Product Description

Established in 2011, ELEGOO is a thriving technology company dedicated to open-source hardware research & development, production and marketing.
Our own Quality Management Team will secure the premium quality of our products and we would like to receive your valuable suggestions for our products and make your idea come true.

----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 UNO 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 UNO 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 Speed
Component listing
1pcs ELEGOO UNO R3 Development Board
1 pcs USB cable

It use the same ATmega328 as official Arduino UNO R3 board. The ATmega328 on the UNO R3 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer.
The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library).

There was a problem filtering reviews right now. Please try again later.
Works out of the box too, I look forward to playing around with it.
Still yet to come up with a project to use it in, but have been tinkering.
Need accessories kits for more i/o control

Whenever I buy an arduino for a project now, I get an elegoo. All my creations run on them. I think this is the cheapest they get without having to visit dodgy Chinese websites to install the drivers. I've had one hooked up to a permanent project that's plugged in 24/7. It's been months now, no issues at all. Fantastic value.

A standout feature compared to other "clones" is that Elegoo has stuck to the Rev. 3 design and not tried to improve it with cheaper (SMT) parts. This means you can use the Uno to program an ATMega328 (one is supplied and fitted of course) and then swap it out into your own project without the extra pizazz designed for experimentation.
Microcontrollers are everywhere these days - and while they don't have the OOMPH of even the lowliest Raspberry Pi, they use considerably less electrical energy, run cool and don't require operating systems to make them work. Anyone with a modicum of ability with a soldering iron could rapidly prototype on the Uno and then drop the working controller into their own design.
This is something that definitely isn't possible with a design that has eschewed the DIL package and used the much cheaper surface mount, so hat's off to Elegoo for that.
Great stuff!

Supplied in a shrink wrapped protective box, you get the Elegoo Uno Revision 3 board and the USB cable as shown.
Cable is around 45cm plug to plug.
No special drivers are needed for uploading to this board. The USB interface chip is the same as that used on the genuine Uno - a Mega 16U2 - so the IDE is happy!
The board is very smart in black. It is beautifully made and has the headers labelled on both sides to echo the labels on the board. In this respect it is better than the genuine Uno - as the labels on the genuine Uno for SCL and SDA are hidden by the 6 pin ICSP header. Having these labels on the headers of the ELEGOO board reduces the chances of connecting to the wrong pins when breadboarding.
It comes preprogrammed with the standard blink sketch, so selecting Uno as the board in the IDE, a quick amend to the code in the IDE blink example, selecting the correct port, and compilation and upload was achieved without any problems.
I have built my own basic DIY Uno boards in the past but, at this price, complete with a cable, it's a no brainer to simply get another one of these in future.
It's an absolute bargain - particularly given that the Genuine Uno is around twice the price (and it doesn't come with a cable like the ELEGOO).
I have no hesitation in recommending this if you are looking to have some Arduino fun!
