Questions
How big is the SC-002 RGB 2layer BLE PCB?
It measures 22.6 × 29 mm and has 2 copper layers, 0.99 mm thick.
What parts does the SC-002 RGB 2layer BLE use?
52 parts, built around the CH570D, TP4055, WS2812B and CJBA3139K-TP. 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 SC-002 RGB 2layer BLE KiCad files?
From the Subjective-Reality-Labs/SC-002 repository on GitHub, at the commit this page was made from: the board is hardware/SC-002_RGB_2layer_BLE/SC-002_RGB_2layer_BLE.kicad_pcb and its schematic hardware/SC-002-C/rev1/SC-002_simple_single_color.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SC-002 RGB 2layer BLE design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
