Arduino UNO R3 Clone board
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, with these features on board can make the experiments fast and easy. the USB to Serial programmer chip is CH340T which plug and play in most operating systems. on board switch KEY_L one pin is connected with GND and and the other with Male header KEY_L,  KEY_H one pin is connected with VCC 5V and and the other with Male header KEY_H,
Arduino Uno R3 is a microcontroller board based on the ATmega328P. 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.. 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.
"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
