4" Capacitive Touchscreen AV Control Panel with PoE & Android 11 New

The KanexPro CR-TOUCH4A is a 4-inch capacitive touchscreen control panel running Android 11, designed to replace traditional button keypads and expensive proprietary touch controllers in conference rooms, classrooms, and smart office environments. Powered by an ARM Cortex-A55 processor with 4GB DDR4 RAM and 32GB eMMC storage, it delivers a fully customizable graphical interface for AV device control via TCP/IP, HTTP, UDP, WebSocket, and RS232 — all from a standard 86 wall box.

The CR-TOUCH4A operates in dual mode: as a standalone touch screen central controller or as a user terminal connected to a host system. Its 720×720 high-resolution display provides intuitive touch-based room control for source switching, volume adjustment, lighting scenes, and display power. Gigabit Ethernet with PoE support enables single-cable installation, while the built-in RS232 port handles legacy serial device control. Programming is handled through EASYAccomplish software available for Windows, Mac, and iOS, with web GUI access for network configuration. For US installations, a surface-mount 86 box adapter or retrofit plate would be needed since US standard gang boxes have different screw spacing.
