Arduino Pro Micro Atmega32U4 5V 16MHz
The Pro Micro is a compact microcontroller board based on the ATmega32U4. It features 20 digital I/O pins (7 PWM and 12 analog inputs), a 16 MHz crystal oscillator, and a USB mini-B connector. Its slim form factor makes it breadboard-friendly, ideal for rapid prototyping.
Like the Arduino Leonardo, the ATmega32U4 provides native USB communication, removing the need for an external USB-to-serial converter. This enables the Pro Micro to function not only as a virtual COM port, but also as a keyboard, mouse, or game controller, offering versatile USB device emulation for creative projects.
Please select "Arduino Leonardo" for board & port in Arduino IDE to use it (it has leonardo bootloader inside). Product package doesn't contain any usb cable. Male headers are not soldered.
