This is a screen for advanced hackers who like the look of a nice, round TFT screen with tons of pixels. The 2.1" diagonal sized display has 480x480 16-bit full-color pixels and is an IPS display, so the color looks great up to 80 degrees off-axis in any direction.

The TFT driver is ST7701S and uses both SPI and TTL RGB 'dot clock' data. The SPI is only for configuring the display - you cannot draw pixels over SPI! Also, despite having a 40-pin connector, it does not have the same pinout as standard 'rectangular' 800x480 (4.3", 5" or 7") or 480x272 (4.3") displays. It's a new kind of beast for sure.

To make stuff light up you'll need a chip that can perform TTL RGB TFT driving, which means a powerful microcontroller such as the ESP32-S3 with octal PSRAM or a computer like a Raspberry Pi (with either direct-DPI connection or an intermediary chip like the ICN6211). Either way, it's not something you can wire up to your Feather or Arduino!

This display is not only round, it has a lovely bezel with capacitive touch display (CST826) with connection for I2C and IRQ on the 40-pin FPC. You can read the capacitive touch activity using our Arduino or CircuitPython libraries.

This is just the display module! No PCB is included.

You cannot use these with an everyday microcontroller unless it specifically has support for RGB-666 displays so please do not purchase unless you know for sure that it can plug into a driver board with the correct pinout as well. Check out the Adafruit Qualia ESP32-S3 for TTL RGB-666 Display!
