Arduino UNO R3:

To be honest its better than official arduino UNO R3 board, the reason is that it have 2 keys, extra Male headers in parallel with female headers and original Atmel ATMega328 micro controller which is removable like the official arduino UNO R3.

Arduino Uno R3 is a microcontroller-based development board. Arduino UNO and other boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online by utilizing this R3 kit. You can tell your Arduino UNO r3 what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

arduino uno board microcontroller atmega based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. arduino uno board microcontroller atmega You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
