KEYESTUDIO ATmega32U4 leonardo R3 development board +1M Micro USB Cable For DIY Project

The Keyestudio Leonardo R3 is an ATmega32U4-based development board designed for open-source electronics and DIY projects. It is an ideal choice for students, educators, and makers who want to build interactive devices that can interface directly with computers. This versatile microcontroller comes complete with a 1-metre micro USB cable to get you started immediately.

Built-in USB communication

The ATmega32u4 microcontroller features integrated USB communication, eliminating the need for a secondary processor. This allows the board to appear as a native keyboard or mouse when connected to a computer.

Versatile input and output pins

With 20 digital input/output pins, 7 PWM outputs, and 12 analogue inputs, this board offers extensive connectivity for sensors and actuators. A 16 MHz crystal oscillator provides reliable timing for your projects.

Flexible power options

The board can be powered via the micro USB connection, an external DC power jack (7-12V), or through the Vin and GND female headers (7-12V). This allows for easy integration into both stationary and mobile battery-powered projects.

Dual-purpose ICSP header

The In-Circuit Serial Programming header is designed to program firmware directly onto the ATmega32u4 chip. It also doubles as an SPI communication interface for connecting compatible modules.

Convenient hardware features

An onboard reset button allows you to quickly restart your code during testing and debugging. The package also includes a 1-metre micro USB cable for hassle-free connection to your PC.

Software and tutorial support

The board is fully compatible with the Arduino software ecosystem and is supported by online wiki tutorials. This ensures a smooth learning curve for beginners and educators alike.
