Questions
How big is the BMS 1.1 PCB?
It measures 89.5 × 130 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BMS 1.1 use?
113 parts, built around the SQM120P10_10M1LGE3, ADBMS1818ASWZ, XT90PW-M.G.Y and IPB031N08N5. 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 1.1 KiCad files?
From the Purdue-Space-Program/PSPL_R4_Avionics_Hardware repository on GitHub, at the commit this page was made from: the board is bms/BMS_1.1/BMS_1.1.kicad_pcb and its schematic DAQ_dev_board/DAQ_dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BMS 1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Purdue-Space-Program before reusing the design.
