The driver for WS2812, SK6812 or similar LED strips controlled via Bluetooth LE. It supports both RGB and WWA LEDs. This driver uses motion and light sensors, so in automatic mode it can turn on the light when it detects someone's presence in the dark. The PCB is designed for the Hammond 1551V3 enclosure, so it can be hung on a wall or ceiling. The firmware for the board is available in Sunmachine-A2-fw repo and the mobile app to control the board is available in Sunmachine-app repo.

Questions
How big is the Sunmachine A2 PCB?
It measures 53 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sunmachine A2 use?
18 parts, built around the SN74LV1T34DBV and LM1117-3.3. 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 Sunmachine A2 KiCad files?
From the gblach/Sunmachine-A2-pcb repository on GitHub, at the commit this page was made from: the board is Sunmachine-A2.kicad_pcb and its schematic Sunmachine-A2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sunmachine A2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask gblach before reusing the design.
