Questions
How big is the Power board PCB?
It measures 135.8 × 56.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power board use?
87 parts, built around the HC-05, LM324, TCRT5000 and LM393. 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 Power board KiCad files?
From the xtarke/automated_buggy repository on GitHub, at the commit this page was made from: the board is power_board/Hardware.kicad_pcb and its schematic arduino/shield/veiculo_uno.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power board design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
