## Overview

The UNO R3 Rev3 Development Board by ElectronKid is a high-quality, fully Arduino-compatible microcontroller platform featuring an ATMEGA328P CPU and an upgraded ATmega16U2 USB interface chip. Operating at 16MHz with 14 digital I/O pins (6 PWM), 32KB flash memory, and enhanced USB HID capabilities, it offers stable performance and versatile connectivity for professional-grade electronics prototyping.

## Description

The latest Arduino UNO R3, released by Auduino in 2012, is an easy-to-use open source electronics prototyping platform. In both hardware and software, it doesn’t differs too much compared with Arduino UNO, but uses ATMega16U2 instead.   Difference between UNO R3 2012 and UNO 2011:   1. Pin of changes: next to the AREF pin both I2C-pin (SDA and SCL, just Analog 4 and 5 of the copy, not the additional I2C interface), plus the two next to the RESET pin, one IOREFallow expansion board voltage onboard, this pin expansion board just told the onboard voltage (such as UNO 5V, can be seen as the power pins copy, does not provide the level pull), the other is laterScratch placeholder pin.   2. More stable RESET circuit. The RESET key position has changed, which has been moved to the corner near the USB interface board, more convenient and press.   3. The ATmega16U2 instead 8U2, and that does not mean that the 16K flash of UNO R3 make your code run faster, this update is a service of the USB interface chip, theoretically It UNO can simulate USB the HID, such as MIDI / Joystick / Keyboard.
