This is a screen for advanced hackers who like the look of a nice, round TFT screen with tons of pixels. This massive?4″ diagonal-sized display has 720×720 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 (4.3″, 5″ or 7″) or 480×272 (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!
