The board is a microcontroller board based on the CH340. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
This is compatible board with an Atmega328p and a CH340G serial converter, 100% Compatible with Arduino UNO R3.
This board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes. Stronger RESET circuit.
Friendly: the board is easy to use for Arduino starter, 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.
We strive to put our hundred percent to meet your requirements and try our best to achieve your satisfaction!
