UNO R3 Development Board Compatible with Arduino

Robotistan UNO with Headers for Arduino with USB Cable This is UNO and it's fully compatible with Arduino. There is a USB cable inside the package for computer connection.   Uno is a microcontroller board based on Atmega328. There are 16 digital I/O pins (6 of them are PWM out), 6 analog input pins, a 16 MHz crystal oscilator, an USB socket, a power socket, an ICSP connector and reset button on the board. There are the all essential parts on the board for microcontroller operations. The board can easily be connected to the computer via usb or can be used with an external adapter of battery. Uno has an Atmega16u2 (It was Atmega8u2 on the Rev 2 model) usb - serial chip for programming and communicaiton with computer via usb. Features: Microcontroller: ATmega328 Operating voltage: 5V Supply voltage (recommended): 7-12V Supply voltage (limits): 6-20V Number of digital I/O pins: 14 Number of PWM pins: 6 Number of analog input pins: 6 Max DC current for each I/O pins: 40mA DC current for
