2.4 ” gen4 Intelligent Display Module with ESP32 SoC

The gen4 – ESP32 2.4” Integrated Display Module is part of the latest gen4 – ESP32 series of modules Designed and Manufactured by 4D Systems.

The available 2.4″ display modules are 240×320 resolution IPS TFT LCD Displays offering an SPI Interface between the ESP32-S3R8 Processor. Available in Non-Touch, Capacitive Touch, and Capacitive Touch with Cover Lens Bezel (CLB).

The ESP32-S3R8 Processor makes available multiple GPIO which include UART, SPI, I2C, PWM, and Analog functionality, while also serving interfaces for the LCD Touch screen, Quad SPI Flash, microSD Card, and Native USB-C.

The user interface to the gen4-ESP32 series is a 30-pin FPC/ZIF socket, designed for a 30-way 0.5mm pitch FFC cable, for easy and simple connection to an application or motherboard, or for connecting to accessory boards for a range of functionality advancements.

This series of boards is compatible with the 4D Systems Workshop4 IDE, utilizing the Espressif compiler and 4D Systems purpose-built libraries, allowing a feature-rich design and programming experience.

Any code designed and written to run on other 4D Systems display modules, such as modules featuring Goldelox, Picaso, Pixxi, or Diablo16 Graphics Processors, are unfortunately not compatible with the gen4-ESP32 range due to being a totally different processor family. However, please contact 4D Systems Support Team for assistance if you are planning on migrating from a different 4D Systems display model, as there are some similarities between them – such as the graphics, however, a majority of the coding will have to be adapted.

From a mechanical perspective, these gen4-ESP32 modules are physically the same mounting size as other gen4 products by 4D Systems. The only difference is the circuitry used. The overall thickness of these gen4-ESP32 modules is greater than other gen4 products, due to the USB-C connector. Typically wherever a different gen4 module had been mounted, a gen4-ESP32 module could fit in the same location.
