  • Hi there, I’m after buying this LCD for my son (9) who wants to use it with his raspberry pi to connect to a breadboard.
    Can you let me know what I would also need to connect this to the breadboard? Some kind of pins I’m guessing? But I’m not entirely sure what ones - any help gratefully received! Cheers

  • Is it the same one as this one :

  • Question - how hard is it to use these with a 4 pin data interface rather than 8?

  • I am having trouble getting any visible output out of this LCD. Tried a 9k pot to get a voltage divider to supply V0, and at could get no output at all. Using an arduino pro mini 3.3v in 4 bit parallel mode. No clear indication here whether this is the correct method for powering the LCD contrast pin, or whether negative voltage is required.

    • This is because of the following issues: 1. loose connection of the 10k trim pot resistor. 2. 0k. Adjust the trim pot resistor to higher value.

    • I was able to figure it out. It works just as it should: 10k pot for contrast just like any other LCD
