LCD 1602 2×16 character blue & white, LED back light, is a standard type character LCD with 2 lines and 2×16 characters, blue background, and bright white LED back light. This high contrast LCD features the standard Hitachi HD44780 display controller (or compatible), with an optional 2-wire serial interfase (I2C, SDA/SCL) to save on micro controller connections. Several different I2C bus addresses can be selected to run more than 1 display on the same I2C bus the same time. It is supported for example by the Arduino IDE, using the common LiquidCrystal and Wire libraries (examples in the downloads below). The display needs 5V power supply, the LED back light can also be controlled by a software command.
