Questions
How big is the Supra board PCB?
It measures 49.5 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Supra board use?
119 parts, built around the OPA1679ID, W25Q128JVSIQ, MCP4728-E/UN and LD1117S33CTR-HXY. 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 Supra board KiCad files?
From the jsenzel1/supra repository on GitHub, at the commit this page was made from: the board is hardware/board final for public/supra_board.kicad_pcb and its schematic hardware/board final for public/supra_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Supra board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jsenzel1 before reusing the design.
