Questions
How big is the Board eng PCB?
It measures 53.3 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board eng use?
15 parts, built around the L293D and WS2812B. 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 Board eng KiCad files?
From the egoraura/jun-eng repository on GitHub, at the commit this page was made from: the board is board-eng/board-eng.kicad_pcb and its schematic board-eng/board-eng.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board eng design in my own project?
Its repository states no licence, so its author keeps all rights: ask egoraura before reusing the design.
