New mouse-free touch display for the Raspberry Pi

4D Systems and element14 has launched the 4DPi-24-HAT, a 55mm, 320×240 pixel fully HAT standard compliant primary display with resistive touch that plugs directly on top of a Raspberry Pi. 

It displays the primary output of the Raspberry Pi, which is normally sent to the HDMI or Composite output. 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 frame rate 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.
