Benewake TFS20-L LiDAR dTOF ranging module

Benewake’s TFS20-L is a fully integrated, single-channel, direct time-of-flight (dToF) ranging mini-module for service robots, consumer drones and Internet of Things (IoT) applications.

The single-point LiDAR module features a compact, lightweight design that incorporates a sensitive infrared-enhanced, single photon avalanche diode (SPAD) sensor with a range of up to 20 m for high-precision distance measurement under difficult lighting conditions. Many dToF sensors on robots only detect obstacles on a horizontal plane and are ineffective at detecting obstacles below the horizontal plane.

The product is designed to provide precise measurement data for surfaces with different reflectivity. It offers a sunlight resistance of 15 m at 100 Klux and a reflectivity correction feature. It also utilises a fully integrated SPAD chip solution, a histogram statistical algorithm, and a fast time-to-digital converter (TDC) architecture for stable and efficient operation.

The module supports I²C and UART interfaces and operates on a single 3.3 V power supply with built-in temperature compensation. Its compact size, lightweight design, long-range measurement capabilities and good distance measurement performance under strong ambient light make it suitable for miniature dToF applications.
