DIY Micro USB to PDMI adapter

I just wanted to share what I'd done for my streak in order to quit carrying a cable around everywhere. This is just a quick outline of what I did and supplies I used to make it.
Disclaimer:I am in no way responsible for your warranty getting void, phone blowing up starting ww3 or any other faults that may be the result of attempting this
Parts list:
1x streak usb cable
http://www.ebay.com/itm/16065922734...NX:IT&_trksid=p3984.m1497.l2649#ht_500wt_1286
1x micro usb to mini usb adapter
http://www.ebay.com/itm/25098693990...X:IT&_trksid=p3984.m1497.l2649#ht_3016wt_1035
1x old dvd case
5 minute epoxy
Optional:
small piece of carbon fiber vinyl
what to do:
-cut micro usb out of its rubber/plastic shell
-desolder all the wires
-cut the streak cable close to pdmi connector
-refer to this site for usb diagram, make sure to note that there's one pin that gets skipped over on the micro usb adapter
http://pinouts.ru/SerialPortsCables/usb_cable_pinout.shtml
-solder wires accordingly refer to my pictures if you get lost (the pdmi cable comes with all the wires correctly color coded)
-plug into streak and see if it works
-if everything works proceed to make a plastic shell for it out of dvd case
-use a little bit of epoxy to mount everything and keep it from sliding around
end result should look something like this

Hi I'm not trying to negate the value of your guide in any way. I think a permanent mod to a compatible connection makes a lot of sense, especially if one never plans on using a Dell Streak 7 dock. However, if you're not that motivated and or aren't willing to brick your device this is a great $8 solution: http://www.ebay.com/itm/140853176551?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649.

The cable you linked to wouldn't work, because the jack on the non-PDMI end is a USB A female connector, which accepts the end of the USB cable (USB A male) that normally plugs into the laptop or PC itself. To make it as useful as the DIY adapter the OP mentioned would require you to dismantle the host adapter and replace the USB A female jack with a MicroUSB B female jack.

PDMI connector to mini usb connector
Hello man. My name is Mario. I come from Italy. I'm a psychologist,but on the spare time I like to play with linux & mobile & tablet & technology in general. I was searching for a OTG adapter that was able to recharge my nexus 10 and at the same time that accepts an external sd card and someone has suggests this to me :
eKit 4 in 1 Data Sync Connection Kit For Samsung Galaxy Tab 2 10.1 & Note 10.1
you can read the full story here :
http://android.stackexchange.com/que...-the-same-time
the problem is that I haven't read very well what he says and I haven't understood that it is not good for the nexus 10. For this reason I have tried to search a way to convert the PDMI connector to a mini usb connector and I have found this thread. I would like to ask you if I can make the same thing that you have done and if you can tell me which electric modification I have to make to the board of this connector to convert it as a mini usb connector. Thanks.

MHL hdmi/vga with OTG & charging cable build

has anyone built an MHL with OTG & charging cable that works yet?
if not I have just received my fully pined 11pin to 6 pin adapter, a working mhl cable, and I'll go start and see how far I get, but if someone knows of one thats done to save the time etc..
what i'd like to know is the full pinout for all 11 pins?
not even found a diagram for this new connector yet showing pin number ordering!

Well I have the mhl/hdmi cable now, let the hacking commence...
https://www.youtube.com/watch?v=2fhBikVZXPg

well the build has stalled for a few days, somehow something went wrong with the tv (psu) and it seems to have 'zapped' my mhl/hdmi adapter....
the adapter communicates with the phone, but i get green garbage on screen.
So to pass the time i took the 11pin micro USB plug apart...
heres how they get 11 pins into a 5 pin hole...

So, considering USB is engineered as a hub design from ground up in the first place, do you think it would be possible to solder an OTG adapter to the 5 pins?

Hopefully this may be of some help, I have also been trying to make one of these for the last few weeks.
So far, from purchasing this MHL - hdmi adapter, I have managed to map most of the pins, but am having difficulties getting USB OTG to work.
Charge, HDMI, and PC data connection work, but i still need to find the USB OTG pins for "smart dock" mode.
I assumed that this would work for USB OTG but it doesn't seem to work for me, it acts as USB Slave not Host (I.e. Connection to PC not HDD/Keyboard)
so far the pins i have identified:
(normal usb part)
Pin 1 - Vcc
Pin 2 - USB - (Slave)
Pin 3 - USB + (Slave)
Pin 4 - Sense (40.2K Ohm)
Pin 5 - Gnd
(extended USB Part)
Pin 6 - ? (Audio/USB host?)
Pin 7 - ? (Audio/USB host?)
Pin 8 - DP (MHL +)
Pin 9 - DN (MHL -)
Pin 10 - MHL ID (connected to ID Pin of MHL Adapter)
Pin 11 - Gnd
I will try and upload some images tomorrow, and a diagram of the plug.

My 11pin mhl cable has a y piece with a usb on one side and hdmi plug on the other. No box like yours.
Do these cables have any components in them?
Is it worth me doing any testing with my cable, what actually activates otg? My son had a low end android tab and there was a menu option to change the usb mode, so how is it triggered on note 2, is it a signal, resistor, or just the presence of a peripheral?
There must be a way of spicing in a otg cable onto an mhl cable.
Smart docks wont be available in uk until march, but I would rather do it by myself with cables anyway.

First of all, sorry i didnt get arount to uplading any images yesterday.
Im in the same boat as you, I didnt think I could get a smart dock, and didnt fancy paying £100 for something I should be able to make for £10. I have since found 2 uk shops that sell them for £60.
On my MHL adaper the socket is built into the body if the device, but it only supplies 5v to the device, no data pins are connected through it unfortunately.
Inside these adapters, there is a chip to convert MHL's 2 data cables into hdmi's ~11 data cables.
On the note2 the modes are activated by a resistor on the sense pin of the USB plug, (pin 4) For smartdock mode, 40.2k ohm resistor is used.
The main problem I am having is acessing the pins, as they are so small on the plug. Im waiting for some copper clad pcb so I can make a breakout board for the usb connector.

Sorry i tried linking to the UK sellers in-case you are interested, but my post count is too low to do so.

OK I have now opened another 5 to 11pin connector, this is the moulded plastic variety...
This is an image of what mine looks like, but i did not use this supplier, i just bought on ebay...

How did you work out which is pin 6? Was it marked etc?

No markings on mine, I just started numbering them as I noted them down (left to right), however i didn't follow standard pin mapping, and think i have noted them in reverse order
The following should be standard numbering. (if Samsung release a spec or diagram of the plug )
Here are the images as promised.
Smart dock pins:
Pin 1 - Vcc
Pin 2 - USB - (Slave)
Pin 3 - USB + (Slave)
Pin 4 - ID/Sense (40.2K Ohm)
Pin 5 - Gnd
Pin 6 - ? (Audio/USB host?)
Pin 7 - ? (Audio/USB host?)

Pin 11 - Gnd

After watching a review of the smart dock, in which the S3 is said that USB doesn't work in dock mode, and along with the Note 2 working with PC Docking. I can only assume that the data has to be on the pins 6 & 7.
The next step is identifying the polarity of them, luckily D+ & D- both can take 3.3v (used as ID for USB 1.0 or 1.1) nothing should be damaged if the polarity is incorrect.
The next issue is connecting all of the wires to the USB pins at once. I can't connect all of the wires to the 0.3mm pins, and expect them to not come loose or short. The only solution that i can think of is to etch a breakout PCB for it. Hopefully it will arrive soon, Unfortunately my first board was way too thick for the plug.

Your attempts look as elegant as mine..
I was trying with a single strand of bare wire, if it goes down fine then it can be insulated with coloured mail varnish.
That way each stand kind of ends if like the varnish covered wire used in transformers or some of those cheap $2 headphones

if you look at 'spare' plugs sold on ebay for the s3, they have the pins setout very odd, for single sided board mounting

Normally when i need to connect to small pins like these, I use Kynar wire, as it is so small and single core. However when usb host didnt work, i assumed that it was because the cable had to much noise, so i changed to normal USB cable (which also didn't work)
The socket is interesting, it looks like they surface mount it, unlike the plug that i have, which mounts on the side of the circuit.
Have you seen anybody selling the plugs cheap, and in low quantities? the only place i can find is alibaba, and i have to buy a few hundred
Excuse the rough edges, I through together a breakout board for the plug, so that i can easily access all of the pins, and secure the cable in place.
I made a quick sketch on a PCB and etched it. Not quite figured out how to print them yet.

I just powered it up, and gave pins 6 & 7 a try with a memory stick connected, unfortunately there was no response from android, it also didn't see a mouse.
not sure why it doesn't detect, maybe there is too much interference, or the pins just aren't usb.
anyway, i will dig out my osciloscope, and start testing the pins to see what data they are trying to send.
I may end up having to purchase the smart dock to see what makes it tick.

i'd check for shorts.
doesnt usb otg need a pin shorted to ground? or 100 ohms etc.

subscribed to this thread and will chime in when I can offer some insight - my smart dock is due to arrive (tomorrow?)
I'll hopefully be taking it apart to test around for what wire is getting what resistance etc...
one thing I'll need to do is make a usb-micro-male end into a usb-a-male end so I can test the dock w/my lapdock (it's been the goal for me on this hdmi/otg/charging build)

Thats the exact same reason that I have been trying to make one.
I have the lapdock ready and waiting to be modified. If you need any info on the lapdock's USB and HDMI connections, have a quick look at "RaspberryPi Lapdock"
I hope that you get your smartdock soon. Im Looking forward to your input.

USB OTG uses a short between pin 4 & 5. The resistance between these pins "informs" the phone about which accessory is connected.
USB OTG mode, will only activate the USB host function, charge and HDMI are disabled in this mode.
Desk Dock mode, enables HDMI, and Charge, but not USB OTG
Smart Dock mode, enables HDMI, charge, and USB OTG.

Important my research on OTG on kindle 8.9HD my fndings

Hi i've been doing some research on why OTG it's not working on this device,
I own a galaxy s4 i9500 and measured pin voltages, on the microusb to USB (OTB cable I got) these are my findings.
USB A pinouts
------------------------
1 VCC +5
2 D-
3 D+
4 GND
Galaxy s4 3.8volts 9.8Wh battery readings
USB female connector (galaxy s4 i9500)
---------------------------------------------
pins 1-4 5 volts VCC while on OTG
pins 1-2 5 volts
pins 1-3 5 volts
USB female connector (kindle fire 8.9hd)
----------------------------------------------
1-4 Nothing
1-2 outputting 1.5 millivolts, bear in mind this is pin 1 vcc and pin 2 D-
1-3 outputting 1.5 millivolts same here pin 1 vcc and pin 3 D+
So that's why we're not getting anything to work out of the kindle with OTG cable, there's no voltage coming out at all. But my doubt is as follows. Would it be possible to bridge the 3.8 volts coming from the battery to pin 1 which should be
5vcc where USB 5 volts should be coming out, in that way we would be having the usb port working fine.
Problem is I don't know if the microusb on this device is propietary and I might redirect the 3.8volts from the battert to pin 1 and when I charge the device everything blows up .. So I would like to hear from you , anyone savvy on in depth electronics or with more background on the matter.

This has been a known issue ever since OTG was introduced for the Original KF. The solution as of now is to either use a powered hub or rig up a powered OTG cable jig.
I'm not sure if it can be fixed at the kernel level, but I'm sure it's being looked at.

I'd be happy with keyboard support like they had with the original KF at this point. 32GB is more than enough for me, so I don't need the extra usb HD space.

So what do you mean I need to inject 5 volts with a usb Y cable and inject 5 volts towards the kindle , I honestly prefer avoid 5 volts from entering the kindle. I prefer to feed up 5 volts line to the device I'm plugging , would that way work? . cause I did download usb diagnostics and it didn't detect a usb host. I'm using 10.1 ROM on kindle 8.9 . Any feedback ?

OTG is disabled in the kernel currently.

Hi hash, thanks for answering, did you disable it ? I'm currently on CM 10.1 is there any chance of enabling it ?. I do really need to use an external storage on my hd kindle. I did those voltage measurements and no voltage is coming out from either pins. I did run a usb diagnostic and no usb host is detected. So again , can you add OTG functionality ? I would be really grateful. Thanks !

It was disabled by Amazon, and I just haven't had the time to debug and re-enable it.

I understand , just take your time . I do really need this functionality. Would we still need external voltage applied for external stoarge to be detected as well as keyboard or gamepads?.

[MOD] PDMI Charger Port to MicroUSB Port Hardware MOD Completed!!

Since it almost impossible to find a PDMI Port, I retrofited a MicroUSB port.
I even contracted FOXXCON, got a reply contract DELL for replacement part.
I have Charging and Data + / - (Detected by PC) working fine.
Only Issue is that the device shows it's not charging when Power ON and connected to PC (Hardware Charging LED is lit).
-Maybe this is Normal??
It does show charging when power on and connected to Charging Adapter.
I will post pictures when I get home today.

Basically Gutted bad PDMI Socket and Shove MicroUSB port in PDMI frame.
Looked up Pin out for PDMI and Micro usb for data +-.

Pogo pins

Hello,
I was wondering what the pinout is for the 7 pogo pins on the side of the RM3(s). I want to 3D-print a holder for the phone, with some extra functionality, just like the Magic Adapter. I can't find a pinout or even what protocol is used to communicate between the phone and the Adapter. Anyone know anything about the pins?

I posted the info a long time ago. You have audio and mic. L,R and Mic, power and gnd, then USB d+ and -. Careful powering stuff off the power and gnd it's not made to power devices. Inside the dock is a 4 port USB 2.0 hub controller not all the ports are hooked up that's how I added a micro SD card reader to my dock.

You can. It's got data + and -
How it works is that goes to a USB hub controller that goes to a USB Ethernet.

The micro SD card adapter I put on one of the unused ports.
