Description

UNO R3 is an easy-to-use open source controller launched in 2012. There is no major change in hardware compared to UNO. The biggest difference lies in the USB to serial port circuit part, which uses an ATMega16U2 microcontroller instead, so the cost is also higher. The software part is the same as before, with no major changes.

Function:

1. Pin changes: Two I2C pins are added next to the AREF pin (SDA and SCL are just copies of Analog 4 and 5, not additional I2C interfaces). In addition, two pins are added next to RESET. One is IOREF, which allows the expansion board to adapt to the onboard voltage. This pin only tells the expansion board what the current onboard voltage is (for example, UNO is 5V, which can be seen as a copy of the power pin and does not provide level pull-up). The other is a placeholder pin to be used later.

2. More stable RESET circuit. The position of the RESET button has also changed, and it has been moved to the corner of the board near the USB port, which is more convenient to press.

3. ATmega16U2 replaces 8U2. This does not mean that the R3 with 16K flash can make your code run faster. This update is for the USB interface chip. In theory, it allows UNO to simulate USB HID, such as MIDI/Joystick/Keyboard.

Features:

The original circuit diagram is open, and the development software interface is free to download. You can also modify it according to your needs. The download program is simple and convenient. You can simply use sensors and various electronic components to connect (such as: LED lights, buzzers, buttons, photoresistors, etc.) to make a variety of interesting works. Using a high-speed microprocessor controller (ATMEGA328), the development operation interface and environment are very simple and easy to understand, which is very suitable for beginners to learn.
