This product is a combo of an Arduino UNO R3 SMD development board and a USB Type A to Type B programming cable. The Arduino UNO R3 SMD is based on the ATmega328P microcontroller and is designed for embedded system development, learning, and prototyping. It operates at a clock speed of 16 MHz and works on a 5 V operating voltage, making it suitable for a wide range of electronics applications. The board provides 14 digital input and output pins, including six PWM-capable pins, along with six analog input pins. These features allow easy interfacing with sensors, actuators, displays, and other electronic modules. Standard communication protocols such as UART, I2C, and SPI are supported, enabling integration with commonly used peripherals. The included USB Type A to Type B cable is used to connect the Arduino board to a computer for programming, serial communication, and power supply. It supports the USB 2.0 standard and provides stable data transfer along with reliable 5 V power from a computer or laptop USB port. The compact 30 cm cable length is suitable for desks, labs, and educational setups. This combo is commonly used by students, hobbyists, educators, and developers for robotics projects, automation experiments, IoT learning, and general microcontroller-based applications. The board is compatible with the Arduino IDE and works with Windows, macOS, and Linux operating systems.
