4D Systems Raspberry Pi RP2350 display modules come in touch and non-touch options for embedded applications

4D Systems, an Australian company specializing in intelligent display solutions, has released Raspberry Pi RP2350-powered display modules with touch and non-touch options.

The display modules are available in eight different sizes from 2.4-inch to 9.0-inch and different resolutions from 240×320 up to 800×480 pixels. They are “Powered by Raspberry Pi”-certified and leverage the Raspberry Pi RP2350’s dual-core architecture and security features for “secure, professional-grade applications that require modern UI”.

4D Systems is well-known for its high-quality displays designed for developers looking to create sophisticated user interfaces in embedded systems. There are four touch panel options for each gen4-RP2350 display module: non-touch, resistive touch, capacitive touch, and capacitive touch with a cover lens bezel (CLB). The gen4-RP2350 series also features a 30-pin FPC/ZIF socket to fit a 0.5mm pitch FFC for connecting a motherboard or accessory board.

We have already covered Waveshare’s RP2350-LCD-1.28 display module but the gen4-RP2350 display modules are the first RP2350-powered displays we have seen in larger size and form factor. We have also written about the 4Duino-24, another 4D Systems product, which is still sold today.

The gen4-RP2350 display series is compatible with 4D Systems’ Workshop5 IDE, built on the Raspberry Pi Pico SDK and 4D Systems’ application-specific libraries. 4D Systems states that the code written for other modules from the company will not run on the new series due to its different architecture. Physical compatibility is however retained with other gen4 display modules.

The gen4-RP2350 display modules are currently available for purchase, ranging from $39 for the 2.4-inch non-touch model up to $175 for the 9.0-inch capacitive with cover lens bezel model. The company also offers two kits, a connection kit and a starter kit, for $7 and $35, respectively. More information is available on the product page.
