    I bought a breadboard power supply and the options to feed it power are a barrel jack and usb-a. Considering the size of the thing mini or micro would have made way more sense.

      The ones I have go trough the onboard voltage regulator and you can use them to power USB-devices. I suppose they’ve skipped diodes and other protective components so it can feed back to the circuit, but I haven’t tested that.
