When the motor stops, the redundant electricity can be discharged from the circuit loop formed by diodes,
thus avoiding component damages.
3.17. LCM Interface
SC20-WL module provides an LCM interface meeting MIPI DSI specification. The interface supports high
speed differential data transmission, with up to four lanes and a transmission rate up to 1.5Gbps per lane.
It supports maximally 720P resolution displays.
