Arduino Uno R3 Compatible Development Board

Product Description

This UNO R3 compatible development board is a 100% hardware-compatible alternative to the original Arduino UNO. It is based on the ATmega328P microcontroller and includes the ATmega16U2 USB-to-serial controller, allowing fast program uploading and stable USB communication without additional drivers on Linux or macOS.

The UNO R3 board is ideal for beginners, students, hobbyists, and makers. It supports the Arduino IDE and can be used for robotics, IoT, automation, sensors, learning electronics, and prototyping projects. The board includes 14 digital I/O pins (6 PWM), 6 analog inputs, onboard voltage regulation, and a 16 MHz clock.

Programs can be uploaded easily over USB, and the board can also be powered by an external DC supply. Being fully Arduino-compatible, it supports shields, libraries, tutorials, and community projects.

This is a 100% compatible clone board. Functionality is the same as the original Arduino UNO R3.
