I’d like to turn on a 1 watt LED from my Photon. I’m looking at something like this which takes 3-3.4v and 350mA: https://www.amazon.com/6000K-6500K-300mA-350mA-Intensity-Components-Lighting/dp/B01DBZHR1U
I’ve looked at some 3.3v relays but they’re pretty bulky: https://www.amazon.com/3V-Relay-Module-Optocoupler-Development/dp/B01M0E6SQM
Shouldn’t I be able to do this with a simple MOSFET? Ideally I’d have the same power supply going to my Photon (Lipo battery) switched on through the transistor and to the LED.
If I’m not crazy, any recommendations on transistor part numbers? Maybe even just a 2N2222?
