Design a two-layer KiCad PCB entirely from Python scripts - no GUI step, no commercial autorouter
It measures 81 × 56 mm and has 2 copper layers, 1.6 mm thick.
70 parts, built around the TPS5430DDAR, KT-0603R, CL31A226KAHNNNE and CL21B103KBANNNC. 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.
From the GReX-Telescope/PSU repository on GitHub, at the commit this page was made from: the board is GReX_Power.kicad_pcb and its schematic GReX_Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask GReX-Telescope before reusing the design.
