Ok that narrows it down to an issue with the Pi itself or an issue with the OS. Probably not the OS, since you've transferred it the typical way. Can ...

They still output 3.7v (really its 3.0v to 4.2v depending on how charged it is). There's a group of components in the middle of the board that step th...

If you aren't getting 3.3v at the yellow pin, you can connect a wire between the yellow pin and the orange pin to keep the board powered on long enoug...

Ok that rules out the easy things. If you can get that meter then there are some things to test. When you hit the power switch you should be getting ...

Nope, that component won't cause that to happen. That's just a potentiometer that let you set the warning voltage for the low-battery LED. The only t...

Really nice work on that vent. Thanks for posting

Keeping it somewhat on the back burner until I'm caught up on v3 backorders. Integrating the LCD controller will definitely be a huge improvement. Bet...

I'm trying to keep this thread clean. This should have gone into the support thread. Anyway, once you get it working please edit your post and show wh...

The RED and GRN pads connect to GND when they are going to be lit. To get an LED to light, the cathode of the LED would get connected to the RED or GR...

For most of these projects I use 24 or 26 gage for power and 28 or 30 for data/signal.

Which charge module is it?

It's because volume control is not plug and play. Start, select, vol+, and vol- are routed to GPIO pins and can be configured to do anything you like....

Ok that's the problem. Get rid of the teal wires entirely. This should work: Attach the L+ to the center pin of the RCA cable and attach ground to the...

When you say TV, does that mean you're wiring them to the RCA audio inputs on the TV?

Posted by: Natron 5.) This is where my problem happens. If I don't have the ground pin on either side occupied, I get video. If I put the ground wir...

If you're using it for the Version 3, then I recommend leaded solder for the Pi Zero connection. I haven't purchased any in a long time, so I can't re...

Everything looks right with the wiring. Do you get an activity light on the Pi Zero after powering it on? There is an LED on it that blinks as it load...

That rules out damage to the built-in buck converter. So that narrows it down somewhat. Can you post or email some images of your wiring? I want to se...

Now that you've got power going in, check the spot I colored orange before and let me know what voltage you're getting.

The best option would be to scrape away some of the blue color from the board just below the LCD pad. You can see the outline of the trace where it ru...

If you're only getting 1v at the red and black, then something else is going on that has to be fixed first. Those are your power input points. They ge...

Are you getting 5v at the black/red points?

This soldering station has done a great job for me Lead-free solder that works well. It's not as good as leaded, but there's less toxicity. Everythi...

LCD+ on the connection that should be empty could be bad. That's putting 5v directly to the 3.3v chip. Put 5v to the black and red connections, and ...

The pad being lifted off the board shouldn't be an issue. If the connection is broken, then there are multiple other areas that the LCD power can conn...

You could try re-running the button configuration first. It's possible that a button was hit at the wrong time. Try these buttons during the config. ...

I'll still probably update it with the recommendation that people test with the microSD inserted directly into the Pi before soldering the adapter up....

Are all the controls working when you're in the game list, before you actually load a game? If everything worked during the button configuration and t...

I see you posted another question about the controls after posting this. Were you able to resolve the black screen issue? If so, I'm just curious what...

It will, but the diode M7 will cause so much voltage drop that the LCD will either flicker or not work at all. That chip needs over 4.75v to work, and...

You did exactly right by wiring to the converter. The first few that went out (including your's) were built slightly differently. I've moved to a new ...

You will definitely fry the board if you do that.

Oh no we aren't there yet. That will be awful. Disconnect the 9 wires that lead to the SD adapter. Unplug the USB connector USB data connector if it's...

So when you hit the switch you get no change on pin 8? You should be getting at least a momentary jump in voltage. Was this Pi Zero W tested with HDM...

Lol. Just a tad bit. But hey, no spam is getting through. I made some more adjustments, so that might be the last time links get removed. I tend to ag...

Ok I'll test the 4.2 image to make sure that's not the problem. Still try plugging the microSD directly in to rule that out.

Ok. I'm sure it's something simple. So here's what's going on with the shutoff to help with the troubleshooting. The shutoff feature works off of GPIO...

Did you copy the config.txt file and overwrite the one that was on the SD card?

Check this out What you're dealing with is the shutdown feature that kills power if there is no OS running. Are you using the Zero W?

It would work the same way. The retrogame software adafruit made emulateas keyboard presses when you hit a button, and it can be modified to press any...

Excellent. The first place to check would be where the Pi connects to my board, since you're soldering blind. Take the SD card out of the Pi and use a...

If you don't have an OS loaded on the SD card, then it will do that. If you have an OS on the SD card and it's attached to the Pi using a microSD adap...

If you get rid of the diode labeled M7 and connect a jumper in it's place the LCD should work. If it doesn't, then the inductor labeled 101 next to di...

Ok hang tight. I'm going to research a couple things and see whether there are is any way to make your's work without a buck converter.

Can you edit and re-add the links? I'm adding spam filtering software and it's apparently turned up too high.

Excellent. How's the image quality? I'm also curious how much amperage it draws. I've ordered one and can get that information once it arrives if you ...

That's promising. There is a good chance that this will work without any modification. I believe the IC is a variant of the MP2307, so as long as it's...

It's correct. Both boards have 3 GND connections next to each other. For example:

This is what you need: The joystick is designed to work just like pushing a button, so the GPIO pins will see that and Retrogame will issue a keypres...

Almost. Get rid of that blue wire. If you keep it connected then the amp will stay off.

The Pi Zero W is a perfect fit in the Version 3. We've now got Wifi and Bluetooth in the PSPi.

It appears that the RetroPie images aren't working yet.

0.5mm

Check that out. It's an operational amplifier in the emulator. I would use an LM393. The other alternative is the zener and a p-fet, but I couldn't ge...

The fet would have to be in addition to the ones already in the on/off circuit (if you're planning to incorporate it) Also, something just occurred to...

That's exactly the direction I'm pondering on. Using a mosfet that switches off when anything above a certain voltage (4.2v i guess) is supplied to th...

It's probably a leftover from a previous version of the board. Most of the cheap buck converters use a diode in their function. This buck doesn't need...

You might be getting a voltage drop across the inductor. Whats the voltage at the pin2/3 bridge?

Posted by: rutledge.allen.l Calling it a night. No go on this screen. I wired a hot wire to Pin 2 and then tried 3. At 2 I get 0 going past that. On ...

Ok the open RPi USBs complicate it. If you had it broken out then putting the diode on it would probably work. I'm going to ponder on it.

I've considered doing it for my own builds, but I don't see a way to make it a feature in a board I'm selling. The amount of support I'd have to provi...

Yep. At the end of the red line I drew. That whole thick trace appears to be a good connection point. If either of you guys has a 12v power source you...

This is what I'm gathering so far. I drew lines to show the path of the power. I'm still making the assumption that it's dropping to 5v, not 3v. It do...
