Questions
How big is the Control board PCB?
It measures 140 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Control board use?
27 parts, built around the CH340C, ESP32-WROOM-32D, LDL1117S33R and TCA9535PWR(UMW). 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 Control board KiCad files?
From the callumsnowden/matrixstick repository on GitHub, at the commit this page was made from: the board is hardware/control-board/control-board.kicad_pcb and its schematic hardware/control-board/control-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control board design in my own project?
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).
