Pico Computer 3 – New production run (V3.3?)

Hi Peter, hi everyone,

I'm planning another production run of the Pico Computer 3, with a minimum quantity of 15 boards.

I've noticed that your GitHub repository now contains versions 3.2 and 3.3 in addition to 3.1.

According to the README, V3.2 uses a different USB host power controller, while V3.3 also improves the thermal connection of the 1.3V regulator.

Before placing the order with JLCPCB, I'd like to ask:

Peter, would you recommend using V3.3 for a new production run? Has this revision already been built and tested successfully?

I'm planning to use the following files:

- PicoComputer3.3.zip
- PicoComputer3.3BOM.xlsx
- PicoComputer3.3CPL.xlsx

Thanks in advance!

Best regards,
Manfred

Added question: What's abot the placement of RMC2. It looks faulty.

I've built 3.3 and it works perfectly, the keyboard version also uses the same circuit as 3.3. JLC don't have a 3d model for the RMC but the board will be fine.

Can someone link me to the v3.3 files.
I was not aware of progression from v3.1, so for the next lot of boards that I order, I would like to be sure I also am using the v3.3 boards.

I think Peter has them up on Github, but I forget the link....

At the bottom of https://github.com/UKTailwind/Pico-Computer-3 file list there are a couple for v3.3.
Perhaps the readme file has the info you need.
