Communication interface
The RPLIDAR S2 uses separate 5V DC power for powering the range scanner core
and the motor system. And the standard RPLIDAR S2 uses XH2.54-5P male socket.
Detailed interface definition is shown in the following figure:

Power Supply Interface
RPLIDAR S2 takes the only external power to power the range scanner core and
the motor system which make the core rotate. To make the RPLIDAR S2 work
normally, the host system needs to ensure the output of the power and meet its
requirements of the power supply ripple.
