Connection Winstar WH1602B3-SLL-JWV 16x2 LCD VATN White on Black I2C Interface to Arduino UNO Answered

Hello,

I have some trouble with the connection of the Winstar I2C LCD to a Arduino Uno.

Can someone advise me?

In a pdf from Winstar there is a diagram (as attached), but I see a lot af pins that I don't know how to connect to a Arduino.

Thank you very much for your help.

Have you solved this issue with WH1602B3? I can't show any characters on this display. I query I2C address and get 0x3F, and 0x3C when 7 8 and 12 connected to gnd. But when I try to print nothing show up. I'm using 20K potentiometer, so contrast is not the issue.

You diagram is marked with 4SPI Interface. I've found this diagram for I2C
