Connected to computer. (If this module cannot be recognized by your computer, please install the driver first) 2. Opened IDE and loaded Blink sketch. 3. Set board to Leonardo and selected the appropriate COM port (It showed up in the list already identified as a Leonardo). 4. Connected an LED to pin 9 and modified the sketch accordingly. 5. Hit upload and within a few seconds having a blinking LED. Package Includes: 3 x Pro Micro ATmega32U4 5V 16MHz Module Review: Beware of non-standard length - The boards looks and work just fine. But there's something to be aware of: the length is non-standard. Those are noticeably longer that usual, if you have confined area to use it - this board might not fit in there. Review: Simple Setup and Solid Performance for Makers of All Levels - The Pro Micro development board exceeded my expectations. Setting it up was relatively straight forward. Within minutes, I had the board connected and running for my project. The compact size is a huge plus, fitting perfectly into my small-scale projects without any hassle. The USB functionality worked well, and the board’s responsiveness was impressive. I think this is a good choice for anyone looking to dive into development projects with minimal setup time. ## Features - The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with external USB interface. - 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Development boards such as Nano board. - It can accept voltage up to 9V DC as there is a voltage regulator on board.The maximum voltage allowed on the RAW pin is 9V, 6-7V input recommended. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC. - 4 x 10-bit ADC pins, 12 x digital I/Os,Rx and Tx hardware serial connections - Each one is in their own anti-ESD bag with 2 rows of header pins. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09C5H78BP | | Best Sellers Rank | #1,390 in Single Board Computers (Computers & Accessories) | | Brand | Hosyond | | Built-In Media | 3 x ATmega32U4 Pro Micro | | CPU Speed | 16 MHz | | Compatible Devices | Arduino IDE, Leonardo, Genuino Micro | | Connectivity Technology | USB | | Customer Reviews | 4.1 out of 5 stars 74 Reviews | | Included Components | 3 x ATmega32U4 Pro Micro | | Manufacturer | Hosyond | | Mfr Part Number | C038-3PCS | | Model Name | Pro Micro ATmega32U4 | | Number of Items | 3 | | Operating System | Linux, Windows, macOS | | Processor Brand | Atmel | | Processor Count | 1 | | Processor Speed | 16 MHz | | RAM Memory Technology | LPDDR3 | | Total Usb Ports | 1 | | UPC | 761344888463 | | Warranty Description | NO | | Wireless Compability | 802.11b | ## Images ![Hosyond 3pcs Pro Micro ATmega32U4 for Leonardo 5V 16MHz Development Board Micro-Controller Compatible with Arduino IDE - Image 1](https://m.media-amazon.com/images/I/71t0rN9RMmL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Beware of non-standard length *by Y***Y on May 22, 2026* The boards looks and work just fine. But there's something to be aware of: the length is non-standard. Those are noticeably longer that usual, if you have confined area to use it - this board might not fit in there. ### ⭐⭐⭐⭐⭐ Simple Setup and Solid Performance for Makers of All Levels *by P***G on June 14, 2024* The Pro Micro development board exceeded my expectations. Setting it up was relatively straight forward. Within minutes, I had the board connected and running for my project. The compact size is a huge plus, fitting perfectly into my small-scale projects without any hassle. The USB functionality worked well, and the board’s responsiveness was impressive. I think this is a good choice for anyone looking to dive into development projects with minimal setup time. ### ⭐⭐⭐⭐ Solder pads lifted VERY easily *by M***. on December 24, 2025* Works great, but the solder pads lifted off the PCB VERY easily. If you can strain relief your connectors, you'll be fine. The USB port connector came off I think the 4th time I plugged it in because they didn't use solder pads to hold it to the PCB and there was no mechanical connection. Otherwise, the micro works well. --- ## 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.ie/products/355395705-hosyond-3pcs-pro-micro-atmega32u4-for-leonardo-5v-16mhz-development](https://www.desertcart.ie/products/355395705-hosyond-3pcs-pro-micro-atmega32u4-for-leonardo-5v-16mhz-development) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-09-23*
