UNO R3 – Atmel ATMega328 16MHz – AVR clone – Arduino compatible

All about the product

The UNO R3 Atmel offered is the most popular module on the market, compatible with the www.arduino.cc project with ATmega328P.

UNO R3 can be used in many microprocessor projects.

Arduino is an open source platform based on hardware solutions and easy-to-use software.

Arduino boards use connected sensors and modules that allow them to read various information from the environment, such as turning on a light, pressing a button, reading the temperature, or more complex information, such as reading messages on a computer. This information can be a signal for the Arduino to turn on a motor, light an LED, or post something to the network. These features give the Arduino amazing capabilities with many applications limited only by our imagination.

UNO R3 features:

• The module is fully compatible with the Arduino Uno R3. This means that it can be programmed via the Arduino IDE using the available libraries.
• The module has:
• - ATmega328 microcontroller - the system operates on a clock signal with a frequency of 16MHz
• - 14 digital inputs/outputs
• - 6 PWM channels – e.g. for servo/motor control
• - 6 analog inputs
• - popular communication interfaces
• - USB connection
• - DC power socket
• - RESET button
• - pins for connecting the AVR programmer

• To run DFRduino, connect the system to your computer using a USB cable and select the Arduino Uno board in the Arduino IDE environment.
• The module is mostly compatible with panels for Duemilanowe and Diecimila
• By default, the BLINK LED 13 program and bootloader are loaded into the module

Notes on construction and connection

• Power supply:
• - The module can be powered via a USB cable and an external device, such as a power supply, battery or accumulator.
• - The power source switches automatically.
• - The power supply is connected to a standard DC outlet.
• - A battery or other source is connected to the POWER connector pins.
• Inputs/outputs:
• - Arduino Pro has 14 digital input/output (I/O) pins.
• - Each pin allows a maximum current of 40 mA, which allows direct connection of LEDs with resistors and control of other integrated circuits.
• - In addition to standard I/O, some contacts have special functions.
• - 6 analog inputs are used to measure voltage (up to 5V!). They can also serve as additional digital pins, in which case we get additional digital pins.
• Programming:
• - ISCP connector allows you to connect an external AVR programmer. A detailed description can be found in the documentation and manual.
• - PL2303 programmer can be used for programming via ISCP connector
• - Programmable via USB using Atmega16u2 intermediate microcontroller
