3.2 Inch Primary Display for Raspberry Pi

The 4DPi-32 is a 3.2 Inch Primary Display for the Raspberry Pi, which plugs directly on top and displays the primary output like what is normally sent to the HDMI or Composite output. It features an integrated Resistive Touch panel, enabling the 4DPi-32 to function with the Raspberry Pi without the need for a mouse.

Communication between the 4DPi-32 and the Raspberry Pi is interfaced with a high speed 48Mhz SPI connection, which utilises an on-board processor for direct command interpretation and SPI communication compression, and features a customised DMA enabled kernel. This combination allows this display to output 25FPS when displaying a typical image/video, and can achieve higher depending if the image can be compressed.

The 4DPi-32 is designed to work with the Raspbian Operating System running on the Raspberry Pi, as that is the official Raspberry Pi operating system.

The 4DPi-32 features a breakout header (P2), which enables all of the Raspberry Pi GPIO pins to be accessed while the 4DPi-32 is connected. These can be access with jumper wires or with an IDC ribbon cable.
