Flash memory: 32 KB
RAM memory: 2 KB
EEPROM: 1 KB
Digital inputs/outputs: 14 GPIO, 6 of which can be used as PWM
Analogue inputs: 6
Compatibility with SPI and I2C buses
USB connector with CH340 chipset for serial communication
ICSP connector for programming
Reset button

Advantages and typical uses

This board is compatible with the Arduino IDE development environment, allowing you to program and control robotics, automation, home automation, electronic prototyping and embedded systems projects. Thanks to the CH340 chipset, it offers a stable USB connection compatible with multiple versions of Windows, although it is necessary to install the corresponding drivers before use.

The Arduino Uno R3 board is ideal for those looking for an economical alternative without sacrificing functionality, making it perfect for students, makers and professionals who need a versatile and easy-to-use microcontroller.

Compatibility and installation

To use this board, it is necessary to install the CH340 drivers, available on the official website or in trusted repositories. Once installed, the board is automatically recognised by the system and can be programmed from Arduino IDE without problems.

The board is compatible with all versions of Windows, including Windows 11, and can be powered via USB connection or external sources such as AC/DC adapters or batteries.

Customer Questions & Answers

What are the exact dimensions and approximate weight of the UNO R3 board with ATmega328P-PU + CH340?

The board generally measures 68.6 mm × 53.4 mm × 15 mm and weighs approximately 25 g. Tolerances may vary slightly depending on the specific manufacturer, but are usually within ±0.5 mm.

Does it require any additional configuration or installation to run on operating systems other than Windows, such as Linux or macOS?

For Linux and macOS, many modern distributions recognise the CH340 automatically, but in some cases you may need to download and install specific drivers. It is recommended to check the operating system version and consult the manufacturer's official documentation if detection issues arise.

Is it possible to power the board solely via USB, and what is the safe voltage range for the VIN input or DC jack?

Yes, it is possible to power the board only via USB (5 V). For the VIN input or DC jack, the safe operating range is 7 to 12 V, although it can tolerate between 6 and 20 V with increasing risk of overheating at extreme values.

What is the expected service life and what maintenance considerations should be taken into account to ensure durability?

Service life depends on the number and type of connections/disconnections, electrical surges and exposure to dust/humidity. Cleaning the pins regularly and avoiding electrical overloads can extend service life, typically beyond 5 years under normal use.

Is this board compatible with Windows 11?

Yes, the Arduino Uno R3 board with CH340 chipset is compatible with Windows 11, but you need to install the CH340 drivers before using it.

What is the difference between the CH340 chipset and the original 16u2?

The CH340 chipset is an alternative USB-to-serial converter to the classic 16u2. It is more economical and compatible with multiple systems, but requires installation of specific drivers.

What is included in the package for the CH340 compatible Arduino Uno R3 board?

It includes the Arduino Uno R3 board with Atmega328p-PU microcontroller and CH340 chipset, plus a USB cable for connection and programming.

Can I program this board with Arduino IDE?

Yes, it is fully compatible with Arduino IDE, just make sure to install the CH340 drivers so the system recognises the board.
