Diode solder pad

Totally fixable. You’re in the right place 👍 Mind starting a thread and adding a picture?

This is when it s plugged directly into

This is when it's plugged directly into USB right, not into TRRS? I haven't seen that before. You could try clearing the EEPROM and flashing the default firmware.

Debugging

Probably doesn’t help you now, but I would have checked in and asked for help before you desoldered the MCU. It’s hard to desolder the MCU and it’s possible you damaged a pad or trace. What MCU did you build with? When you plug in the board, does the MCU get warm near the USB connector?...

Keyboard help

Feel free to start a thread and send pictures of the top and bottom soldering as well, and I can take a look 👍

intermittent bongo on snap 75 with 1 oled

Hey! It might be an oddity of only having one OLED, but I’m not positive. Do you mind snapping a quick video so we can see what it’s doing? I haven’t tested with only one OLED but I can do that later today and see if it matches how your board is acting.

Reset debugging

Update, along with that, it compulsively connects and disconnects, when connected i can reflash it but it does not work sometimes due to it just disconnecting midway

TRRS troubleshooting

Which firmware do you have on the tidbit? I would look and see if you can figure out why your LEDs are going dim. That seems like a clue. The boards should behave and look exactly the same when connected over TRRS as they do when connected with USB. If one/both are going dim, something might not be right.

Big LED troubleshooting

I gotcha! This is viewed from the bottom of the board. You want to connect to the bottom side of the resistors as shown.

Scratched Traces

Correct! I can show you which traces should be connect to which IC pins if that’s helpful as well.

Zxcv row issues

Sadly a whole row on my nibble no longer works, zxcv ect. This was my first build so it is probably something wrong with soldering. I have checked the diode layout for the layer and then the mcu pinouts so I can check for colds but I'm a bit lost. I am using iso layout so the \ key works since it isn't apart of that row. but all of 3,0 to 3,15 isn't working
