Description Can drive up to 1A, 42V, for example: 3x parallel x 12x serial x 1W LEDs. or 12x serial x 3W LEDs. Specifications: Input voltage support 3.6V~36V, 12V is most recommended. But also can use lithium 4.2V battery (no more than 10W @ 4V). You can find test images here. Notice connect load first, then supply power on, the board can be destroyed if no load when powered up. Output Setup: Default drive current is: 0.22V / 0.34R (two parallel 0.68R) = 0.647A. If remove one resistor, output current is 0.22V / 0.68R=0.32A Reserved through-hole resistor soldering place, you can add setup resistor if you need
