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, the Arduino Micro offers 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM, providing sufficient resources for advanced applications. - Integrated USB Interface: The onboard USB interface allows the board to communicate directly with a PC or act as a USB device (keyboard, mouse, etc.), utilizing the native USB functionality of the ATmega32U4. - Full Arduino IDE Compatibility: Easily program the Arduino Micro through the Arduino IDE with a simple USB connection, supporting libraries, sketches, and a wide range of shields designed for Arduino platforms. - Compact, Breadboard-Friendly Design: Measuring just 1.8" x 0.7", the Arduino Micro is ideal for tight spaces and breadboard integration, offering 20 digital I/O pins (7 PWM outputs and 12 analog inputs). - Pre-Soldered Headers for Easy Integration: Equipped with pre-soldered male headers, the Arduino Micro simplifies integration with external circuits, sensors, and modules, reducing assembly time and effort for developers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00AFY2S56 | | Best Sellers Rank | 11,069 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 37 in Microcontrollers | | Box Contents | Microprocessor | | Brand Name | Arduino | | CPU Model | Core i3 | | Compatible Devices | Keyboard, Mouse, Personal Computer | | Country of Origin | Italy | | Customer Reviews | 4.7 4.7 out of 5 stars (600) | | Global Trade Identification Number | 07640152111136 | | Item Dimensions L x W x H | 10.2L x 2.5W x 7.6H centimetres | | Item Weight | 9 Grams | | Manufacturer | Arduino | | Manufacturer Part Number | A000059 | | Memory Storage Capacity | 32 KB | | Model Name | A000053 | | Model Number | ARD-A000059 | | Network Connectivity Technology | USB | | Operating System | Linux | | Processor Brand | Microchip Technology | | Processor Count | 1 | | Processor Speed | 16 MHz | | RAM Memory Technology | SRAM | | Smart Home Compatibility | Not Smart Home Compatible | | Total USB Ports | 1 | | UPC | 758399181809 | | Unit Count | 1.0 count | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Arduino - **CPU model:** Core i3 - **CPU speed:** 16 MHz - **Memory storage capacity:** 32 KB - **Model name:** A000053 ## Images ![Arduino Micro with Headers [A000053] - ATmega32U4 Microcontroller, 16MHz, 20 Digital I/O Pins, 7 PWM Outputs, USB HID Support, Compact Design for Embedded Projects, Compatible with Arduino IDE - Image 1](https://m.media-amazon.com/images/I/51S4rKOnjxL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I'd like to dd a GPS module to this, which is the smallest and best option I hve?** A: Look into Adafruit GPS modules compatible with the arduino. I know they have shield GPS modules for the uno so you can probably find an unshielded version to use on the micro. Basically go to adafruit.com and take a look. They also helped design the micro so best chance for compatibility. **Q: What are the dimensions (and weight) of the board? Amazon only seems to list the packaging dimensions.** A: From the Arduino web sitec http://arduino.cc/en/Main/ArduinoBoardMicro "The maximum length and width of the Micro PCB are 4.8cm and 1.77cm respectively, with the USB connector extending beyond the former dimension." Height about 20mm (defined by header pins) Weight 7 g. Also check out the Nano board. **Q: does it have the I2C bus ?** A: Hi, yes! Here is a tutorial with more info: http://tronixstuff.com/2010/10/20/tutorial-arduino-and-the-i2c-bus/ **Q: is this as powerful as the Arduino mega?** A: Simply, no. But powerful for its small size. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works without problems *by M***D on 14 April 2024* Very small profile, works very well ### ⭐⭐⭐⭐⭐ Brilliant bit of kit can be programmed so easily *by J***4 on 8 October 2020* 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. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - Arduino Micro with Headers [A000053] - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - DAOKI 100Pcs 6x6x5 mm Miniature Micro Momentary Tactile Tact Touch Push Button Switch Quality Switch SPST Miniature/Mini/Micro/Small PCB --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/56263945-arduino-micro-with-headers-a000053-atmega32u4-microcontroller-16mhz-20-digital](https://www.desertcart.co.uk/products/56263945-arduino-micro-with-headers-a000053-atmega32u4-microcontroller-16mhz-20-digital) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
