Figure 2-7 RPLIDAR Power Supply Specification
Note: When the lidar is connected to the power supply, there is a process of
charging the input capacitor. The maximum transient current of charging can
reach 2500mA. After stable operation, the working current does not exceed
600mA.
Data communication interface
The RPLIDAR S2 takes the 3.3V-TTL serial port (UART) as the communication
interface. The table below shows the transmission speed and the protocol
standard.
