Description
This is a screen for advanced hackers who like the look of a nice, round TFT screen with tons of pixels. The 2.8″ diagonal-sized display has 480×480 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’ 800×480 or 480×272 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 does not have a touchscreen. 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!
