Sunmachine-A3-pcb

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-A3-fw repo and the mobile app to control the board is available in Sunmachine-app repo.
