Day 166 of #PCBs (part 2) - Assembly and testing edition!

And this adapter that lets me mount a Raspberry Pi on a Protonema baseboard fit perfectly the first time:

I added a GPIO pinout reference on the board, since I need to refer to it all the time. It's a little small, but still readable.

The JLCPCB silkscreen resolution has been hit and miss as of late. Some boards come back with really clear, well-defined silkscreen, and others are all blobby.
