New to developing on the Electron. When it is plugged in with USB is the VIN pin automatically outputting 5V when running? Or do I need to set a pinMode for it?
Vin is not a GPIO but a hard wired connection with a Schottky diode for protection against backfeeding.
Ahh i see, so when USB is plugged in and battery is charged, VIN will output 5V
Even without the battery being full or even attached Vin will output 5V (Vusb - 0.2V to be exact).
