Lcm Interfaces - Quectel Smart Module Series Hardware Design

The vibrator is driven by an exclusive circuit, and a reference circuit design is shown below.

3.18. LCM Interfaces

Based on MIPI DSI standard, the video output interfaces (LCM interfaces) of SA800U-WF support
2560 × 1600 @ 60 fps VESA DSC 1.1 primary display with 4 lanes. Additionally, with a MIPI to HDMI
converter (LT9611 is recommended), its 8 lanes can support QUXGA display (resolution: 3840 × 2160).
The module supports dual-LCD independent display: default - DSI + DP (over USB Type-C), optional -
DSI0 + DSI1. Please note that DSI1 does not support screens with command mode.
