This Pro Micro 5V 16M Mini Leonardo Micro controller?Development Board For Arduino development board has 4 channel 10 bit ADC, 5 PWM pins, 12 DIO, and a hardware serial connection Rx and Tx you are familiar with Running on 16MHz and 5V, this board will remind you a lot of other Arduino compatible boards that you like.
The Micro is a microcontroller board dependent on the ATmega32U4 (datasheet), created related to Adafruit. It has 20 advanced info/yield pins (of which 7 can be utilized as PWM yields and 12 as simple information sources), a 16 MHz gem oscillator, a miniature USB association, an ICSP header, and a reset button. It contains all that expected to help the microcontroller; essentially interface it to a PC with a miniature USB link to begin. It has a structure factor that empowers it to be effectively positioned on a breadboard. The Micro board is like the Arduino Leonardo in that the ATmega32U4 has inherent USB correspondence, killing the requirement for an auxiliary processor. This permits the Micro to appear to an associated PC as a mouse and console, notwithstanding a virtual (CDC) sequential/COM port.
