The Espruino Pico has two pins that seem to output voltage: V_out seems to output 4.8V, and 3.3 seems to output 3.3V (big surprise). What is the 4.8V for, and if I have a 5V or 3.3V tolerant device, can I power it off of either of these pins (connecting ground pin to - of course)?
Also, it isn't entirely clear to me, and I don't think I can safely test this with a multimeter like the above, but what is V_IN for? Does it need to be a steady voltage or would a battery work?
