Pros:
This is cheapest GLCD that i found.
Cons:
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.
Other:
After lot of time wasted this is ST7920. Wiring for 5V supply is here http://renoirsrants.blogspot.com/2013/02/hello-world.html. 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.
Bottomline:
I recommend this product
