## Overview

The Arduino Micro Without Headers is a compact, breadboard-friendly microcontroller board powered by the 16 MHz ATmega32U4 chip. Featuring 20 digital I/O pins (7 PWM), 12 analog inputs, and native USB HID support, it enables developers to create custom input devices and embedded projects with ease. Fully compatible with the Arduino IDE, this board offers a seamless programming experience in a sleek form factor perfect for wearable tech, robotics, and portable applications.

## Description

The Arduino Micro board is similar to the Arduino Leonardo, but much smaller - one of Arduino's smallest boards - making it easy to integrate into everyday objects to make them interactive.By including a built-in USB communication, the Arduino Micro can appear as a mouse or keyboard to a connected computer, in addition to a virtual (CDC) serial or COM port.

Review: good - good. I always like these arduino boards.
Review: So powerful in such a small size - I love anything and everything Arduino, I love the micro because it is a small 17 pin long board that fits on all of my breadboards. It is really helpful that it has the regular arduino voltage regulator on it so that I can use all my normal power supply. I was amazed when I locked at the pin layout because so many of the pins have multiple purposes. Some of the I/O pins also work as analog pins and PWM pins. It has a total of 6 Analog in pins (That is the same as the uno!). I love that it uses the same programming environment and I can upload all my codes to it. The one odd thing is that it doesn't come with a cable to write to it, which wasn't a problem for me because it is a pretty standard port, just make sure it is a data cable (not just a charging cable). Overall, I love it. It works perfectly and fits the small form factor that I need sometimes.

## Features

- ATmega32U4 Microcontroller: Powered by the ATmega32U4 chip running at 16 MHz, with 32KB of flash memory, 2.5KB SRAM, and 1KB EEPROM, providing efficient resources for compact and resource-constrained projects.
- USB HID Support: The Arduino Micro supports USB Human Interface Device (HID) functionality, enabling it to act as a keyboard, mouse, or other USB devices—ideal for creating custom input devices and USB peripherals.
- Compact Form Factor: Its small, breadboard-friendly design (1.8" x 0.7") makes it perfect for tight spaces in wearable projects, robotics, and portable devices, without sacrificing functionality.
- 20 Digital I/O Pins & 12 Analog Inputs: Offers 20 digital I/O pins (7 of which support PWM), and 12 analog inputs, allowing for flexible connections to sensors, motors, and other components for embedded applications.
- Full Compatibility with Arduino IDE: Fully supported by the Arduino IDE, allowing for seamless programming and development with Arduino libraries, sketches, and a wide range of community resources for rapid prototyping.

### ⭐⭐⭐⭐⭐ good
*by J***N on April 12, 2025*

good. I always like these arduino boards.

### ⭐⭐⭐⭐⭐ So powerful in such a small size
*by J***E on July 20, 2014*

I love anything and everything Arduino, I love the micro because it is a small 17 pin long board that fits on all of my breadboards. It is really helpful that it has the regular arduino voltage regulator on it so that I can use all my normal power supply. I was amazed when I locked at the pin layout because so many of the pins have multiple purposes. Some of the I/O pins also work as analog pins and PWM pins.

### ⭐⭐⭐⭐⭐ Authentic Arduino at a reasonable price
*by M***Y on January 9, 2015*

This is the real deal, if you are looking for an authentic Arduino in a very small package this is the board you want. As stated in other reviews this board very identical to the Leonardo board except it is much smaller. The device works to emulate keyboard/mouse input which is what I needed it for and the quality of the board and solder joints is as good as you can get. This seller is also selling these at a much more reasonable price compared to others I have seen, beware of others that have a similar price but then charge almost the same amount for shipping which almost doubles the cost of the board. The free shipping this seller offers (without the need for a minimum purchase) makes this the best deal I could find. I only wish I could find one for a reasonable price that doesn't include the headers.
