Rainbowduino LED driver platform - Atmega 328

 It can drive a 8x8 RGB Led Matrix or a 4x4x4 RGB LED Cube in common Anode mode.
Rainbowduino v3.0 uses two MY9221 chips which is a 12-channels (R/G/B x 4) constant current Adaptive Pulse Density Modulation(APDM). Rainbowduino v3.0 has provisions for cascading more such boards with I2C interface.
Rainbowduino v3.0 is flashed with Arduino boot-loader and this makes it easy to program sketches using Arduino IDE. Unlike other LED drivers, this comes with a USB to UART (FT232RL) inbuilt for programming the sketches.
  • Provides 2 x 16 pin header for connecting multiplexed LEDs
  • Constant current(20.8mA) LEDs driver.
  • Can drive 4x4x4 RGB LED Cube or 8x8 RGB LED Matrix (i.e 192 LED)
  • Built in USB to UART chip (FT232RL)
  • Built in 5V / 1 Ampere voltage regulator
  • Can be driven directly via USB cable (No external power adapter needed)
