Questions
How big is the Pyro PCB?
It measures 34.5 × 32.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pyro use?
15 parts, built around the IRLML6344TRPBF. 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 Pyro 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 pyro/pyro.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 Pyro design in my own project?
Its repository states no licence, so its author keeps all rights: ask Purdue-Space-Program before reusing the design.
