Figure 2-5 RPLIDAR External Interface Signal Definition
Note: the RX input signal of A1M8 is recognized by the current. 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.
Figure 2-6 RPLIDAR A1 External Interface Specifications
Note: The batch version is a non-development kit and does not include the
adapter board included in the development kit. For the motor interface and core
interface of batch version, they use the PH1.25-3P horizontal pitch connector and
PH1.25-4P vertical pitch connector respectively. The batch version does not
provide cables. Please refer to the mechanical dimensions in Chapter 5 for details
of signals and their matched pins. But the RPLIDAR development kit provides 1.25-
pitch 3+4pin to 1.25-pitch 7pin cable. Please refer to RPLIDAR Development Kit
