Pro Micro 5V 16MHz ATmega32U4 Mini Leonardo Compatible Development Board for Arduino | Micro USB

The Pro Micro 5V 16MHz Mini Leonardo Microcontroller Development Board is a compact, high-performance ATmega32U4-based board designed for Arduino enthusiasts and developers. With native USB support and full compatibility with the Arduino IDE, this board is perfect for keyboard, mouse, and serial device emulation, making it ideal for creative electronics, automation, and HID projects.

Running on 5V and 16MHz, the Pro Micro offers 20 digital I/O pins (7 PWM, 12 analog), a micro USB interface, and an onboard voltage regulator that supports input up to 12V DC. Thanks to the ATmega32U4’s built-in USB communication, there’s no need for an external USB-to-serial chip — simplifying programming and enhancing performance.

Built for reliability, the board includes PTC fuse and diode protection, a reset button, and supports auto-reset for uploads. Its small form factor allows easy integration into breadboards and compact enclosures, making it a favorite among makers and hardware developers.
