This RGB driver module can control independently 3 LEDs or a single RGB LED. With the use of PWM, the RGB LED can be controlled to produce many custom color combinations such as orange, soft red, green and more.

Specifications

  • On-board power LED and reset button
  • Working Voltage Range: 3.3 V to 5 V
  • All pins have been routed out for direct connection to microcontroller
  • PCB Size: 37.2 x 22.5 mm

Communication Protocol

  • Setup the UART communication baud rate at 9600 bps
  • Send the initialization byte 0x1F
  • Send the channel number (1: red, 2: green, 3: blue)
  • Send the brightness value (0 - 100%)
  • Send the checksum (the sum of the first 3 data bytes)

For example, for setting the red LED brightness to 1%, you would have to send the following byte sequence: 1F 01 01 21

For setting the brightness of the blue LED to 50%, you would have to send the following byte sequence: 1F 02 32 53

For setting the blue LED brightness to 99% you would have to send the following byte sequence: 1F 03 63 85
