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. This version is optimized in the original version, mainly for customers under the functional requirements for product quality and high case designed both to ensure consistent and compatible with the original, but also easy to use. Microcontroller: ATmega+2560 Compatible with Arduino IDE Operating Voltage: 5V Input: Voltage(recommended) : 7-12V Input Voltage (limits) : 6-20V Digital I/O Pins: 54 (of which 15 provide PWM output) Analog Input Pins: 16 DC Current per I/O Pin: 40 mA DC Current for 3. 3V Pin: 50 mA Flash Memory: 256 KB of which 8 KB used by bootloader SRAM: 8 KB EEPROM: 4 KB Clock Speed: 16 MHz Package includes: 1 x Mega R3 2560 ATmega+2560-16AU Board (Arduino-compatible) 1 x USB cable Review: Arduino mega review Review: Works great for my DCC train project. ## Features - The Mega is 100% compatible with Arduino IDE and most shields designed for the Arduino mega R3，RoHS Compliant - The chip is Atmega+2560-16au and 16u2, same with the official version. - Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes. - Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack) - It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01H4ZLZLQ | | Best Sellers Rank | #21,827 in Computers ( See Top 100 in Computers ) #254 in Single-Board Computers | | Brand | ELEGOO | | Built-In Media | USB cable | | CPU Model | 1.2GHz Cortex A8 Processor | | CPU model | 1.2GHz Cortex A8 Processor | | Compatible Devices | Devices with Arduino IDE and Arduino mega R3 shield support, as well as computers with USB ports | | Connectivity Technology | Bluetooth | | Connectivity technology | Bluetooth | | Customer Reviews | 4.7 out of 5 stars 2,036 Reviews | | Global Trade Identification Number | 00719377200400, 00746591610562 | | Included components | USB cable | | Item Dimensions L x W x H | 5.1L x 10.2W x 2.5H centimeters | | Item Weight | 0.14 Pounds | | Manufacturer | ELEGOO | | Memory Storage Capacity | 256 KB | | Memory storage capacity | 256 KB | | Mfr Part Number | EL-CB-003 | | Model Name | MEGA R3 | | Model Number | EL-CB-003 | | Model name | MEGA R3 | | Operating System | Linux | | Processor Brand | Microchip Technology | | Processor Count | 1 | | RAM Memory Technology | DDR3 | | Total Usb Ports | 4 | | UPC | 719377200400 746591610562 | | Unit Count | 1 Count | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** ELEGOO - **CPU model:** 1.2GHz Cortex A8 Processor - **Connectivity technology:** Bluetooth - **Memory storage capacity:** 256 KB - **Model name:** MEGA R3 ## Images ![ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant - Image 1](https://m.media-amazon.com/images/I/71YFAMutvnL.jpg) ## Questions & Answers **Q: can someone tell me the difference between this ans an official arduino board?** A: The official board comes with a plastic tray that prevents shorts to the bottom of the board. The Elegoo board comes with a USB cable and is available in two colors. There is no functional difference. While the official board may be better quality, I've had no problems with any of the Elegoo boards I've bought. **Q: how much servo motors can this handle? how is the shield compatibility?** A: You have to tie the card to servo drivers to handle motors. The board outputs can handle only a TTL load per pin (about 20 mA per line). I have used a similar card tied to a Sain Smart CNC Micro-Stepping Stepper Motor Driver to handle large stepper motors using up to 4.2 Amps of current: https://www.amazon.com/gp/product/B00DFSF9GE/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 I ran hookup wire from the Arduino board to the interface box(es). Sometimes I used a transistor buffer (per line) so that the 20 mA limit was not overloaded to drive two controllers for the Y-axis with full current capacity on each motor. The transistor I used was a BS270 400mA, 60V N-Channel Enhancement Mode FET. I got the transistor circuit understanding from the book, Exploring Beaglebone. **Q: Is this the exact size as the original mega? i want to make a pcb shield for it on eagle, and will be using sparkfun's mega part footprint** A: I did exactly this, but with a footprint from Element14. My custom shield fits perfectly. **Q: Are the digital outputs 3.3V or 5V?** A: This basically just like the Arduino Mega 2560, the digital pins are 5V as are the analog input pins. There is no version of this that is 3.3V. ATMega 2560 is a 5V chip. No need for level shifters or voltage dividers. There is one 3.3V voltage output pin, which is also typical of the Uno R3 and many other 5V Arduino/clones. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Arduino mega review *by A***R on 7 October 2019* ### ⭐⭐⭐⭐⭐ Works great for my DCC train project. *by T***S on 28 January 2026* ### ⭐⭐⭐⭐⭐ Excelente, barato y funcional! *by C***A on 17 February 2023* La verdad me asustaba un poco que el producto no llegase a funcionar con la plataforma de arduino o que estuviera hecho con mteriales de mala calidad, sin embargo me sorprendieron con la calidad del producto, llego antes del tiempo establecido y funciona de maravilla dentro de la plataforma. ## Frequently Bought Together - ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant - 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 UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino --- ## 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.pl/products/271281741-elegoo-mega-r3-board-atmega-2560-usb-cable-compatible-arduino](https://www.desertcart.pl/products/271281741-elegoo-mega-r3-board-atmega-2560-usb-cable-compatible-arduino) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
