Four-dimensional systems There are touch and non-touch versions of Raspberry Pi RP2350 display modules available for embedded applications.

The display modules come in eight different sizes, ranging from 2.4 to 9.0 inches, and resolutions, ranging from 240 x 320 pixels to 800 x 480 pixels. They are certified “Powered by Raspberry Pi” and use the dual-core architecture and security capabilities of the Raspberry Pi RP2350 to create “secure, professional-grade applications that require modern UI.”

4D Systems is renowned for producing top-notch displays for programmers wishing to construct complex embedded system user interfaces. For every gen4-RP2350 display module, there are four different types of touch panels available: capacitive, resistive, capacitive with a cover lens bezel (CLB), and non-touch. In order to connect a motherboard or auxiliary board, the gen4-RP2350 series also has a 30-pin FPC/ZIF socket that can accommodate a 0.5mm pitch FFC.

The gen4-RP2350 display series works with the Workshop5 IDE from 4D Systems, which is based on the application-specific libraries and the Raspberry Pi Pico SDK. According to 4D Systems, because of the new series’ distinct design, the code created for the company’s earlier modules would not function on it. Nonetheless, physical compatibility with other Gen 4 display modules is maintained.
