Arduino UNO R3 CH340G Development Board with cable:

• Microcontroller: The Arduino Uno SMD is based on the Atmel ATmega328P microcontroller.
• Clock Speed: The microcontroller typically runs at 16 MHz.
• Digital I/O Pins: It has a total of 14 digital input/output pins, where a subset can be configured as PWM (Pulse Width Modulation) outputs.
• Analog Input Pins: There are 6 analog input pins.
• UART, I2C, and SPI Communication: The Arduino Uno SMD supports serial communication (UART), I2C, and SPI protocols, making it versatile for interfacing with other devices.
• Flash Memory: The ATmega328P microcontroller has 32 KB of Flash memory for storing the user's program.
• SRAM: It has 2 KB of SRAM for runtime data storage.
• EEPROM: There is 1 KB of EEPROM available for non-volatile data storage.
• Power Supply: The board can be powered through a USB connection or an external power supply. It operates at 5V.
• Input Voltage: The recommended input voltage range is 7-12V.
• Current per I/O Pin: The pins can source or sink a maximum of 20 mA.
• Reset Button: There is a reset button for restarting the microcontroller.
• LEDs: The board typically includes a built-in LED on pin 13, which is often used for simple visual feedback.
• Form Factor: The Arduino Uno SMD has a standard Arduino Uno form factor.
• Programming: It can be programmed using the Arduino IDE through a USB connection.
