Adafruit 1455 12-Channel 16-bit PWM LED Driver - SPI Interface - TLC59711

The Adafruit 12-Channel PWM LED Driver has remarkably high resolution PWM, at 16-bits. Ideal if you want precise control of the LED brightness. Each channel can drive 1 or more LEDs in series up to a V+ anode supply of 17V and you can control the current supplied by the constant-current drivers. The solder pads are cleverly laid out so that you can either drive 12 x individual LEDs or you can drive 4 x RGB LEDs and that makes 48-bits of colour. The boards use just 2 x SPI pins which can be chained from one board to another for more ambitious displays.

The board also has a green "power- good" LED, 4 x mounting holes, a 3.3V regulator and a current-set resistor.

Supplied as a fully assembled and tested board with a strip of 0.1in. header pins for you to solder on as required. Adafruit provide a free tutorial and an Arduino library to get you started.
