Here's another data point regarding using the 3V3 line to power a micro-controller as was suggested on another forum. I'm controlling an RGB LED "Neon" strip with a 3V ItsyBitsy...

The output voltage of OUT is 3.3V when on. That's too low to turn on your 5N50 MOSFET (~6VDC). You need a low voltage logic level device. I used an...
