Questions
How big is the SUB-00156 REV00 PCB?
It measures 113.4 × 73 mm and has 4 copper layers, 1.57 mm thick.
What parts does the SUB-00156 REV00 use?
153 parts, built around the RP2350B, ESP32-C3-MINI-1-N4, SN74LVC1G125DBVR-TP and BME280. 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 SUB-00156 REV00 KiCad files?
From the bcdevices/example-projects repository on GitHub, at the commit this page was made from: the board is bento-board/SUB-00156 REV00.kicad_pcb and its schematic bento-board/Addressable RGB LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SUB-00156 REV00 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bcdevices before reusing the design.
