This is the low cost version of the popular Arduino Uno R3.
This board is assembled with the CH340 USB to Serial converter chip, in stead of using a Atmega16U2 chip. PLEASE NOTE, you might have to install the CH340 driver on your computer to be able to program and communicate with this board. The CH340 USB drivers are not installed by default on most computers. Please rather buy the more expensive "non CH340" version of this board if this is going to be a problem! The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation(when not using USB), this board is identical to the more expensive version without CH340 chip.
The ATmega328P microcontroller is identical to the one used on the genuine boards.
This is an Arduino Compatible board. It is NOT an original Arduino board manufactured in Italy. It is manufactured in China like all the other low cost Arduino compatible boards. The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, 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. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it uses the CH340 chip.
Please note these are VERY LOW cost boards from China. If you expect a premium product, this is NOT for you. These boards might have scratches on them, might not be the cleanest, and the packaging might have scratches or small tears. For example, if the board has pin headers, they are often ship to us from China all together in a bag, and the pins might be slightly bent or protrude through the bag. If this is not acceptable, please look for a more premium product. After all our costs (10% GST, over 10% eBay/PayPal fee and "Free" shipping we have to pay for), you can appreciate that there is very, very little profit margin left for us. We bring you these products at a very good price, but keep in mind it is a very low cost, cheap and nasty cheap product - exactly the same as similar price products sold by other sellers.
