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)

Hello,
According to the Rainbowduino manual there are eight (8) 500mA LED driver outputs (not common anode), but I can't seem to locate them on the schematic.
Does the v3.0 Rainbowduino support those eight (8) 500mA channels without a common shared anode configuration?
Is it too much to ask for someone to answer this question? The documentation for this product is terrible. This is a useless hunk of nothing if you can't even answer a single question about the purported 500mA high output LED drivers, the entire reason why I bought two of these in the first place.
Is the rainbowduino compatible with your wifi shield? Can I plug it, and use the 8x8 led matrix?
Thanks,
Daniele
Hi Daniele.You can connect Wifi to Rainbowduino via jumper wire(SPI port and digital 2 and 3),and it is feasible to add a led matrix,but it is inconvenient.
I have 5 old V1.2 boards. Can I replace the micro to the ATMega328 version and expect a better V2 compatibility?
Which is the difference between the V.1, V.2 and V.3 serie? (USB interface only?)
Hi.For the first question,maybe you can drop a line to order@seeedstudio.com.And the another one,v1 is the same to v2,but v2 has some differences between v3.v2 can drive a device which voltage can more than 5v,but v3 can't.v3 has a lower occupancy of I/O.More information you can refer to the schematic.
I can't get working my new Rainbowduino v3.0b. Once I plug in the USB just one red LED starts to blink at a rate of about 1Hz. Is this normal? I've spend more than three days to try lot of sketches without any result.
I've also installed the libraries but I can't nether compile the examples due to errors.
Anyone has some advice about how to properly set-up the module?
Thanks in advance.
All the best,
Emanuele

I can't even get my rainbowduino v3 to blink one LED. Where do I get a test code or example code to check that it's functional?

If you are wanting to get the new V3.0 board working with many of the existing pieces of code out there written for 2.0 hardware or prior, good luck. I have invested 2 days trying to get neorainbowduino and mtxcontrol working with no success. If anyone has had success with these two projects with 3.0 hardware, let me know.

Please could explain some of the new features and backward compatibly in Rainbowduino 3, see some from the pictures: analog pins, FTDI, 2.1 jack connector, more visible status and power leds, reset button position.
As always seems great, hope order some soon!

He comprado un rainbowduino V.3. En los primeros momentos funciono con Rainbow Cube. Pero ahora no y el chip Atmega 328 se caliente mucho. ¿es esto normal?
Tocando la placa por atras parpadean algunos leds.

Touching the plate some leds flash back
