SparkFun Pro Micro and Qwiic Pro Micro USB-C

========================================

  

   


   

   

  

  

    
Pro Micro - 3.3V/8MHz 
[DEV-12587]

    
Pro Micro - 5V/16MHz 
[DEV-12640]

    
Qwiic Pro Micro - USB-C (ATmega32U4) 
[DEV-15795]

  


The Pro Micro is a microcontroller with an ATMega32U4 IC on board. The USB transceiver is inside the 32U4, adding USB connectivity on-board without external USB interfaces. The Pro Micro comes in both a 3.3V and 5V version. For users using the Qwiic Pro Micro USB-C, the board includes a jumper to select either 5V or 3.3V, reset button, castellated pads, and Qwiic connector. The USB connector and voltage regulator are also different.
