DESCRIPTION
The Pro Micro 3.3V/8MHz is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interfaces.
This tiny little board does all of the neat Arduino 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 8MHz and 3.3V, this board will remind you a lot of your other favourite Arduino-compatible boards but this little guy can go just about anywhere.
This is the 3.3V version so, as always, keep in mind the limits of system voltage. The lower system voltage also has its advantages, though, like the ease of use with many common 3.3V sensors. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the ‘RAW’ pin, not VCC.
