Power Supply Interface
RPLIDAR S1 takes the only external power to power the range scanner core and
the motor system which make the core rotate. To make the RPLIDAR S1 work
normally, the host system needs to ensure the output of the power and meet its
requirements of the power supply ripple.

Data communication interface
The RPLIDAR S1 takes the 3.3V-TTL serial port (UART) as the communication
interface. The table below shows the transmission speed and the protocol
standard.
