Aampheo·Jan 7How to make a shield for Arduino Nano in KiCad?Here’s a practical way to design an Arduino Nano “shield” (a carrier board that the Nano plugs into) in KiCad. The key idea is: don’t copy the Nano PCB shape—just place two 15-pin headers at the right spacing, plus any extras (VIN/USB clearance, moun...3 min read·ampheoelectronic.hashnode.dev
