    This is cheapest GLCD that i found.


    Product is missing datasheet. There is no clear mart witch display chip or interface is used. Mine just have mark 12864B which is not very helpful.


    After lot of time wasted this is ST7920. Wiring for 5V supply is here You can use u8glib to make 'hello world' code. Absolute minimum is:
    Pin1 - GND
    Pin2 - Vcc
    Pin4 - CS
    Pin5 - MOSI
    Pin6 - SCK
    Pin19 - 150ohm resistor to Vcc
    Pin20 - GND
    You do not need pot for contrast as shown in some setups.


    I recommend this product
