While at MOSFETs, those little fellows here seem to be quite capable to handle LED strips (SSM3K324R) - again, PWM at 3.3V logic level. They should be able to handle up to 1A safe and sound in this setup, I guess. Why are spec sheets always guesswork. Just a real nightmare to solder these… guess I finally need to figure out where to order PCBs with parts already assembled :/
Finally found a MOSFET with a small footprint and a low price that seems to be able to easily handle PWM for 12V/6W dimmable LED spots when driven by only 3.3V logic level: AOD424.
I use NRF52840 dev boards, as they have a minuscule power consumption of less than 15mA at 3.3V even with Bluetooth on and discoverable. Sure, not much of a difference when the lights are on; but when the lights are off, and you throw 20 of those onto your offgrid net, it suddenly matters!
