4-Pin Connector
The L1 output cable is a 4-pin serial port, which can be connected to the L1 using the included con-
version module, power adapter, and data cable to realize power connection, control signal transmis-
sion, and data transmission. Users can also replace the conversion module with other cables ac-
cording to their own needs to improve the system's protection capabilities (such as water and dust
resistance).The specification of the serial port socket is GH1.25mm 4PIN.
The pin sequence definition of the L1's 4-pin serial port is as follows:
