1. Description
The 4DPi-32-II (Revision 2.x Hardware) is a 3.2”
Primary Display for the Raspberry Pi* A+, B+, Pi2,
Pi3, Pi3 B+, Pi Zero and Pi Zero W 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-II to function with the
Raspberry Pi without the need for a mouse.
Communication between the 4DPi-32-II 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-II is designed to work with the
Raspbian Operating System running on the
Raspberry Pi, as that is the official Raspberry Pi
operating system. It is also compatible with Pixel.
Note: 4DPi-32-II Hardware states 4DPi-32 as the
part number, but is identifiable as the HW Rev of
the PCB is 2.0 or above.
Note*: Raspberry Pi is a trademark of the Raspberry
Pi Foundation, and all references to the words
‘Raspberry Pi‘ or the use of its logo/marks are
strictly in reference to the Raspberry Pi product,
and how this product is compatible with but is not
associated with the Raspberry Pi Foundation in any
way.
2. Features
• Universal 3.2” Primary Display for the Raspberry
Pi.
• Compatible with Raspberry Pi A+, B+, Pi2, Pi3,
Pi3 B+, Pi Zero and Pi Zero W Revision 2.x
hardware is not compatible with older A or B
models.
• 320x240 QVGA Resolution, RGB 65K true to life
colours, TFT Screen with integrated 4-wire
Resistive Touch Panel.
