5V LCD 1602 blue backlit LCD screen 1602A-5V  

Blue background, white text  
Standard 16X2 LCD display character modules

1602 a standard 16-pin interfaces, including:

 

1th feet: VSS power

 

2nd leg: VDD 5V power supply

 

3rd leg: V0 for liquid crystal display contrast adjustment side, contrast when the weakest are power supply, grounding power the greatest contrast, contrast is too high will have a "ghosting", can be used by a 10K potentiometer to adjust the contrast

 

4th leg: RS to register options, select a data register, high level low level select the instruction register.

 

The 5th foot: r/w for read/write signal lines, high voltage for read operations, to write low level. When RS and RW work for low level address can be written instructions or, as RS for low-level RW for high level can be read off busy signals, when RS RW high level to low level data can be written.

 

6th leg: e end-for-end, when e duanyou-level jumps to a low level, LCD module executes the command.

 

Di7~14 feet: D0~D7 for 8-bit bidirectional data line.

 

The 15th foot: backlight power supply cathode

 

The 16th foot: backlight power supply negative pole
