The Best Places to Buy Touch Display Module for Military Online and In-Store

Hosyond 4.0 Inches 480x320 TFT Touch Screen

These can work with 5V Arduinos, but they require 3.3V signals. Initially, I tried using the 2.4-inch version with NO voltage conversion, as I've had other 3.3V components that worked with 5V Arduinos before. This experiment, however, failed. I then attempted to use resistors to create a voltage divider to achieve approximately 3.3V, but this also didn't work. This could be due to an error on my part or perhaps a short, as having so many resistors on a breadboard increases the risk.

Ultimately, I decided to get the 3.5-inch version and utilized level shifters listed below. This approach worked well. While testing, I was not certain whether the 2.4-inch screen was damaged by the 5V. However, I swapped it directly with the 3.5-inch setup, and it functioned, indicating that although it doesn't work with 5V, it isn't necessarily destroyed by it either.

As of now, I have NOT tested the SD or Touch interfaces yet.
