This voltage will depend on whether you're using a 3.3V/8MHz Pro Micro or a 5V/16MHz version, it'll be either 3.3V or 5V respectively. VCC is the voltage supplied to the on-board ATmega32U4.On the other hand, if the board is powered externally, through this pin, the applied voltage can be up to 12V. If the board is powered via USB, the voltage at this pin will be about 4.8V (USB's 5V minus a schottkey diode drop). RAW is the unregulated voltage input for the Pro Micro.There are a variety of power and power-related nets broken out: Serial Communication - Serial is a great, easy-to-use communication protocol.ĭelving a little further into which pins do what.
