## Description

Original Arduino A000093 Arduino A000093 Board Micro without Header Core ATMega32 Durable and Robust

Review: Works without problems - Very small profile, works very well
Review: Brilliant bit of kit can be programmed so easily - This is probably the easiest device of its type I've ever used, such a great library of code samples make it a doddle to cut and paste code to get this to do complex stuff quickly.

## 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.

### ⭐⭐⭐⭐⭐ A lot of functionality for a very good price. Much better value than the old BASIC ...
*by R***M on 2 December 2014*

Is it the genuine article? Yes it is, as far as I can tell. Much easier to use with a breadboard than my Leonardo. it just plugs in. A lot of functionality for a very good price. Much better value than the old BASIC Stamps I used before.
