LORDWORLD 2.8inch Touch Screen Expansion for Raspberry Pi CM4 development board
A 2.8 inch fully laminated touch screen with 5-point capacitive control and 6H toughened glass, adding USB 2.0 and Gigabit Ethernet to a Raspberry Pi CM4 development board
- 8-inch fully laminated display with 5-point capacitive touch for responsive interaction
- 6H toughened glass panel protects the screen from everyday knocks and scratches
- USB 2.0 interface connects directly to Raspberry Pi CM4 for simple integration
- Gigabit Ethernet port provides wired network access for headless or remote deployments
- Designed for Raspberry Pi CM4 projects and industrial IoT edge applications
Purpose and Audience
The LORDWORLD 2.8inch Touch Screen Expansion is an IoT edge device designed for Raspberry Pi Compute Module 4 development. It suits makers and engineers building compact projects that require an integrated display and touch interface. Buyers who need a larger screen or a non-touch panel should look elsewhere.
Thermals, Noise and Power
The board draws power through the USB 2.0 interface from the host Compute Module 4. It has no active cooling components, so it runs silently and adds minimal thermal load to the system. Power consumption scales with display brightness and touch activity.
Deciding Specification
The 2.8 inch fully laminated display with 5-point capacitive touch and 6H toughened glass is the defining feature. This specific screen size and touch capability determine whether the expansion fits your enclosure and interaction requirements.

이 상품에 대한 질문
How do I attach the 2.8inch touch screen to the CM4 development board and what alignment mistake should I avoid?
Align the board's connector with the CM4's expansion header and press evenly until seated; the common error is offsetting the pins by one row, which bends contacts and prevents boot.
What upkeep will the 5-point capacitive touch panel and 6H toughened glass need over time?
Clean the glass with a microfibre cloth and isopropyl alcohol; avoid abrasive pads that can wear the oleophobic coating and reduce touch sensitivity.
Which bottleneck appears first when the USB2.0 interface runs sustained data transfers?
The USB2.0 link limits continuous throughput, so large file copies or streaming workloads will saturate the bus before the compute module reaches its own ceiling.
