Adafruit Qualia ESP32-S3 for TTL RGB-666 Displays

Experience vibrant visuals with the Adafruit Qualia ESP32-S3, the first cost-effective microcontroller capable of driving large TTL displays. Equipped with a 16 MB Flash and 8 MB octal PSRAM, it delivers seamless graphics, images, animations, or video at around 30 frames per second.

This development board supports the versatile 40-pin RGB-666 connector, used for square, round, and bar displays. It also includes capacitive touch overlay compatibility via its wired I2C port. The board's design integrates 16 pins for 5-6-5 RGB color output along with HSync, VSync, Data Enable, and Pixel Clock.

• Compatible with RGB-666 pinout displays.
• Features a constant current backlight control circuit with 25mA-200mA configurability.
• Powered via USB-C, with a dedicated hardware UART TX pin for debugging.
• Utilizes a PCA9554 I/O expander for initialization and control of displays.
• Includes two right-angle buttons and backlight control through the expander.
• Offers a Stemma QT / Qwiic port for sensor or device integration.

Pre-verified compatible displays include the 2.1" 480x480 round with or without touch, the 4" 720x720 square with touch, and the rectangular 4.6" 960x320 bar. Take your display projects to new heights while enjoying the flexibility of Arduino or CircuitPython programming as you develop alongside these digital innovations.
