Adafruit 16-Channel 12-bit PWM/Servo Driver and CREE-leds

Post by johellin »

Hello.
I am fairly new to the subject of electronics, but I was wondering if the board mentioned in the title would be able to drive 4 single or even 4 pairs (8 total) of Cree X-Lamp XM-L RGBW led's. Any suggestions to what powersupply I would need?

Data on the Cree XM-L can be found here:

High powered LEDs like that (350mA per color) require a high-powered driver capable of delivering those currents. For LED drivers that accept PWM dimming control, the 16-channel 12-bit driver can still be used to control the brightness.

First of all, thank you for a very quick reply!
Do you have any driver boards (or combinations) that are capable of delivering such currents?

We do not. To drive those RGB leds, you would need something like a set of 3 of the 350mA Buck Pucks. Some of the Buck Puck models can be dimmed via a 5v TTL PWM signal:
