1. Product Description
TFmini Plus is a milestone of Benewake in the process of promoting the cost-effective -LiDAR.
Apart from low-cost, small-size and low-power-consumption, TFmini Plus also improves the
frame rate, introduces IP65 enclosures and optimizes various compensation algorithms. These
new characters greatly expand the application fields and scenarios of TFmini Plus.
