The motor is driven by an exclusive circuit, and a reference circuit is shown below.
When the motor stops working and the VIB_DRV_N is disconnected, the redundant electricity on the
motor can be discharged from the circuit loop formed by diodes, thus avoiding damage to components.
3.18. LCM Interface
SC200R series module provides one LCM interface, which is MIPI_DSI standard compliant. The interface
supports high-speed differential data transmission and supports HD+ display (1440 × 720 @ 60 fps). The
pin definition of the LCM interface is shown below.
