TECNOIOT 2pcs Pro Micro ATmega32U4 5 V/16MHz Module with Pin Header for arduino Leonardo

x2pcs Pro Micro for Arduino ATmega32U4 5V/16MHz Module With 2 Row Pin Header Description: The Micro is a microcontroller board based on the ATmega32u4, developed in conjunction with Adafruit. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro is similar to the Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.
