Questions
How big is the Akimbo PCB?
It measures 163.9 × 125.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Akimbo use?
79 parts, built around the ATMEGA32U4. 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 Akimbo KiCad files?
From the rkanati/akimbo repository on GitHub, at the commit this page was made from: the board is akimbo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Akimbo design in my own project?
Its repository states no licence, so its author keeps all rights: ask rkanati before reusing the design.
