The Logic Level converter is connected to the Atmega328p and to the
84x48 LCD Display. The operating voltage for 84x48 LCD Display is 3.3V
and for Atmega328p it is 5V, so the Logic Level Converter is needed to
prevent damaging the devices.
For those who want to know more about the devices or look for an example
sketch, there is a Quick Start Guide for 84x48 LCD Display on our AZ-
Delivery website.
