Pro Micro Development Board Compatible with Arduino 5V 16 Mhz

Arduino Pro Micro Clone 5V 16 Mhz

Arduino Pro Micro has similar features to the Arduino Pro Mini version in terms of physical size, but it has an ATmega32U4 microcontroller integration, which means it also has additional features like USB HID that are available in cards such as Leonardo and Micro. The ATmega32U4 microcontroller has a direct USB connection, so you can program it directly over USB without needing an FTDI card like the Pro Mini.

What Is Arduino ? 

Arduino is an open-source electronics platform based on simple software and hardware. It's designed for people who want to create interactive objects or environments and is used by hobbyists, students, and professional designers to control a variety of devices such as LEDs, motors, sensors, and more. The platform consists of a development board, software, and a community of users sharing their projects and resources. Arduino boards can be programmed using a language based on C++ and can communicate with a computer or other devices through USB or wireless connections.
