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 A2 takes the 3.3V-TTL serial port (UART) as the communication

interface. The table below shows the transmission speed and the protocol

standard.

Note: the RX input signal of A2M4 is current control type. In order to

ensure the reliable signal identification inside the system, the actual

control node voltage of this pin will not be lower than 1.6v.

Scanner Motor Control

The RPLIDAR A2 is embedded with a motor driver which has speed tuning feature.

Users can control the start, the stop and the rotating speed for the motor via

MOTOCTL in the interface. MOTOCTL can be supplied using PWM signal with

special frequency and duty cycle, and in this mode, the rotating speed is decided

by the duty cycle of the input MOTOCTL PWM Signal.
