The UNO R3 SMD Clone is a customized modification of Arduino UNO R3. The 16 MHz ATmega328 microcontroller on this board has been mounted through the Surface Mounted Diode (SMD) technology.

UNO R3 SMD Clone is programmable through the Arduino IDE. You can use the USB port for configuration.

UNO R3 SMD also has solder points in an array. You can use them as an extra option to access GND, I2C (SCL / SDA), 3.3V / 5V, and Serial (TX / RC).

There is a CH340 Serial to USB converter on this UNO R3 Clone. The standard female I/O headers have additional holes next to them.

You can use these holes for custom soldering including wires or additional male or female headers. In addition, you can solder the additional headers to either side of the board depending on your requirement.

The box includes a 40-Pin Male pin header.
