Hello!

I bought 1 year ago IO Pi Plus to do prototype project.
So in this moment in want to create one own PCB with all used moduls (IO Pi Plus PCB, mosfets module PCB, and other PCB moduls)

So, can i get BOM list of IO Pi Plus PCB or info about:

R1 (R1.2, R1.3, R1.4),
R2 (R2.2, R2.3, R2.4),
R3 (R3.1, R3.2, R3.3, R3.4),
C1 and C2

Thanks in advance

Greetings

Hello Janez

R1, R2 and R3 are 10K resistors.

C1 and C2 are 100nF capacitors.

I have updated the schematic for the IO Pi Plus to include the values for the resistors and capacitors. You can download the new version from schematic-iopiplus-2-1.pdf
