LORDWORLD 5" Touch Screen Expansion Base for CM4, Gigabit Ethernet, PoE Header

SKU CH-DV1A-EZ2WT

A 5-inch 800×480 IPS touchscreen base for CM4 adds gigabit Ethernet, a PoE header and 4K 30fps HDMI output

  • Sharp 5-inch 800 × 480 IPS display for clear details
  • Wide viewing angles with natural colour reproduction and fast response
  • Smooth five-point capacitive touch without ripple or pressure
  • Adjustable backlight brightness by software for day or night use
  • 4K 3840 × 2160 at 30 fps output via HDMI for external screens

5-inch Touch Base for CM4

This expansion base adds a 5-inch 800 × 480 IPS touchscreen to a Raspberry Pi Compute Module 4. It provides Gigabit Ethernet with a PoE header for network power options. The board suits developers building embedded HMIs, kiosks or portable test rigs that need local display and wired connectivity in one module.

Sustained Load Behaviour

The IPS panel maintains wide viewing angles and consistent colour during continuous operation. Capacitive touch remains responsive without ripple during extended use. Software-controlled backlight dimming reduces heat and power draw for long-running or battery-backed deployments. HDMI output drives a 3840 × 2160 external display at 30 fps for dual-screen workloads.

Upgrade Path and Limits

This base replaces a headless CM4 carrier when a built-in touchscreen and wired Ethernet are required together. It is not for projects needing more than 5-point touch, higher panel resolution or integrated wireless radios. The jump is worth it when a compact all-in-one touch interface simplifies enclosure design and cabling.

Questions about this item

How much power does the 5-inch 800 × 480 touchscreen and Gigabit Ethernet draw when the CM4 runs continuously?

The board includes a PoE header for Power over Ethernet; actual consumption depends on the CM4 module fitted and the backlight level set in software.

Which Raspberry Pi Compute Module 4 variant is required for the HDMI port to output 3840 × 2160 at 30 fps?

Any CM4 with wireless or non-wireless option works; the carrier routes the HDMI signals directly from the module's SoC.

Will the 5-point capacitive touch panel and Gigabit RJ45 work with a first-generation Compute Module?

No, the expansion base is designed exclusively for the Compute Module 4 form factor and pin-out.
