Questions
How big is the Hardware 2 PCB?
It measures 85.4 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hardware 2 use?
77 parts, built around the LMV358, LM2596S-5.0, AMS1117-3.3 and DW01A. 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 Hardware 2 KiCad files?
From the lev-dec/mode_bike repository on GitHub, at the commit this page was made from: the board is PCB/Hardware_2.kicad_pcb and its schematic PCB/Hardware_2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hardware 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lev-dec before reusing the design.
