ProMicro 5V 16M Mini Leonardo Microcontroller Development Board

The ProMicro is similar to the ProMini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with a bulky external USB interface. This tiny little board does all of the neat ARDUIN0 tricks that you’re familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 Dios as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite ARDUIN0 -compatible boards but this little guy can go just about anywhere. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin not VCC. This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labelled. We’ve also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuits.
