Raspberry Pi RP2350 based PCB design

19 Jun 2025

Sometimes back, I was designing a PCB based on RP2350 and now I received the finished PCB. So this post is about the experience that I would like to share about my PCB design.

Firstly, the original plan of creating this PCB was to create RP2350 based Single Pair Ethernet development board. For that I had used ADIN-1111 chip. Unfortunately, it was not available during the PCBA making. Hence the original idea was not possible. But I have tested the RP2350 chip and it is working fine.  The design is based on KiCAD and is 4-layer design.

The easiest idea to test this board is to use Micropython so that the board can be tested fast. I tested a simple blink program on this board and it works fine.

    Very nice. Does your SPE board include PoDL (power over data lines)? That's a design challenge just on it's own. I've always fancied the microchip SPE ICEs over ADIN-1111, purely on price. I see Arduino…

    Thank you.!

    PoDL is interesting a topic, but I still have to gather skills for that.

    Awesome build! Infact I was also working on something similar with PoDL.

    Would need either a fancy IR re-work tool or bottom heat and very careful use of hot air gun on the top. If unleaded solder on main board its very hard not to get the chip too hot without expensive tools.

    But I agree there is enough solder there to not need paste at all.
