Questions
How big is the MainBoardV3.2 PCB?
It measures 83.7 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MainBoardV3.2 use?
54 parts, built around the ESP32-S3-DEVKITC-1-N8, TSR 2-2433 and TSR 2-2450. 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 MainBoardV3.2 KiCad files?
From the Unimakers/CDR-2024-ELEC-ROBOT repository on GitHub, at the commit this page was made from: the board is MainBoardV3.2/MainBoardV3.2.kicad_pcb and its schematic MainBoard V4/Logic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainBoardV3.2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Unimakers before reusing the design.
