8x2 Character LCD - Black Bezel (Parallel Interface)
This little 8-character, 2-line parallel liquid crystal display is a generic equivalent of the Optrex DMC-50448N-AAE-AD LCD. It is incorporated into our Orangutan SV-328 robot controllers, some versions of our A-Star 32U4 Prime microcontroller boards, and our Zumo 32U4 and 3pi robots. It uses the common HD44780 interface, so sample interface code is widely available for a variety of microcontrollers. This is the smallest package we know of for this familiar interface.
You can find sample HD44780 LCD interface code written for a variety of AVR microcontrollers as part of the Pololu AVR library.
|1||Vss||ground (0 V)|
|2||Vdd||5 V logic supply voltage|
