Questions
How big is the Supercap PCB?
It measures 109 × 155.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Supercap use?
198 parts, built around the RP2040, ADS7822U, MT2492 and TX4139. 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 Supercap KiCad files?
From the Twisted-Fields/acorn-robot-electronics repository on GitHub, at the commit this page was made from: the board is supercap/supercap/supercap.kicad_pcb and its schematic cm4_robot_board/cm4-robot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Supercap design in my own project?
Its repository states no licence, so its author keeps all rights: ask Twisted-Fields before reusing the design.
