## Description

desertcart.com: Arduino Uno REV3 [A000066] - ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping : Electronics

Review: Easy buy - There’s a reason this is one of if not the most popular microprocessor, at least for beginners. So easy to use. Compatible with nearly any other component. Compared to most microprocessors, it’s a great price for what you’re getting. Quality is consistent and long lasting.
Review: Exact (and branded) replacement. - Perfect functioning and pin-for-pin match for a generic unit I burned up and needed to replace in a small learning kit. Plug and play install, basically. These are supposed to be more robust as well, so we'll test that, too... I also love the little included tray the board fits perfectly into as well!

## Features

- ATmega328P Microcontroller: Powered by the reliable ATmega328P, running at 16 MHz with 32KB of flash memory, 2KB SRAM, and 1KB EEPROM, offering ample resources for a wide range of basic to advanced electronics projects.
- 14 Digital I/O Pins & 6 Analog Inputs: Features 14 digital I/O pins (6 of which support PWM output) and 6 analog inputs (10-bit resolution), providing flexible options for sensors, motors, and other external components.
- USB Connectivity for Easy Programming: The built-in USB port allows for direct programming and serial communication, enabling a simple connection to your computer for sketch uploading and debugging through the Arduino IDE.
- Compatible with Arduino IDE: Full compatibility with the Arduino IDE ensures easy access to a vast array of libraries, code examples, and community-driven projects, making the Uno a great choice for both beginners and experienced makers.
- Widely Used in Education & Prototyping: The Arduino Uno is a standard in educational environments, widely used for learning and teaching electronics and programming. It's perfect for prototyping, robotics, IoT projects, and more.

## Questions & Answers

**Q: Is this an original Italy made Arduino?? or china product??**
A: If it is Arduino, it will say Arduino on the board.  The china board is called Elegoo, at least the most popular one, and it says Elegoo on it.  Pretty straight forward.  I have this board with the exact same packaging as is in the picture and it says Made in Italy.  It also says Arduino on it.

**Q: Do these come with the arduino.org label and not arduio.cc?  There was a falling out and to support original founders they need to be arduino.cc.**
A: New York, NY, Oct. 01, 2016 (GLOBE NEWSWIRE) -- Arduino, the world’s leading open-source ecosystem for Educators, Makers and IoT developers of all ages, today announced that Arduino LLC (aka Arduino.cc) and Arduino srl (aka Arduino.org) have signed a settlement agreement, and Arduino will become one. Please visit Arduino at this year’s MFNY to talk to the team and see demonstrations of Arduino products and more.By the end of 2016, the newly created “Arduino Holding” will become the single point of contact for the wholesale distribution of all current and future products, and will continue to bring tremendous innovations to the market.

**Q: Are the boards sold by Mp3Car Store genuine? Order is fulfilled by Amazon but some sellers are selling fake boards.**
A: The board I ordered from Amazon and fulfilled buy Dfunlife is a complete FAKE!! My first hint that it might be a counterfeit is the board, made in Italy, was shipped from China. I went to the Arduino web site (which I should have done before I ordered this from Amazon) and did a search on "counterfeit Arduino". It came back with a page of excellent instructions on telling counterfeits. Sure enough, there was my counterfeit. The kicker was the 501k component; it was green on my fake board. The Arduino site has a list of reputable distributers. Arduino uses some of the money from the sell of the REAL Arduino boards to support good causes. Counterfeiters just sell junk that tarnishes the reputation of good companies.

**Q: Does it come with a usb cable?**
A: The USB cable is not included

It was wonderful until I hooked some wires up wrong and burnt something out on the board. All my fault.
