Hacking Hardware McFly - an RP2040 board compatible with Picofly
@Saliciae I just spotted a different issue with your board, you seem to use microvias or just very small, typical vias. I see also vias in pads. This stuff is very expensive to produce and out of question for hobby boards. Min via drill size for JLCPCB is 0.3mm with 0.6mm diameter. You really...- Tailsy
