Lcd Display Module I2C 1602 Blue or Green Backlight Display Module For Arduino Parameter:
Power supply voltage: +5 v
Support the I2C
With the Blue or Green backlight, and contrast to adjust potentiometer
Four line output more simpler
1602 use standard 16 pin ports
1 pin: VVS is grounding power
2 pin: VDD connect 5V positive-supply
3 pin: V0 is LCD contrast adjustment side,it is the the weakest contrast when connect positive-supply, it is the highest contrast contrast when connect grounding power
4 pin: RS is register choice, high levels choose data register , low levels choose Instruction register
5 pin: R/W is Read/write signal wire, high levels choose reading operation,low levels choose choose writing operation.when RS and RW both are low level you can write Instructions or show address.when RS is low level, RW is high level, you can read signal.On the contrary,you can write data.
6 pin: E side is power side.when E from high level to low level, LCD module execute the command.
7-14 pin: D0-D7 are 8 bit double data wire.
15 pin: backlight positive
16 pin: backlight negative
Module dimension: 80mm x 36mm x 12mm
