Lcd1602 module with pin header (not need to be soldered by yourself)

The Mega is 100% compatible with Arduino IDE and most shields designed for the Arduino mega R3，RoHS Compliant

The chip is Atmega+2560-16au and 16u2, same with the official version.

Improved and expert version: 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 both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.
