Questions
How big is the Workcross ReverseCam PCB?
It measures 112 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Workcross ReverseCam use?
71 parts, built around the ESP32-S3-WROOM-1-N8, TJA1051T, DS18B20 and LM1117MPX-3.3. 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 Workcross ReverseCam KiCad files?
From the db8fs/Workcross-ReverseCam repository on GitHub, at the commit this page was made from: the board is hardware/pcb/project/Workcross-ReverseCam.kicad_pcb and its schematic hardware/pcb/project/RGB_LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Workcross ReverseCam design in my own project?
Its repository publishes it under the GPL-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).
