My 12C/SPI LCD backpack for 3V-5V is Not Working!

I am communicating with 12C logic.

I am using a Standardized 20 by 4 LCD from Adafruit here:

I agree that it might be a good idea to not use the LCD backpack.

I didn’t know you can make it work without the LCD backpack.

I also was thinking of just using a new type of LCD such as a 12C LCD Display like this one:

It is usually used for breadboards but I can just solder it instead.
