 For Model A3M1 Only
Figure 2-7 RPLIDAR Power Supply Specification
Data communication interface
The RPLIDAR A3M1 takes the 3.3V-TTL serial port (UART) as the communication
interface. The table below shows the transmission speed and the protocol
standard.
Figure 2-8 RPLIDAR Serial Port Interface Specifications
Note: the RX input signal of A3M1is 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.
