Questions
How big is the Sensors+LEDs PCB?
It measures 57.1 × 456.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensors+LEDs use?
41 parts, built around the A3144 and SN74HC165N. 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 Sensors+LEDs KiCad files?
From the aaronluebbert/ChessLink repository on GitHub, at the commit this page was made from: the board is pcb/Microcontroller Lab Summer 2026/Sensors+LEDs/Sensors+LEDs.kicad_pcb and its schematic pcb/Microcontroller Lab Summer 2026/ESP+Power_Only/ESP+Power_Only.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensors+LEDs design in my own project?
Its repository states no licence, so its author keeps all rights: ask aaronluebbert before reusing the design.
