DFRduino UNO R3 - Compatible with Arduino Uno

Compatible with Arduino UNO R3 and Arduino IDE

DFRduino UNO is fully compatible with Arduino UNO R3.
Supports open-source Arduino IDE development platform.
Utilizes Processing/Wiring programming languages.
Abundant tutorials, code examples, and library resources.
Directly write, compile, and upload code in Arduino IDE.

Precautions: To properly install on some computers, the DFRduino Uno R3 requires the driver folder of Arduino 1.0. We have tested and confirmed that the R3 can be programmed on older versions of the IDE. However, when running the R3 for the first time on a computer, you will need Arduino 1.0.

Easy-to-use, High-performance ATmega328 chip

The DFRduino UNO R3 features a DIP-packaged ATmega328 chip, allowing users to easily remove and update firmware for convenient maintenance and upgrades. This makes the DFRduino UNO R3 an ideal choice for various project development and prototype design tasks.

The ATmega328 chip offers a wealth of features, including 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It integrates all the components required for microcontroller operation. Simply connect the DFRduino UNO R3 to a computer via a USB cable or power it with an AC adapter or battery, and users can easily start developing and creating.

User-friendly and Convenient interface design

The DFRduino UNO R3 features a unique color-coded interface design, with red representing power, blue representing analog I/O, and green representing digital I/O, making it easy for users to connect sensors and identify interface types.

Red for Power Section
Blue for Analog I/O
Green for Digital I/O

Convenient USB power supply

No external power supply required, directly power the device through the USB interface for convenience and speed.

Built-in 500mA self-recovering fuse effectively prevents computer USB power overload, ensuring device and computer safety.

Provides an additional 9VDC input interface to meet the power requirements of different scenarios.

Automatic switching between USB and external power supply enables intelligent power management.
