# Benewake TFS20-L Mini Lidar

> Benewake TFS20-L is a 21 × 15 × 7.87 mm, 1.35 g single-point dToF lidar (VCSEL + SPAD). It ranges 0.2–20 m at 90 % reflectivity (15 m in 100 klux) and 12 m at 10 %, with ±6 cm to 6 m and 1 % beyond, and runs at 0–250 Hz (100 Hz default). It talks 3.3 V UART (115200) or I2C (0x10) on a 0.8 mm 6-pin connector, needs 3.3 V ± 9 % at ≤ 0.43 W, and has a < 2° FoV.
