An RP2040 based devboard with an Integrated IMU to process tilt and acceleration, This is for outpost and I have journalled everything in my Github

@Naytik on Devboard

This is an Simple RP2040 powered devboard which I designed myself!
I messed the wiring in KiCAD by using 2 almost identical but very different 3.3v nets and did not spot it until I fabricated my board. I fixed it by using a bodge wire to wire the 3.3v pin from the voltage regulator to one of the 3.3v pins on the decoupling capacitors. In the end I think I fried the voltage regulators on both my boards as they were only outputting 1.3v, I ended up hijacking the 3.3v pins on my arduino uno to provide my board with the power is required!

I troubleshooted, assembled and tested the devboard.

When I got my devboard, I realised that it didn’t work because there were 2 3.3v nets and they were not being connected, after linking the 2 3.3v nets together using a bodge wire I realised that the devboard still wasn’t getting enough power as the 3.3v voltage regulator was only outputting 1.3v, I ended up using an Arduno Uno’s 3.3v pins + some jumper cables to provide power to the board.

In the end I was able to make the board work just fine without too many problems!!

here is a picture of the board in the end
