ATmega32U4 3.3V 8Mhz Pro Micro USB 5V 16MHz Board Module For Arduino/Leonardo ATMega 32U4 Controller Pro-Micro Replace Pro

Arduino compatible microcontroller running at 5V/16MHz. Similar to the Pro Mini except with an ATmega32U4 on board. 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs. Voltage regulator on board. The Pro Micro 5V/16MHz Arduino Compatible Microcontroller 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 interface.
