Questions
How big is the Stigma mission board hysteresis PCB?
It measures 60 × 130 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Stigma mission board hysteresis use?
182 parts, built around the MCP2562FD-E/P, LAN8742A-CZ, TPS62933DRL and TPD4E1U06DBV. 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 Stigma mission board hysteresis KiCad files?
From the tudsat-rocket/stigma repository on GitHub, at the commit this page was made from: the board is stigma_mission_board_hyacinth/stigma_mission_board_hysteresis.kicad_pcb and its schematic stigma_breakout_board/stigma_breakout_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stigma mission board hysteresis design in my own project?
Its repository states no licence, so its author keeps all rights: ask tudsat-rocket before reusing the design.
