Questions
How big is the Main Module PCB?
It measures 76.2 × 48.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Main Module use?
49 parts, built around the TCAN332GD, W25Q128JVSIQ, ADXL375BCCZ and ESDA7P60-1U1M. 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 Main Module KiCad files?
From the Rowan-Rocketry/SRAD-Avionics repository on GitHub, at the commit this page was made from: the board is Power-Module/pcb/Main-Module.kicad_pcb and its schematic Buck-Converter/pcb/12v-to-5v-Buck-Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Rowan-Rocketry before reusing the design.
