Hello,
From looking at the Teensy schematics, it appears that for Teensy 3.2 and less, the 500ma fuse comes before the Vusb pin whereas later models put the fuse after the Vusb pin (see diagram). Does this mean that if I have a 2amp USB wall adapter, I should be able to draw more than 500ma (and perhaps the full 2A) with Teensy > 3.2?
I have both new and old Teensy and I want to power my project from USB > 500ma. So is it best to tap into the USB 5V prior to entering the Teensy? (that would at least seem to be true for Teensy <= 3.2 if I understand correctly)
Thanks!
