Okay so, I'm currently working on a final year project about vein visualization with Raspberry Pi 3 Model B+ and a NoIR camera V2. An infrared light source is required to capture clear vein image. I've tried connecting a 3w IR LED module with adjustable resistor to my camera board by it doesn't seem to work on NoIR V2. So I found an alternative for the IR light source as below. Is there any way that I can power this 24pcs infrared illuminator board using GPIO pins with pulse control through pwm? Thanks!
The specification of this board is as follows:
