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.

Max range is the printed figure at the stated target reflectivity; accuracy is the typical datasheet value. Scan frequency is the default rotation or frame rate.
Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
