I'm happy to take a look at it. It does sound like a defective Pi, but I can at least get the setup finished for you so controls will work. Do you sti...

The other USB port doesn't have data pins, so it won't help you. Did you happen to get the microUSB cable in yet? If you can't figure it out, you're w...

It's possible. Did you copy over all the files, including the config.txt? The config.txt file is the one that tells the Pi Zero to switch that pin to ...

I'd like to get more info about what exactly the board was doing. If the HDMI is backfeeding power and keeping the GPIO pins pulled high, then the boa...

Issues with the on/off board, or with the RPi?

Those numbers are exactly what I'd expect. It should be working. Have you tested the composite signal on anything else?

3,3v is what you want, so it's at least working partially. There's one more thing to check. With the board powered on check the voltage at both sides ...

Can you verify that your putting at least 5v into the LCD power input? If it's under 5v then the IC won't function correctly.

You should have contact between all the yellow areas, and you should have contact between all the purple areas. There should also not be a connection...

Do you have an ohmmeter? There are a couple things we can check in the meantime.

Looks like you can get it working by shorting across the diode M7. That will increase the voltage going into the IC enough to get it working at 5v

I can't tell for sure, but it appears that you switched the USB port wires The pic you posted was low resolution, so it was difficult to see where th...

You won't be able to finish the last part of the button setup without the keyboard, so that's why you're stuck. My board isn't really doing anything w...

Are there any numbers on the 8-pin IC at the bottom? Do you have a voltmeter?

I'm not sure what to make of the HDMI issue. The USB connector is routing power to the same parts of the board as those pins. There's going to be a s...

All good, except green. It doesn't go to GND, it goes to the composite pin on the Pi Zero

And green attaches to the composite video source, not GND

That is incorrect. Hopefully you haven't supplied power to it yet. There are 4 pads. The pad above the one you colored red is the one that should actu...

Make sure it's set to 100% by hitting start and increasing it. You can also adjust it more by doing this: You can also modify the board for more volu...

That's what I expect should be the power path, just judging from component placement. Everything red will get the full 5.09v. There are no components ...

Wait, those numbers aren't making sense. That inductor should be connected directly to 5.09v on one side. Is the diode M7 still installed on this one?

I've tested this same type of IC down to 4.9v without issues. It's possible that you're getting a large voltage drop across the first inductor, labele...

That will happen if the joystick isn't wired up, or if it is wired backwards.

That's probably the best thing to try. There's not much that can cause none of the controls to work other than the software not starting on bootup.

Did you copy over the files and run the installer?

Ok this is the standard MP3302-style chip used in most of these boards. It can do 4.75v-28v in and drops it straight to 3.3v. If you put 5v to the bo...

I am trying to find a dtasheet for the AS269 IC. Can you attach 12v to the board and tell me what voltage you get at the pins of the IC, and tell me w...

Can you post a pic of the bottom side of the board?

That covers all the power input. It's definitely doing it's job and dropping voltage to 3.3v for the main IC to use. There's something else going on h...

Are you getting 3.3v on both sides of the inductor labeled 470?

Ok keep it the way it is for now and let's check one more thing. There is an inductor labeled 331 next to the jumper. When you have 5v applied to the ...

Is the other one modified yet? If not, try removing the diode labeled M7 and putting a jumper in it's place.

I have a size limit on images, so that's probably the issue. You can also email them to me at the email address that sent you the order status.

Are you able to post pictures of the wires that attach the batteries to the board? I'm wondering whether you might have them reversed. Also, do you ha...

Ok. I've got you covered. Another one will be headed your way soon.

And can you verify that you have composite attached to this pin (yellow) and only this pin It's just hard to see in the photo.

That's odd. Wiring looks good, so it's probably either the composite on the Pi is having issues, or the LCD or controller is to blame. The easiest way...

Well, that's a new one. There's not much that can go wrong on those. I'd say either the Pi isn't outputting on the composite line (unlikely), somethin...

Use lots of flux too. I had to do the same thing on a test build, and it's not easy. Hopefully you dont destroy the board in the process, but let me k...

Do you have a voltmeter? When you hit the power switch you should be getting 5.2v at the pin circled red, 3.3v at the pin circled orange, and within a...

No, it should just work. 4.06v to the LCD is very strange. Also, the LCD shouldn't function at all with less than 4.5v, so that's confusing me further...

Thanks Assomnia Mustang3027 - Have a look around the site. You'll find most of the information you need. As for touchscreen, it's possible, but the p...

I'm happy to help. Can I get some pics showing the LCD controller and how you've got it wired to the Pi?

Does holding the switch for a few seconds kill power to everything (it should)? If that works then you just need a bit of software to run in the backg...

Ok I was asking about the Zero W because it doesn't automatically pull up the TX pin. A line of code has to be added to config.txt to make it function...

Is that using a Zero W?

I'm very happy you got it working. I definitely welcome feedback on the V3. I plan to use it all for improvements to V4.

The switch only turns off the speakers. If the headphones are working then that at least rules out software causes. It's most likely a short somewhere...

Only the volume buttons are wired and configured, the Home button is not. I'll write some code and post it for you guys once I'm able.

Wow that's a weird one. They must have changed the design in the last couple weeks. Are you able to heat the board a little with a blow drier to peel ...

Nope. Was just making sure it wasn't maybe being caused by a defective on/off board. Ok one last thing to try. Disconnect the wire that goes between ...

You can right-click and save as to download it intact. Notepad might work, but copying the original file is more reliable.

Yeah anything over 2.5v is enough to keep it on. I'm a little baffled. Is this the same board you used on the Pi 2, or did you get two of them and thi...

Does the pin stay at 3.3v the whole time?

Could be lots of things causing it, and the simplest way to rule out most of them is to use a different GPIO pin instead of TX. If you change that 14 ...

You should be getting somewhere around 2.6v on the X and Y pads when the joystick is in the neutral position and the system is powered on. Do you have...

I'm 99.9% sure it's because the joystick either isn't soldered up or is soldered up backward.

When you unplug the power and hit the power button, what LED indications do you get?

Some of the electronics and brackets are needed. I recommend buying a broken from eBay. You can use an aftermarket shell, but you'll still need the in...

Very cool. Thanks for sharing, and thanks for checking out the site.

In v3 the joystick controls are tied to the same GPIO pins as the d-pad. If both the joystick and d-pad doesn't work it's either a bridged/unconnected...

How far did you get?

Cool project. Thanks for posting it.

See if this helps

The config.txt on the v3 page is correct. I'm certain of it. If you copied it to the SD card and overwrite the one that was already there, then it's s...

Gotcha. Feel free to contact me directly so we can work together to get you up and running.

Yeah it'll work. You might need to be creative with the attachment, but it does basically the same job.

There's not really an easy way to make that happen. There are two pads that are used for entering the setup and making those changes, but it requires ...

Not much yet here. Imaged it to an SD card long enough to verify that the config.txt code would work correctly. It boots fast and looks great. Haven't...

Exactly. J+ and - are the power inputs for the joystick.

Bottom left (#1) is ground, middle (#2) is positive (for right headphone), top (#3 or #4) is positive (for left headphone). I can't remember whether i...

The channels operate independently of each other, so that's weird that it only worked with both speakers attached.

The config file must be replaced with mine, otherwise the board will power off within a couple seconds of turning on.

1) Is there a complete wiring diagram on the forum that shows all the hookups to the circuit board? If so all my other question might be answered. Not...

It's implemented now.

No, it's not an emergency or anything. Start and select are used to exit games, so it's good that you're using L and R in place of them. Those are the...
