, if possible, it will be easier to convert it on a cheap smartphone. I'm ahead of you.

To solder OTG you need:

• Micro USB 2.0 flash drive with soldered socket (no box)
• USB-OTG adapter (may cost less than 100 rubles)
• Multimeter
• Soldering iron
• Basic soldering tips for a multimeter
• Ніж (to open a flash drive)
• Silicone sealant, Sugru (humic plasticine), hot glue or insulation glue
• cutting tool
• Electric drill or dremel with 2mm chisel
• (Out of order) USB socket (tato) type-A for re-pinning

Krok 1: We select the correct USB flash drive

First, what do you need to work, choose a USB flash drive with a soldered rose. Not all USB storage devices are the same and the only way to recognize the price is to discover it. Vykoristovyte for tsgogo nіzh or twist.

[Photo 2-5] - only a Chinese flash drive in a stainless steel case. Like Bachite, this ultra-thin flash drive is stuffed with plastic, there is no soldered rose.

[Photo 6-8] - another flash drive from China. She has a fee for roses, vicoristovuvatimu її. Reveal respect, "brudny" solder at the roses of po'yazaniya z tim, scho I've already soldered this flash drive.

Crook 2: Obrazable USB-OTG adapter

[Photo 1-2] On my model of USB-OTG adapter, I can just slide the frame into the USB port to show you what's in there.

[Photo 3-5] Connect the cable required for the USB storage device. Do not cut the cable over something close to any kind of kіntsіv, we need resentment. Zhovta flash drive just for the butt.

[Photo 6-9] For the help of the cutting tool, carefully cut through and split the inner darts. You need to grind, so that the stench could settle in the middle of the flash drive, if you choose.

Krok 3: Checking the pinout of the OTG adapter

USB-OTG adapters and 4 darts at a time. Two for food, and two for food. You need to reconnect so that you solder the correct wire, otherwise you can donate your smartphone for $500 through the $2 $2 gift project.

Vykoristovuyuchi multimeter and USB-roz'єm (mother), which we have carefully cut, we can pin out the OTG cable. Ring out the colors: red, white, green, black, but don’t start yourself in this order, or maybe you’ll have other colors.

Give respect to the OTG scheme of pinning, as in the photo you see the entrance rose (mother), then the order of colors will be reversed!

[Photo 4-5] I've made a human (external) USB plug to make it easier to check. On the Internet, the cost is less than one hundred rubles.

[Photo 6-7] This is the display of my multimeter, if VIN is in the mode of checking the integrity. Give respect to the correct orientation of wires in that nest. Change the order and go back to the USB splitting scheme for different sums.

Krok 4: Payaemo

Now the time has come to solder the dry. Get your soldering iron and solder ready. Solder all 4 darts.

DOUBLE DOUBLE THERE IS NO SHORT CIRCUIT, not on one of the wires, as if they were soldered together. So change your mind, so that the darts are not close one to one. At the in-line stage, it is impossible to reverse the correctness of the pinout, so you see that you have mercy, then it’s better to be smart, lower the smartphone or tablet.

Krok 5: Get ready and pick up the body

[Photo 1-3] The simplest rock. On the back, you need to drill through the case of the USB stick. You need to make sure that the OTG cable can easily get out of the back of the flash drive. I chose a 2 mm drill, but I think a 3 mm would be better.

[Photo 4-6] Come on, you need to switch over, so that the insides of the flash drives do not move. Shorazu rozkrivayuchi її i zbirayuchi back, є ymovіrnіst, scho kolishna shіlnіst folded perish. That's why I scribbled double-sided adhesive tape, so that nothing collapsed. You can mix Blu-tack, Sugru, hot glue or otherwise.

I also covered the darts with a pink silicone sealant, so as not to worry about those stinks that can stick out one by one and have a short chirp. Robiti tse neobov'yazkovo, but I recommend. I don't know why Sugru is better than Blu-tack for insulating power, but if you have a bag, silicone sealant and hot glue will work.

Krok 6: Axis and everything!

If the robot is finished, let's insert the OTG USB storage device into the computer. The reason I chose the computer through the yaku is those that have more computers on the motherboard and are short-circuited.

Then I'll review the storage device on the tablet via the USB port and OTG. Everything worked wonderfully. For example, I inserted yoga into my android smartphone (LG G4), everything worked wonderfully by itself, it looked like a file manager. Please note that most devices on Android do not support the NTFS file system, so format the USB flash drive in FAT32.

Well axis! Self-sufficient OTG-USB hoarding works! When tsimu vin koshtuvav duzhe cheap!

I want to get ahead of you, if the wires are simple “parallel” wiring, DON’T TRY TO GET OFFENSED KINTSIA ANNEX [PHOTO 7].

[photo 8-10]. Now you know how to store your own OTG-USB storage device. Photo axis of my custom OTG hub. Vіn zrobleny for the help of the same method of sorting out that solder, wind the cable yourself. Vicorist yoga is already more fate without everyday problems.

Maybe a manipulator is connected to the computer for the help of a special usb-cable, which by itself transforms into an attachment for entering information. Does it allow you to create a whole ecosystem with various outbuildings, and even more work, if you need to corny bring the keyboard to your tablet or smartphone?

For this, otg cables are used, as for the fact, adapters between micro-usb and usb are simply chimerically named. Allowing you to connect to the same smartphones, the bears and for the help of an additional software and drivers, you can freely use them, without borders. Such a cable for the arrival of ovnishnіh manіpulyatorіv koshtuє vіd kіlkoh dоlarіv up tо tens, fоrіdіvіd vіd mіrobnіk, а cost і іlkostі іlkostі pristroїv, scho priednuyutsya at a time. І smut food of our inhabitant: how do you grow such an attachment yourself, so that you don’t waste pennies? Fortunately, for whom to finish the old charge, that inappropriate charge, as well as pliers and electrical tape.

As a matter of fact, such attachments cannot be used for everyday folding microcircuits or adapters, all controller adjustments are made for the internal software of the tablet or phone, that’s just a cable with input and output, which can be made for 10 minutes. And yet, how do you make an otg cable with your own hands, how do you have only an old charger for your smartphone? Now, it is necessary to connect external manipulators to mobile devices, and how to fight with power by the force of the extensions? І scho it is necessary to know about otg, persh nizh vikoristati yogo?

Ways to stop

First of all, take a soldering iron to your hands, understand, why do you need such a cable? Even keyboards for the same tablet are specially created and designed for transparency, not seeming about the gamepad and bears. Isn't it a great adapter for the quiet, who can't afford a zoo like this with an outbuilding in the input of information? In fact, there are more universal attachments, even micro-usb zastosovuetsya in the same powerbank, and the phone itself or the tablet with a hard battery becomes a charger for recharging. So, you got into the situation, if the laptop is practically discharged, and the axis of the phone is 100 vіdsotkіv, then you need an otg support.

So, the battery for 2-4 thousand mAh will not last long. Ale, how to go about those, schob terminovo vіdpovіsti on the sheet or praviti the project to the authorities, the account is already trivaє for a second. Until then, the situation is possible and reversible, and for the help of such adapters, you can always charge a friend with a charge of a smartphone. Ale first, take a good look at the old charger, change your mind, you have a soldering iron and a tin. In fact, the same OTG can be called a usb-c - micro-usb cable, which is simply necessary for the masters of new technology from Apple.

How do I know what your attachment is OTG cable

The first axis in front of you is already pinned and soldering iron, but the rest of the point is left to be checked, and why is your building device starting to take off in such a way, how do you allow you to transfer the battery charge? What connects to the new third-party manipulators? Get it every day in the version of android and often in the modules included in the accessories, but to make your life easier, we use anonymous testing programs that allow you to use the phone for these purposes for the treatment of illness. As it was already guessed, as it is not so, try to update the firmware version and get the driver for the necessary accessory and you will be happy.

What tools do you need

Those who did not miss the lessons at the school, already approximately give the necessary tools for folding the cable. We need less to cut the way in and out of the daily exercises and get together with ourselves for help soldering, and then we’ll take some electrical tape, to take it:

1. Shmatochki or pliers, and then we should protect them. Be-yakі zayvі spikes improve the speed of communication between devices, zbіlshyuchi opіr and zmenshuyuchi force strum vіdpovіdno.
2. Lower, or all the same, with pliers, to clean the insulation, moreover, don’t know how to break the line, how to rob the deacons of the mind, to finish a small breeze of a bare dart, so you reduce the chance of breaking the lansyug.
3. Soldering iron. It doesn’t matter if you have a radian attachment in your hands, or you have soldering irons with automatic switching on when torching living matter. Remember the safety rules, trim yoga correctly. With proper legality, you can vikoristovuvat and an attachment for vipaluvannya on wood. Ale, take a few more hours and deprive yourself of the new oxide process.

I know a sprinkling of cunning, to allow you to do without a soldering iron, about like a skin radiant child. To finish the vicorist, whether it be a thread of roasting, or to finish the tovsty midny drіt and rosіrіti yogo okremo, while insulating through direct contact with the shkiroy. And just like that, you can’t wind a soldering iron in your hands, rather, don’t cut it, you can do it with your own hands without the help of a specialist.

Do not forget about those that the device cools down a little bit of fluff after work and try to avoid getting rosin and tin on the steel, especially as wine from combustible materials. Don't worry, for whom you can buy special protective mittens.

Soldering

For the cob, a self-contained cable should be cut after the prepared circuit. Keep the necessary life and do not try to make yoga as long as possible, otherwise you can bring it to incompetence among the victors. If you need to clean up the drіt in the insulation, do not know too much, in this way you increase the stability of the day and change the chance of “breaks” appearing in the joint. That stained glass window is not a trace of a large amount of tin. The more accurate and unremarkable is the charge, the more the transitional capacity and the speed of transferring the charge, and if the power of the struma is reduced to 1 A, then the opir is not up to what.

Having soldered and crossed over to the one who caught the metal, rewind the exposed wires with electrical tape, I’ll do it again - a hundred balls in the same rank are not in line with the design’s construction, there is a trace of unique fanaticism here.

Revising

Having installed all the necessary software and drivers on the phone, try the adapter, if you won’t be able to work - turn the strum for the help of an ammeter. Strumok є? The same problem is already unbearable with smartphones, try testing your self-confidence on a different accessory or a different version of the firmware!
