A 4.3 inch TFT and ESP32-S3

by shedboy71

This LCD module uses an ESP32-S3-WROOM-1 module as the main controller, the main controller is a dual-core MCU, integrated WI-FI and Bluetooth functions, the frequency can reach 240MHz, 512KB SRAM, 384KB ROM, 8M PSRAM,Flash size is 16MB, The display resolution is 480*272 or 800*480, resistive touch or Capacitive touch.

The module includes an LCD display screen, backlight control circuit, touch screen control circuit . Reserve the TF card interface ,IO port interface, this module supports development in arduino IDE, ESP IDE, Micropython and Mixly.

ESP32-S3 is a low-power MCU-based system-on-chip (SoC) that supports 2.4 GHz Wi-Fi and Bluetooth®LowEnergy (Bluetooth LE).

It consists of high-performance dual-core microprocessor (Xtensa®32-bit LX7), a lowpower coprocessor, a Wi-Fi baseband, a Bluetooth LE baseband, RF module, and peripherals.

Software setup

To ensure the running environment, the same version is recommended.

All the projects are based on ESP32-S3 development board.

1.Install the Arduino IDE V1.8.19.

2.Install the ESP32 boards supporting V2.0.5

3.Click “Tools>Board>Boards Manager” to search for and install the ESP32 library:


A nice big LCD screen at a price of $27 which can be programmed using the Arduino IDE

A couple of examples are supplied via the links, the TFT comes with an sd card fitted
