Questions
How big is the Nff pcb PCB?
It measures 91 × 53.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nff pcb use?
184 parts, built around the A33, CH340C, RTL8723DS-CG and AP3036BKTR-G1. 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 Nff pcb KiCad files?
From the o7-machinehum/flipper-blackhat repository on GitHub, at the commit this page was made from: the board is hat/nff_pcb/hardware.kicad_pcb and its schematic hat/nff_pcb/a33_power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nff pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask o7-machinehum before reusing the design.
