The TinyF laser ranging module is based on a D-TOF single-point laser sensor, an onboard MCU, and a housing. It features built-in sunlight rejection and anti-cover contamination algorithms, enabling accurate and rapid distance measurement. Even in extremely bright ambient light (100-190K Lux), it can accurately measure even the smallest objects, unaffected by variations in reflectivity, achieving precise ranging of 2m to 4m.

5. Notes
The test frame rate is 30Hz, with the FOV facing a standard reflector and no obstructions in front.
Refer to the above test conditions. Changes in test conditions may cause variations in measurement results.
The module's factory default frame rate is 30Hz; a firmware update is required to adjust to 90Hz.
Due to continuous product updates and improvements, this specification is subject to change. Please refer to the latest version for accuracy.
