Software for High Scorers 2026 RoboCup Junior team
Motor controller pcb is an open-source printed circuit board by debater-coder, from the debater-coder/robocup-26 repository on GitHub, published under the MIT licence. It is a 2-layer board of 117.1 × 126.9 mm with 30 parts on 63 nets, routed with 344 tracks and 11 vias.
Its parts include 12 connectors, 4 capacitors, 3 ICs, 1 switch and 1 fuse. It belongs with the robots and motor control boards and the RP2040 boards of this library.
This is the monorepo for the High Scorers RoboCup Junior Opens Soccer team. When browsing code,
it is highly recommended to browse in an editor with "Go to definition" support. If you are viewing from
GitHub, press the . key to open in an online VSCode instance.

The 26 most common of 30 parts.
It measures 117.1 × 126.9 mm and has 2 copper layers, 1.6 mm thick.
30 parts. 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 debater-coder/robocup-26 repository on GitHub, at the commit this page was made from: the board is motor-controller-pcb/motor-controller-pcb.kicad_pcb and its schematic motor-controller-pcb/motor-controller-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
