This Arduino UNO R3 compatible development board is a practical and affordable solution for electronics, automation, robotics, and learning projects. It integrates the ATmega328P microcontroller and allows direct programming via a USB Type-C port, using the CH340G chip that manages communication between the computer and the microcontroller. It is suitable for both beginners and advanced users who want a stable and easy-to-use platform.

The board operates at a 5V logic voltage and offers a generous number of digital and analog pins, making it suitable for connecting sensors, modules, relays, displays, and other peripherals. It features 14 digital input/output pins, of which 6 can be used for PWM, as well as 6 analog pins A0-A5. Additionally, 3.3V and 5V output pins are available to power compatible modules.

Programming is done via USB, and for proper recognition by the computer, installing the CH340 driver may be necessary. Generally, this driver is installed along with the Arduino IDE, but in some cases, the board may be incompatible with certain newer versions of the driver, so it is recommended to use the version indicated in the product's download section. Power can be supplied directly through USB at 5V or via the Vin pin or dedicated jack, within the 7-12V range, with 9V recommended for stable operation.

To upload code, the CH340 driver is required (download Driver). Usually, the driver installs together with the Arduino IDE software used for programming the board (download Arduino IDE). The board may be incompatible with the latest version of the CH340 driver (2023). Please download the driver from the Download section.

Usage:

The board is used for rapid development and testing of electronic projects based on the ATmega328P controller. It is suitable for controlling sensors, LEDs, communication modules, displays, motors, relays, and other common components within the Arduino ecosystem.

For use, connect the board to the computer via the USB Type-C cable, then select the corresponding model in the Arduino IDE and the serial port detected by the system. If the board is not recognized correctly, the appropriate CH340 driver must be installed. After installation, code can be uploaded directly via USB without an external programmer.

The board can be powered directly through the USB port at 5V or from an external power source of 7-12V connected to Vin or the power jack. For stable operation, a voltage of 9V is recommended when using external power. When connecting modules and sensors, the board's 5V logic voltage must be respected, and higher power consumers should be powered separately if they exceed the available power capacity on the board.
