The integrated Resistive Touch panel enables the display to function with the Raspberry Pi without the need for a mouse or an alternative HMI device.
The 4DPi-24-HAT is designed to work with the Raspbian Operating System and is powered directly off the Raspberry Pi’s 40-way header requiring no external power supply and allows effortless touch-based interaction with the Raspbian Operating System. The display has a typical framerate of 25 frames per second, which can be increased with kernel compression.
The display’s backlight can be turned on or off using an on-board jumper or dimmed using PWM controls. The on-board EEPROM allows for quick identification of the 4DPi-24-HAT by the Raspberry Pi. The 4DPi-24-HAT is compatible with Raspberry Pi A+, B+ and Raspberry Pi 2 and is fully HAT Standard compliant
