This is a MySensors based board that lets you control 4 different pins for analog LEDs. So you can control one RGBW, one RGB, or 4 single color LED stripes. It runs directly of of the 12V DC that also powers the LED strip. IRLM2502 mosefets, an AMS1117 3.3V, an NRF24L01+, an arduino pro mini and some caps are used to control the leds.
