Questions
How big is the FRI ESP32 PCB?
It measures 34.9 × 48.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FRI ESP32 use?
34 parts, built around the ESP32-C3-MINI-1-N4, USBLC6-2SC6, XC6220B331MR and PESD5V0L1ULD. 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 FRI ESP32 KiCad files?
From the bulicp/FRI-ESP32-PCB-workshop repository on GitHub, at the commit this page was made from: the board is 04-rutano/FRI-ESP32.kicad_pcb and its schematic 00-template/FRI-ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FRI ESP32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bulicp before reusing the design.
