Meet the Arduino Microcontrollerboard, a compact Arduino-style microcontroller powered by the ATmega32u4 with native USB. This unpopulated variant ships without header connectors, ideal for custom wiring, space-constrained projects, and precise PCB integrations.

Key Features & Design

• Microcontroller: ATmega32u4 with built-in USB for easy programming and USB HID capabilities.
• Unpopulated form: Micro version shipped without header pins, ready for custom soldering and bespoke interconnects.
• Compact form factor: Small footprint designed for tight spaces and custom PCBs.
• Arduino compatibility: Works with the Arduino IDE and broad ecosystem of libraries and examples.
• USB connectivity: Integrated USB interface for power and programming via a micro USB connection.

Performance / Benefits

Leverage native USB support to build versatile projects, including HID devices like keyboards or mice, with straightforward programming through the Arduino IDE. The bare-board design minimizes extraneous hardware, giving you a clean slate for tailored connections and compact, professional-grade integrations—from wearables to compact automation prototypes.
