NHD-3.12-25664UC with Arduino

Beretas Workshop
Hello, I have bought the nhd 3.12 25664ucy2 display and i have tried to turn it on using the example code in your site and the 4 wire interface connection with arduino nano and arduino uno but it doesn't work. I would appreciate it if you could help me to turn on the display and finish my project. Thank you in advance.

    Hi Beretas,

    The Arduino Uno has a 5V regulator, can you confirm if you are using a 5V regulator? This part is to be powered on with 3.3V.  Please reach out to us at nhtech@newhavendisplay.com for further support.
