ITead mystery PCB: High-power RGB LED driver

Posted on Thursday, January 12th, 2012 in PCBs by DP

Schazamp received a few mystery PCBs from Itead’s open PCB service. He contacted the designer of the PCB and got more info about this board, as well as the schematic.

It’s a controller for driving two 3 watt RGB leds in series, you need 6 pin RGB leds for this, you can also use it to drive a single common cathode led.

A custom arduino bootloader has to be written into the atmega8..

We love the “If you can read this, you forgot the heatsinks.” comment added to the silkscreen.

Via the forum.
