Arduino Leonardo with headers

This development board provides a Compact platform for embedded projects, integrating a single-chip microcontroller to enable USB-native connectivity and straightforward interfacing. It is intended for use in prototypes and learning environments where on-board USB communication and programmable I/O are required.

• ATmega32u4 processor provides native USB connectivity enabling direct host communication
• Development board format allows easy integration with shields and expansion modules
• Header-equipped design simplifies prototyping and access to input/output pins

• Suitable for USB HID and serial emulation projects
• Ideal for educational microcontroller programming tasks
• Used with compatible shields for Rapid prototype expansion

It uses an integrated microcontroller with native USB Interface to handle device and host communications without a separate USB Interface chip.

The fitted headers expose input/output lines for direct connection to sensors, actuators and expansion boards, enabling quicker assembly and testing.

Arduino is an open-source electronics platform consisting of hardware and software. Every aspect is designed to be straightforward so you can learn to code or design a project, quickly and easily. It’s designed for students, programmers, designers, hobbyists and tinkerers.

We have a range of Arduino boards at RS that feature an AVR ATmega microcontroller at the core. Most of the boards feature the 32u4 microcontroller with the Mega boards featuring the ATmega 2560 and the Uno/Nano boards featuring the ATmega328 microcontroller. These Arduino boards are designed to be used with Arduino IDE programming software.
