Questions
How big is the OpenRider HW PCB?
It measures 94 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenRider HW use?
18 parts, built around the ESP32-WROOM-32UE-N4, SS8050 and INMP441. 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 OpenRider HW KiCad files?
From the Achicken7301/OpenRider repository on GitHub, at the commit this page was made from: the board is schematic/OpenRider_HW/OpenRider_HW.kicad_pcb and its schematic schematic/OpenRider_HW/OpenRider_HW.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenRider HW design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
