Welcome, i've got a question that is bugging me for quite some time lately. I've got RaspberryPi zeroW with ZeroCam camera module (without IR filter). To get it to work in dark I bought IR LED modules as seen here:
I know they can be powered by screwing them to dedicated camera, and then the will draw current from CSI interface which is also 3.3v. My question is, can i safely power this IR light modules (or at least one of them) from 3.3v GPIO (1 or 17). My power supply is 2.1A.
Thank you in advance for any clue.
After quite a while of waiting i've received a clue from local reseller. They said that 3W is a power of pair of modules, meaning one of them will be 1.5W
