9.0″ Intelligent Display Module with ESP32 SoC

The ESP32 9.0” Integrated Display Module is part of the latest ESP32 series of modules Designed and Manufactured by 4D Systems.

These ESP32-90 modules use an RGB Interface between the ESP32-S3R8 Processor, and the 800×480 resolution TFT LCD Displays. The displays are TN TFT LCD.

Available in Non-Touch, Resistive 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, Real Time Clock, Quad SPI Flash, microSD Card, 8bit IO Expander and Native USB-C.

The user interface to the ESP32-90 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 displays are compatible with the 4D Systems Workshop4 IDE, utilising 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 ESP32-90 range due to being a 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 ESP32-90 modules are physically the same mounting size as other 4D Systems uLCD 9″ modules, such as the Diablo uLCD-90D, uLCD-90DT, uLCD-90DCT and uLCD-90DCT-CLB, as well as the Pixxi-44 versions, uLCD-90P4, uLCD-90P4T, uLCD-90P4CT and uLCD-90P4CT-CLB. The only difference is the circuitry used. The overall thickness of these ESP32-90 modules is greater than the 4D Systems 9″ products, due to the USB-C connector and coin cell battery holder for the RTC. Typically wherever a uLCD-90 module had been mounted, an ESP32-90 module could fit in the same location.

Models in this size:

  • ESP32-90 (Non-Touch)
  • ESP32-90T (Resistive Touch)
  • ESP32-90CT (Capacitive Touch)
  • ESP32-90CT-CLB (Capacitive Touch, with Cover Lens Bezel)
