100% Arduino compatible UNO R3
The Uno R3 SMD with a Mini-USB data port is an UNO compatible version of the latest R3 iteration of the UNO, which is the most popular of the many development boards available for hobbyists.
It uses an SMD version of the microprocessor rather than the older style DIP package used on the original product and has some additional features.
The Uno R3 SMD operates at 5V which can be supplied via an external power supply or through the USB port connection.
The power source is selected automatically if both are available.
If an external supply is used, it is recommended to use a supply between 7-12V.
The board also has an array of solder points which gives another place to access I2C (SCL/SDA), Serial (TX/RC), 3.3V, 5V and GND which can come in handy.
In both hardware and software, it doesn't differ too much compared with Arduino UNO R3, but uses CH340G Serial USB chip instead of the ATmega16U2.
This is not an Arduino LLC manufactured board.
Like all Arduino compatible boards, it can be programmed using the Arduino IDE via the USB port.
Genuinely pre-tested - programmed for LED to double-blink and to output 'DigitalCure' to the Serial Monitor.
