Yealink STAND-EXP43 EXP43 Color LCD Expansion Module

Overview :

The Yealink EXP43 is a color LCD expansion module designed to increase the functional capacity of compatible Yealink IP phones. It is primarily used by receptionists, administrative assistants, and power users who need to monitor and manage a large volume of calls simultaneously. By adding 60 programmable keys across three pages, it eliminates the need for complex menu navigation during high-traffic operations.

The module features a 4.3-inch color screen that provides a vivid visual interface for call status, speed dialing, and busy lamp field (BLF) monitoring. It is engineered for seamless integration into office and data-center environments where desk-phone scalability is a priority.

Deployment involves a simple daisy-chain connection to the host phone, which provides both power and data signaling. It is fully compatible with Yealink T43U, T46U, and T48U series phones. Note that this module requires a compatible host phone; it cannot function as a standalone device and is not compatible with older T4 series models lacking the required USB architecture.

Key Features :

• 4.3-inch 272×480 color screen for clear visual management.

• 20 physical keys with dual-color LED indicators for line status.

• Total of 60 programmable keys across three page views.

• Daisy-chain support for up to three modules on one phone.
