The Rainbowduino board (V3.0) is an Arduino compatible controller board with professional multiplexed LED driver. 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.


Features

  • 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).

    yes , it can be cascaded , but you need to write the code yourself case we don't have the cascade library for Rainbowduino version 3.0 .

    Yes , it can be connected to a 3 column by 2 row display , it need to write the code.Using 12V can work ,but the board will be hot,suggest to using 9V.And if you want to use extent power ,you need to jump Drive to Vin in the back of board.

    Hi! Thanks for your reply. In the datasheet is written that a resistor Rex-A/B/C of 2,34 kOhm should produce an output current of 25 mA. Therefore the 2,8 kOhm resistors on the rainbowduino should produce a constant current of about 20 mA. According to

    Datasheet mentions Output capability up to 60mA,
    where might damage appear, would there be a workaround for 60mA ?
    V2 Rainbow supported even up to 120mA.
