Product description

This module is a microcontroller board based on the ATmega32U4 and is 100% compatible with Arduino Leonardo. It features 20 digital I/O pins (7 of which can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro-USB connection, a power input, an ICSP header, and a reset button.

The ATmega32U4 Leonardo Development Board provides everything needed to get started immediately: simply connect it to a computer via USB or power it with an AC-to-DC adapter or battery.

+ Full compatibility with Arduino Leonardo: The board is 100% compatible with Arduino Leonardo, allowing existing code and libraries to be used without any issues.
+ Suitable for both beginners and advanced users: The ATmega32U4 Leonardo Development Board is easy to program with the Arduino IDE, while also being powerful enough for advanced HID and embedded applications.
+ Good memory capacity: The development board features 32 kB flash memory (with 4 kB used by the bootloader), 2.5 kB SRAM, and 1 kB EEPROM for data storage.
+ USB functionality without an extra chip: Thanks to the ATmega32U4 microcontroller, the board can communicate directly with a computer as a mouse, keyboard, joystick, or MIDI device, without requiring an additional USB-to-serial converter.
+ Low power consumption: The module operates at 5V and can be powered via USB or an external power source (recommended 7-12V).
