TFmini LiDAR Module (I²C)

1. Product Overview

Coupled with unique optical and electrical design, the product is based upon ToF (Time of Flight)

and adopts 850nm infrared light source so as to measure distance with stability, precision, high

sensitivity, and high speed.

The product is built with algorithms adapted to various application environments so as to offer

excellent distance measurement performances with low cost and small size. The product adopts

multiple adjustable configurations for flexible use by the client, which is better to satisfy the

end-users’ demand.
