Key Features of Original Arduino Micro No Headers
- Ultra-Compact Form Factor: At just 48 x 18 mm, the Micro is Arduino's smallest board - ideal for space-constrained builds, wearables, and embedded installations where every millimeter matters.
- No Headers for Maximum Flexibility: The headerless design lets you solder pin headers, right-angle connectors, or direct wires depending on your exact mounting and connection requirements.
- Native USB with ATmega32U4: Unlike boards that rely on a secondary USB-to-serial chip, the Micro's ATmega32U4 handles USB communication directly - enabling it to appear as a mouse, keyboard, joystick, or MIDI device to any connected computer.
- Breadboard Compatible: Solder standard male headers and the Micro drops directly into a solderless breadboard with accessible pins on both sides for rapid prototyping.
- 20 Digital I/O Pins with 12 Analog Inputs: More analog inputs than the Uno, giving you expanded sensor connectivity for data acquisition and monitoring projects.
- 7 PWM Outputs: Control motors, dim LEDs, and generate analog-like signals across seven dedicated PWM channels.
- Full Arduino IDE Compatibility: Program using the familiar Arduino IDE with access to thousands of libraries, examples, and community resources right out of the box.
- SPI, I2C, and UART Interfaces: Connect to sensors, displays, communication modules, and other peripherals using all standard serial protocols.
- Micro-USB Connection: A single Micro-USB cable handles programming, serial communication, and power delivery - no external programmer needed.
- HID and MIDI Capable: Build custom input devices, MIDI controllers, game controllers, and automation tools that interface natively with computers without additional drivers.
- Smallest Official Arduino Board: When your project demands a full-featured Arduino in the tiniest possible package, the Micro delivers all the capability of larger boards in a fraction of the footprint.
- Customizable Connections: The no-headers version is purpose-built for makers who want to choose their own connector style - whether that's standard headers, spring terminals, direct soldering, or custom PCB integration.
- Native USB Opens New Project Categories: The built-in USB HID capability means you can create projects that simply aren't possible with Uno or Nano - custom keyboards, mouse emulators, game pads, and MIDI instruments.
- Professional-Grade for Production: The headerless format is preferred for permanent installations and production builds where soldered connections provide superior reliability over pin headers.
