Unless my multimeter is on the fritz, it would seem my 5V Adafruit Trinket is only outputting 3.3V when connected w/ DC power.
When connected via USB, totally fun. Full 5V. But if I disconnect that and connect a 9V wall adapter, the output of the 5V pinout is just giving me 3.3V.
Is that even possible?
I noticed the issue b/c my program wasn't running properly when connected via the DC adapter (but ran just fine via USB). So I tested the voltage and sure enough, 3.3V all around at basically every +/- connection.
