ESP32-S3 SPI 3.5" TFT with Touch

Introduction

The latest ESP32-S3 SPI TFT touch, features advanced core Xtensa® dual-core 32-bit LX7 and Bluetooth 5.0.Compares to the ESP32-S3 Parallel TFT with Touch, it takes much fewer pins of the ESP32-S3, so more pins can be reserved there, for application usage, such as connecting kinds of sensors, so this board can be used for applications such as local monitoring/display, and IoT connections to the cloud, for remote monitoring/controlling.

This 3.5" 320x480 TFT LCD driver is ILI9488, it uses standard SPI for communication with ESP32-S3, so the other IO of the controller can be used for external applications.
