Questions
How big is the 101 PCB PCB?
It measures 68.6 × 53.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 101 PCB use?
89 parts, built around the ESP32-WROOM-32, ARDUINO UNO R3, DRV8837DSGR-MS and LSM6DS3. 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 101 PCB KiCad files?
From the ICRS/101 repository on GitHub, at the commit this page was made from: the board is 2023/101 Devkit Board/PCB/101 PCB/101 PCB.kicad_pcb and its schematic 2023/101 Devkit Board/PCB/101 PCB/101 PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 101 PCB design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
