Questions
How big is the Ergonomic split left PCB?
It measures 181.7 × 171.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ergonomic split left use?
96 parts, built around the ATMEGA32U4-AU, PCAL9555AHF, SRV05-4 and L01. 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 Ergonomic split left KiCad files?
From the alexBinos/ergonomic_split repository on GitHub, at the commit this page was made from: the board is Hardware/v0/ergonomic_split_left/ergonomic_split_left.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ergonomic split left design in my own project?
Its repository states no licence, so its author keeps all rights: ask alexBinos before reusing the design.
