Compatible with Arduino IDE, it supports USB 5V and 7-12V DC power inputs, includes a PTC resettable fuse for short-circuit protection, and has clearly labeled I/O pins for easy wiring. RoHS compliant and lightweight, it’s the perfect development board for professional-grade prototyping and hobbyist projects alike. ## Description ----The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer.----The ELEGOO R3 puts SDA and SCL pins beside the AREF. Besides, there are two new pins placed near the RESET pin. One is the IOREF that allows the shields to adapt to the voltage provided from the board and the other one is reserved for future purposes. The ELEGOO R3 works with all existing shields and can adapt to new shields which use these additional pins.Features* ATmega328P microcontroller* Input voltage - 7-12V* 5V Electric current: 500MA* 3.3V Electric current: 50MA* 14 Digital I/O Pins (6 PWM outputs)* 8 Analog Inputs* 32k Flash Memory* 16Mhz Clock SpeedComponent listing:1pcs ELEGOO R3 Development Board1 pcs USB cableWe have the manufacture factory, making productions and selling by ourselves.So we can control the quality of our productions by ourselves for you.We’d like to receive your valuable suggestions for our products and make your idea come true. Review: work as described - Product is very good and work as described Price is competitive Review: Jättebra köp - Fungerade precis som jag hade förväntat mig, bra produkt ## Features - High-quality UNO R3 controller board functional compatible with Arduino IDE - ELEGOO UNO R3 board uses an ATMega16U2 as a Serial interface Chip and an ATmega328P as a Microcontroller Chip making it more faster in transfer rates and better at storage and operation with more memory store - Supports USB 5V Input and 7V -12V DC Input and if you are working on small projects we suuggest you use 9V1A Input to get a more stable user experience - A PTC resettable fuse could protect your board from shortcut caused by incorrect wiring - I/O interface name and function are indicated on the flank of the Female Header Connector making it much easier for wiring ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01EWOE0UU | | Are Batteries Included | No | | Best Sellers Rank | #85,375 in Computers ( See Top 100 in Computers ) #1,307 in Single-Board Computers | | Brand | ELEGOO | | Color | Black | | Computer Memory Type | 72-Pin EDO SIMM Memory | | Customer Reviews | 4.7 4.7 out of 5 stars (4,817) | | Date First Available | 7 October 2016 | | Graphics Card Description | Integrated | | Graphics RAM Type | DDR DRAM | | Hard Disk Description | HDD | | Hard Drive Interface | ATA-4 | | Item Weight | 27.2 g | | Item model number | EL-CB-001 | | Manufacturer | Elegoo | | Memory Technology | SRAM | | Operating System | Windows 10 | | Optical Drive Type | BD-R | | Processor Brand | Atmel | | Processor Count | 1 | | Processor Speed | 0.02 GHz | | Processor Type | Cortex A8 | | Product Dimensions | 8 x 5.99 x 0.99 cm; 27.22 g | | RAM Size | 2 KB | | Series | ELEGOO UNO R3 Board | | Standing screen display size | 3 | | Wireless Type | Bluetooth | ## Product Details - **Brand:** ELEGOO - **CPU model:** Cortex A8 - **Installed RAM memory size:** 32 KB - **Memory storage capacity:** 32 KB - **Model name:** ELEGOO UNO R3 Board ## Images ![ELEGOO UNO R3 Microcontroller Board ATmega+328P ATMEGA+16U2 with USB Cable | ... - Image 1](https://m.media-amazon.com/images/I/71dFhqWoFiL.jpg) ## Questions & Answers **Q: The computer cannot recognise the UNO R3 board?** A: Please check if your computer makes a new device recognition sound when the board is plugged in. If not, use another USB cable to connect to another USB port. Please connect the UNO board to another computer to make sure it is not a computer problem. **Q: The UNO board heats up when it is powered on?** A: Please disconnect all connections to the control board and try to use another USB cable to check the problem. If there is still a problem, please send us a picture of the heating area for troubleshooting. **Q: Unable to upload code to UNO board?** A: (1) Please make sure you have selected the correct board type and port #COM. (2) When you press the reset button, does the LED flash two or three times? If not, it may be that the bootloader is broken. Or just reach out to us. **Q: Do I need extra parts to start?** A: No. The board and USB cable are included. You can start programming right away. **Q: Is this suitable for 12+ students?** A: Yes. Recommended for learners under 12 with adult guidance as needed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ work as described *by M***I on 4 May 2026* Product is very good and work as described Price is competitive ### ⭐⭐⭐⭐⭐ Jättebra köp *by K***. on 12 January 2022* Fungerade precis som jag hade förväntat mig, bra produkt ### ⭐⭐⭐⭐⭐ I love this thing *by K***A on 6 July 2026* This “off brand Arduino” is definitely on par with the real thing. 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. ## 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? - 🛒 **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.nz/products/254187770-elegoo-uno-r3-microcontroller-board-atmega-328p-atmega-16u2-usb](https://www.desertcart.nz/products/254187770-elegoo-uno-r3-microcontroller-board-atmega-328p-atmega-16u2-usb) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-27*
