Questions
How big is the Sbcb PCB?
It measures 72.5 × 85.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sbcb use?
112 parts, built around the ESP32-S3-WROOM-1-N8, DRV8311HRRWR, AP2112K-3.3 and ICM-42670-P. 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 Sbcb KiCad files?
From the jaguilar/sbcb repository on GitHub, at the commit this page was made from: the board is kicad/main_board/board.kicad_pcb and its schematic kicad/drv8304_eval/_restore_backup_2026-07-09T09-03-53-901/drv8304_eval.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sbcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaguilar before reusing the design.
