Uno" means one in italian and was chosen to mark the release of Arduino Software IDE 1.




The second one is a not connected pin, the IOREF that allow the shields to adapt to the voltage provided from the board.
0 pinout: added sda and scl pins that are near to the aref pin and two other new pins placed near to the RESET pin, which operates with 5V and with the Due that operates with 3. 3v. We strive to put our hundred percent to meet your requirements and try our best to achieve your satisfaction! In future, shields will be compatible with both the board that uses the AVR, that is reserved for future purposes. The board is a microcontroller board based on the ch340 .


Also, it comes with the USB cable. This microcontroller can be used by connecting it to a computer with a USB cable or power it with an AC to DC adapter. Beautiful look & packaging: cool yellow-black design which is a departure from the standard, dull, black boards, the yellow silk screen on black mask make it easy to read the pin labels.

Cuttable: you can cut them, like soldering iron, or score them with some electronic tool, and snap them off; They can be cut to any size if needed.

What you getyou will get: espduino development board: 1pcs; USB cable: 1pcs. Then you can compile and download the Arduino source code.
Txt; 2 select the board type as “nodemcu v1” or other choices. About this boardthe espduino has a esp-13 wifi module. So, all of the esp8266 source code and bin files can also be used on this board. The chip is also esp8266. Importantly, the Arduino code is also suitable with this board. Serial chipthe serial chip is ch340C. So, you should install the CH340 driver program before use it.
