4D Systems developed touchscreen display starter kits for the Raspberry Pi that enable quick and easy wiring interface for portable and low power Raspberry Pi projects and applications. The starter kits for the 2.8-inch uLCD-28PTU-PI and 4.3-inch uLCD-43PTU-PI modules will be distributed by RS Components.

A unique aspect of the kits is the 4D Pi Adapter Shield, which connects to the serial GPIO port on the Raspberry Pi and to the touchscreen display module via a 5-way cable. The Adapter Shield also replicates the Raspberry Pi GPIO lines and allows users to gain easy access to other Raspberry Pi functions.

These displays deliver a human-machine interface solution for Raspberry Pi applications that features resistive-touch capability, on-board audio amplifier and speaker, and resolutions of 480 x 272 pixels and 240 x 320 pixels for the 4.3- and 2.8-inch screens respectively.

Each starter kit contains: a 4D serial Pi adaptor shield; a 2GB microSD card; a uUSB-PA5 programming adaptor; a 150mm 5-way female-female jumper cable for quick connection to another device or a breadboard; a 5-way male-male adaptor to convert the cable to male-female; and a quick-start user guide. A series of ViSi-Genie application software libraries are also available to communicate with the Raspberry Pi board and user code.
