Questions
How big is the Mirte master bottom PCB?
It measures 84.3 × 93.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mirte master bottom use?
126 parts, built around the DRV8231DDAR-JSM, DB125-2.54-2P-GN-S, TL431BIDBZR and XL-1615SURUGC. 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 Mirte master bottom KiCad files?
From the mirte-robot/mirte-pcb repository on GitHub, at the commit this page was made from: the board is mirte-master-bottom/mirte-master-bottom.kicad_pcb and its schematic mirte-bms-breakout/mirte-bms-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mirte master bottom design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
