BTLED-01
Bluetooth-enabled RGB LED driver
An open-hardware PWM driver board for 12V RGB LEDS, specifically 5050 LED strip.
Features an onboard Arduino Nano and HC-05 Bluetooth module for control.
Designed to handle up to 6A current draw, roughly equivalent to 100 5050 LEDs at full brightness on all channels.
Project files are for Autodesk EAGLE.
