i have been trying to find a way to drive some leds for my build that i could afford but would like not to have to gather the componets and build one. you can find it on the ebay using this search phrase
Arduino 6 channel led shield 3 currents can be set 0,35-0,7-1A
has anyone used or have any idea if this would work for driving three strings of 12 3w high power leds i will be using a meanwell powersupply as well as using jardunio to interface with it.
It would probably work, but it's only rated to 30V, so you won't be able to drive 12 leds per string. More like 9-10 at the most.
