The Story
This is a screen for advanced hackers who like the look of a loooooooong rectangular bar TFT screen with tons of pixels. The 3.7" rectangular display has 240 x 960 18-bit full-colour pixels and is an IPS display, so the colour looks great up to 80 degrees off-axis in any direction.
This version does not have a touchscreen.
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 x 480 (4.3", 5" or 7") or 480 x 272 (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. Also, to make this even more exciting as a display, the internal memory is set up as 360 x 960, but the leftmost 120 pixels are considered overscan and don't show up.
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!
