Questions
How big is the BMS Teidesat PCB?
It measures 90.2 × 95.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BMS Teidesat use?
93 parts, built around the TMS5703137DPGEQQ1, AD8606ARMZ-REEL, AD8605ACBZ-REEL7 and ACS37002LMCATR-050B5. 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 BMS Teidesat KiCad files?
From the Teidesat/PCB-BMS repository on GitHub, at the commit this page was made from: the board is BMS_Teidesat/BMS_Teidesat.kicad_pcb and its schematic BMS_Teidesat/BMS_Teidesat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BMS Teidesat design in my own project?
Its repository states no licence, so its author keeps all rights: ask Teidesat before reusing the design.
