ATmega32U4 5V/16MHz Pro Micro Leonardo USB Type-C ( Arduino Compatible )

The Pro Micro is similar to the Pro Mini except it uses an ATmega32U4 rather than an ATmega328 microcontroller on board. The USB transceiver inside the 32U4 incorporates USB connectivity on-board and does away with a bulky external USB interface. This tiny micro-controller board does all of the Arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections for Rx and Tx.
