    One more observation. After removing the APU heat pipe, the Switch now glitches with the XIAO. May not be board flex; I placed back the 3 screws that hold the chiller and it still works. Maybe the APU side MOSFET is shorting somehow?

    I'm guessing by front you mean on the back of the MB. Did you solder the source and drain directly to the capacitor? I'm also using 30 Gage wire, but it worked only for a while and now it doesn't.

    So here is summary of my experiments so far: -two transistors, one back and one front, no SDA and SCL: glitch -two transistors, one back and one front, SDA and SCL: glitch -one transistor on back, SDA and SCL: glitch -one transistor on back, SDA and SCL: no glitch -one transistor on front, no...

    Confirmed on the Lite. It works with one transistor directly soldered to the capacitor on the back, but it glitches only with the SDA/SCA lines connected, FW 2.75. This is still with the XIAO, haven put the Waveshare board back yet.

    Thanks again! Now I wonder if I had those incorrectly connected on the original RP2040, though there should be no ambiguity with those I think:

    Thanks rehius, I just saw your replay from yesterday. Never would have guessed what 3 and 4 meant in the guide:D. There are numbers on the back of the XIAO boards next to the pins, so I just assumed the guide was wrongly pointing to overlapping pins.

    Does your custom FW support SDA and SCL on XIAO RP2040? Which pins if it does? The current AIO guide has those wrong as pins 3 and 4.

    I guess I got lucky with just the one and perhaps the SDA and SCL connections were helping too. For a while at least. Unfortunately, no one seems to know where are those on the XIAO. I prefer not to have to touch the MB and the APU if it can be avoided, those ribbon cable connectors are one...

    Thanks, I don't see where it says that. I'll try adding one more transistor on the back and go from there.

    I have Switch Lite. Can the MOSFET be measured through the CPU wire? If I end up replacing it and it turns out it's the cause it could be useful information for future troubleshooting.

    Picofly AIO Thread

    I've read the guide, it cant be pins 3 and 4; those are already used by CPU and D0 on XIAO. I have one MOSFET, installed in this fashion: I see the guide now also provides soldering points for the MOSFET on the back. What's the current preferred method? Still 2 in front, or perhaps 1 front 1...

    Indeed, MOSFET issues is more likely, but replacing the board is much faster and easy. When researching the error I found few reports where replacing the board fixed it. I just wanted to point the error in the guide in case someone knows the correct solder points (if supported on the XIAO at...

    It would seem my RP2040-Zero has stopped working, the Switch (lite) keeps booting into OFW. Apparently that's a thing know. I'm getting the dreaded ==* error, but the MOSFET's are such a pain to get to that I'd rather try a different board first. I don't have a RP2040-Zero, but I have...

    Still though, what does 300Mhz precision do? I'm at 2.73 and the Pico is glitching fine (if a bit slow), so I was wondering if there is any point of updating to 2.74.

    Finally success! It wasn't smooth sailing though. After SDA/SCL not only was I still getting ==* but it also stopped booting into OFW with black screen and not even backlight. Disconnected the SDA/SCL wires and still nothing. While removing them I knocked off the Data0 wire from the resistor on...
