2026-06-24 (W) SubdermalDuino Getting ready for a homemade board

The first print for my board should not be a fully manufactured PCB, since I can easily test for errors by making one at home. Soldering an MDBT50Q-1MV2 module may be tricky, but I only need to get a few critical pins welded to test the circuit. I made a copy of my previous design, removed the LEDs, and made the board rectangular. I used auto-routing to make a single-layer board. The first version had very narrow gaps and would likely lead to shorts with my homemade setup. I made a second version with double-wide clearances, but that required a couple of jumpers. I do not mind the jumpers in this proof-of-concept design since I will only make one. I also converted the components to IMT to make installation easy. I printed the circuit on sticker paper. These were from old shipping labels. I ordered some blank copper boards, and it was a good thing I did not have them immediately because I forgot to mirror my prints.

I forgot to mirror these before printing
