I got 4 of them and never had any issues, great speed, board looks to be very good quality. I've ran cncs with them and there super reliable. 5 stars baby Review: Works as expected Mac OS 10.13.6 i7 Mac Mini - Five Stars This Arduino clone board worked perfectly for me right out of the box. No drama, no issues, no system software updates. Just upload the newest compatible version of Arduino with your OS. I am a reasonably experienced multi-platform computer user, but Mac is my preferred platform. For me, running Mac 10.13.6 High Sierra on a 2012 Mac Mini, Arduino 1.8.19 works flawlessly. AccelStepper, ezButton, and all the other popular libraries worked first time. The supplied USB cable was too short for my purposes, so I had to substitute a known working data plus power USB cable. Also, the device does not like being ported through hubs, though with the right hub it probably works fine. I just didn't bother. I did get one "device drawing too much USB current" alert from my Mac OS, but I have no idea why. It was just sitting there. I think it was a fluke or a momentary short or something as I had the board laid out on my desktop. Other than that, works like a charm. Accepts the XikenTec HCDC Shield. Not all clones are created equal. See my review of "another brand" of Uno clone, the very cheapest one currently on desertcart. I'm ordering another one of these Elegoo right now to replace that one, which I am sending back. The Elegoo branded Uno clone seems like a good compromise between clone pricing and OEM compatibility. Or, screw around loading drivers and fiddling with your OS for a day or two and save an additional five dollars. :-) ## Features - Clear prints on the female header connector, more precise and easier to use the wire. - The ELEGOO UNO R3 BOARD now uses an 16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory. - Control using ATMEL ATMEGA+328P chip(the same with Arduino UNO R3) - 100% compatible with the Arduino IDE and RoHS Compliant - We have always cared about the customer experience and improve the product function details. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 5,030 Reviews | ## Product Details - **Brand:** ELEGOO - **Connectivity Technology:** USB - **Memory Storage Capacity:** 32 KB - **Model Name:** ELEGOO UNO R3 Board - **Ram Memory Installed Size:** 32 KB ## Images ![UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino | Compatible with Arduino IDE Projects, RoHS Compliant - Image 1](https://m.media-amazon.com/images/I/71cvvGHcMwL.jpg) ## Questions & Answers **Q: Is this the same thing as an arduino?** A: Arduino is just a specification for a microcontroller. Although there is an official "Arduino Brand" this model does 100% of what that model does for $5 less. I have a kit that connects every GPIO pin of Arduino, and it connected fine. So for all intents and purposes, this is "the same thing as an arduino." **Q: Ordered two of these and get the same error message: avrdude: ser_open() : can't open device "\\.\COM4": the system cannot find the file specified.** A: When this happens, I've fixed it by closing the Arduino IDE, unplugging my USB cable from the UNO, plugging it back in, and restarting the IDE. (Save the file before closing the IDE, if desired.) This has always corrected the issue for me, even when the IDE shows an Arduino on COM4 and it's selected yet still seems unavailable. **Q: Does this use the CH340 ?** A: No. And no. He wants to know the USB chip, not the MCU chip. The USB chip is a CP2021 or whatever, it isn't the CH340. **Q: is the Elegoo compatible with the official Arduino program? (1.8.1 to be exact)** A: While I have not updated to 1.8.1 yet, I have used it with previous versions with no issues, so I see no reason why it should not work with the latest. I have used 3rd party programs and libraries as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing board! *by C***S on March 26, 2026* Forget the name brand boards, you cannot beat these things for the price.

These are easy to use. There are a ton of tutorials out there that will get you started right away. I use these to prototype as well as make complete projects. They have always performed well. I do not often do projects that use most or all of the pins, usually I use about half of them and have never had an issue with the board. ## Frequently Bought Together - ELEGOO UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino - 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 - ELEGOO 3pcs Breadboard 830 Point Solderless Prototype PCB Board Kit for Arduino Proto Shield Distribution Connecting Blocks --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/27763963-uno-r3-board-atmega328p-with-usb-cable-arduino-compatible-arduino](https://www.desertcart.sc/products/27763963-uno-r3-board-atmega328p-with-usb-cable-arduino-compatible-arduino) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-06-19*
