Functional Description

The source states direct time-of-flight ranging and lists 200 Hz measurement frequency with 100, 50, 20, 10 and 1 Hz alternatives.

The source describes flexible installation and expansion for drone, sweeping-robot and industrial-robot integration.

Electrical Interface Definition

Signal names and directions are transcribed from the model source.

Pin	Signal	Source-stated function
1	NC (white)	Not connected
2	3.3V (red)	External power positive
3	TX / SCL (yellow)	Host RX / SCL
4	RX / SDA (green)	Host TX / SDA
5	NC (blue)	Not connected
6	GND (black)	External power negative
