Questions
How big is the Kbd nes v2 PCB?
It measures 51.1 × 40.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Kbd nes v2 use?
53 parts, built around the RP2040, W25Q128JVSIQ, AMS1117-3.3 and TPS2553DBVR-1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Kbd nes v2 KiCad files?
From the bchelf/keyboard-nes repository on GitHub, at the commit this page was made from: the board is hardware/kbd-nes-v2/kbd-nes-v2.kicad_pcb and its schematic hardware/kbd-nes-v1/kbd-nes-v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kbd nes v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bchelf before reusing the design.
