I’ve used it to run many of my small scale engineering projects like a bionic arm, submarine, and a robotic car. It works like a charm, has great connectivity with multiple ports, very compatible with different power supplies, plenty of documentation online + has withstood some abuse. Great for beginners and even more experienced engineers alike. One of the best electronic purchases I’ve made as it’s nearly $35 cheaper than an actual Arduino. Review: Amazing board! - Forget the name brand boards, you cannot beat these things for the price. 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 ## 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 | |---------------|-------| | ASIN | B01EWOE0UU | | Best Sellers Rank | #14 in Single Board Computers (Computers & Accessories) | | Date First Available | April 28, 2016 | | Item Weight | 0.96 ounces | | Item model number | EL-CB-001 | | Manufacturer | ELEGOO | | Product Dimensions | 3.15 x 2.36 x 0.39 inches | ## 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 ![ELEGOO UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino - Image 1](https://m.media-amazon.com/images/I/71cvvGHcMwL.jpg) ## Available Options This product comes in different **Size** options. ## 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 ### ⭐⭐⭐⭐⭐ I love this thing *by K***A on July 6, 2026* This “off brand Arduino” is definitely on par with the real thing.
