Arduino Leonardo ATmega32u4 with headers
The Arduino Leonardo is a powerful microcontroller board built around the ATmega32U4 processor, offering integrated USB functionality. This unique feature allows the board to act as a human interface device, such as a mouse or keyboard, directly via USB. It provides 20 digital I/O pins, with 12 capable of analog input, and operates at a 16 MHz clock speed. The board comes ready to use with pre-soldered headers and a power jack, supporting versatile power options through USB or an external adapter. It requires the Arduino IDE version 1.0.1 or later for development.
