MicroPython LCD Display Project

This project demonstrates how to use a JC3248W535 LCD display with MicroPython.

Hardware

We're using the JC3248W535 LCD display, which is compatible with MicroPython. This display offers a good balance of size and resolution for embedded projects.

The JC3248W535 is a versatile LCD that can be easily integrated with MicroPython-capable microcontrollers like ESP32.

Features

• ESP32-S3 3.5-inch capacitive touch IPS module 8M PSRAM 16M 320*480
• Compatible with MicroPython
• Model: JC3248W535
• LCD: axs15231b QSPI
• TOUCH: axs15231b I2C
