The LCD Display 

Screws and nuts

Farbcode/colorcode/code

Value/Position

  

2x M2,5 screw
4x M2,5 nuts
2x plastik washer

Both screws are inserted into the rear holes and secured with the nuts. A plastic washer is 
placed on each nut.
The plastic washer prevents the metal nut from being damaged. 
short-circuits on the board.

The distance between the LCD and the board is 2.5 mm and is given by the plastic 
connector of the connector on the LCD. 
The nut is 2 mm thick, the washer 0.5 mm - so the display should now rest horizontally on 
the PCB.
