Questions
How big is the Ff power pcb PCB?
It measures 60 × 37 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ff power pcb use?
60 parts, built around the PBO-5C-5, AP131-25WG and SMBJ7.0A. 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 Ff power pcb KiCad files?
From the o7-machinehum/wifiwart repository on GitHub, at the commit this page was made from: the board is electronics/ff_power_pcb/hardware.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ff power pcb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
