Mini LED Drive Board XL8003

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
