Adafruit Industries Qualia ESP32-S3 for TTL RGB-666 Displays
Best controller for makers building high-resolution custom display projects.
Drive large, high-resolution TTL RGB-666 displays easily with the Adafruit Qualia ESP32-S3 development board. This board overcomes typical SPI limitations by leveraging the ESP32-S3's built-in peripheral and ample memory to handle displays lacking internal buffers. It features 16 MB of Flash and 8 MB of PSRAM, enabling near-instantaneous updates for graphics and video at around 30FPS. Designed for displays using the common 40-pin RGB-666 connector, it also conveniently wires touch overlay pins to the I2C port for integrated control. Note that the display unit itself is sold separately.

Know before you buy
No, the Qualia ESP32-S3 is a controller board only. You will need to purchase a compatible TTL RGB-666 display separately.
Standard ESP32 boards often struggle with high-resolution displays due to limited memory and lack of dedicated hardware. The Qualia ESP32-S3 uses the S3 chip's built-in display peripheral and 8MB of PSRAM to handle large buffers, allowing for smooth 30FPS updates that standard boards cannot achieve.
Yes. The board features a dedicated I2C port specifically wired to support touch overlay pins, making it straightforward to integrate touch functionality with your display.
This board is designed for displays that utilize the standard 40-pin RGB-666 interface, which is common for many high-resolution TTL panels.
Yes, the 8MB of Octal PSRAM is specifically included to provide the necessary memory for large image buffering, which is essential for maintaining high frame rates on high-resolution screens.
While it simplifies the complex task of driving high-resolution displays, it is best suited for users who have some experience with microcontroller development and are comfortable working with hardware interfaces and display drivers.
