Out of curiosity, which SBC? Helios4 / Helios64 by any chance?

One gotcha could be that if some of the specified components aren't available (or, worse yet, EOL'd with no pin-compatible replacement), that could would necessitate more PCB work.

This is coming from someone who is annoyed at ESD441 being out of stock at LCSC and Digikey.

The SBC is called Banana Pi M1+. Thank you for introducing me to Helios (Kobol). Their blog and wiki were a very useful and humbling read.

After I posted my question I learned that BPi didn't open source their PCB layout. It looks like I will need even more help than I originally planned.
