Description
This Arduino Leonardo-compatible clone is a feature-rich microcontroller board based on the ATmega32u4, offering native USB communication without the need for a separate USB-to-serial chip. Pre-soldered with standard headers, it's ready for easy integration with breadboards and external components. The board provides 20 digital I/O pins (including 7 PWM channels), 12 analog inputs, and can emulate USB devices like a keyboard or mouse—making it ideal for HID projects, interactive designs, and rapid prototyping. Fully compatible with the Arduino IDE, this Leonardo clone delivers powerful functionality at a lower cost.
