## Description

The BigTreeTech Pi TFT43 V2.0 is a 4.3-inch 800x480 IPS capacitive touchscreen expansion designed to pair directly with the BTT Pi, CB1, CB2, or Raspberry Pi CM4 compute modules. The display uses the DPI (Display Parallel Interface) protocol over the 40-pin GPIO header, providing a high-bandwidth connection for smooth rendering. Touch input is handled by the GT911 capacitive controller via I2C.

The display supports rotation (0°, 90°, 270°) and is configured through the Armbian/Debian OS via device tree overlays. It is purpose-built for the KlipperScreen graphical user interface, giving users a clean touchscreen panel for monitoring and controlling 3D printer operations directly on the control board.

The board is compact and designed to stack directly on compatible BIGTREETECH carrier boards. No additional PCB or wiring is required beyond the standard 40-pin connector. Hardware design files are available on GitHub under an open-source license.
