We reported on Australian company 4D Systems from the Embedded World event last year (Embedded World 2017 – Round Up). Now the company has released through its European distribution, a range of three new modules for use directly with the Raspberry Pi subsystem.
The display modules offer either resistive or capacitive touch controls and are powered directly from the Raspberry Pi. Modules in the range come in three screen sizes – 4.3″, 5.0″ and 7.0″. The devices connect to the Raspberry Pi through a 30 pin FPC cable and an adaptor board that conforms to the Raspberry Pi expansion header pin-out and Pi’s HAT device identification standard. The two larger units have 800 x 480 resolution, while the smaller one is 480 x 272. Typical frame rate is 20 fps for the smaller display, 7fps for the others and higher if the image can be compressed.
The new units in the gen4-4DPi range bring the total number of displays that the company has for the Pi to 17.
