## Overview

The ELEGOO UNO R3 Development Board features a powerful ATmega328P microcontroller running at 16MHz, 32KB flash memory, and an ATmega16U2 USB-to-serial interface chip for faster data transfer. Compatible with Arduino IDE and all existing shields, it supports flexible power inputs (5V USB and 7-12V DC) with a recommended 9V 1A for stability. Its smart design includes a resettable fuse for protection and clearly labeled I/O pins for easy wiring, making it the ideal choice for professional-grade prototyping and development.

## 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.

## 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

## 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.
