The RPLIDAR A3 development kit contains standard RPLIDAR A3 unit (A3M1). The

RPLIDAR is embedded with logic IO drivable motor controller which can be used

to configure the scan frequency by tuning motor speed. Developers can also

choose to turn off the motor for power saving purpose.

RPLIDAR usage and interface definition will be introduced in the coming sections.

USB Adapter

The USB adapter comes with a dial switch. It can be used to switch the Baud rate

from 115200 to 256000 or vice versa, which is compatible with RPLIDAR A3 and

former RPLIDAR series. Please note that the Baud rate should be set as 256000 if

the USB adapter is connected with RPLIDAR A3..
