This is a basic 16 character by 2 line display.
White text on Blue background.
This is based on the most common Hitachi's HD44780 parallel interface chipset.
The Hitachi HD44780 is a handy LCD display which can be easily interfaced to a microcontroller in either 8 bit mode or 4 bit mode depending on the number of microcontroller pins you have to spare.
The LCD only displays a text output however this is a user interface for display information about battery power or distance to an object.
The nominal operating voltage for LED backlights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color. Non-LED backlights often require higher voltages.
The LCD is usually interfaced via 16 pins which are labeled as shown below:
3 - 5V
Register Select - Command (0) or Character (1)
Read/Write - Write (0) or Read (1)
Enable - Enable data transmit (0)
Data Bit 0
Data Bit 1
Data Bit 2
Data Bit 3
Data Bit 4 - used in 4 bit operation
Data Bit 5 - used in 4 bit operation
Data Bit 6 - used in 4 bit operation
Data Bit 7 - used in 4 bit operation
