Serial enabled LCD IIC/I2C/TWI 1602 Serial LCD Module Display Blue Backlight !

This display uses a 2-wire communications method called "IIC", "I2C" "I squared C", and "TWI". All these mean the same thing. This serial protocol that supports multiple devices on the same 2-wire bus (Plus Voltage and Ground, of course)
Power supply voltage +5V
Support I2C protocol.
I2C Address It's either 0x27 or 0x3F
Received an email from a customer saying that his board works with 0x3F
Pin Definition GNDVCCSDASCL
Power supply voltage +5V
Back lit (green with black char color)
Size 82x35x18 mm

As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller. Therefore, LCD1602 with an I2C port is developed to solve the problem. It is also simple to handle. It has only two bidirectional data lines, a serial data line and a serial clock one.
How to wire: GND—GND; VCC—VCC; SDA—A4; SCL—A5

Easy to use. Less I/O ports are occupied, only four - VCC, GND, SDA (serial data line), SCL (serial clock line).
Support IIC protocol. The I2C LCD1602 library is provided, so you can call it directly.
With a potentiometer used to adjust backlight and contrast.
Power supply: +5V
