This impressive 4" IPS display has 720x720 16-bit full-color pixels, allowing advanced users to benefit from a visually stunning round TFT screen. The display's color remains vibrant up to 80 degrees off-axis in any direction.
The ST7701S driver supports both TTL RGB 'dot clock' data and SPI, though the latter is only for configuring the display. Note that the 40-pin connector doesn't fit the standard 800x480 (4.3", 5" or 7") or 480x272 (4.3") displays. This display is quite unique.
For powering up a display, one will need to use a microcontroller such as ESP32-S3 with octal PSRAM, or a computer like Raspberry Pi with either direct-DPI connection or an ICN6211. Neither of these can be connected to an Arduino or Feather.
This is just the display module! No PCB is included! Check out the Adafruit Qualia ESP32-S3 for TTL RGB-666 Display!
