 +**Core Product Comparison**
 +
 +Waveshare offers several versions to match different distances and environmental requirements: 
 +
 +^Model^Range^Accuracy^Interface^Best For|
 +|Standard TOF|0.01 – 5m|±1.5cm|UART / CAN|Indoor robots, obstacle avoidance|
 +|TOF (B)|0.10 – 15m|±2%|UART / I2C Long-range indoor/outdoor use|
 +|TOF (C)|0.05 – 25m|±3cm|UART / I2C|Outdoor navigation, material levels|
 +|TOF (D)|0.05 – 50m|±3cm|UART / I2C|Extreme long-distance detection|
 +|TOF Mini|0.02 – 7.8m|±4cm|UART / I2C|Ultra-compact builds (1g weight)|
 +
 +**Key Technical Features**
 +
 +  * **Cascading Support:** Up to 8 sensors on UART and 7 on CAN can be connected in series to a single bus, each assigned a unique ID.
 +  * **High Ambient Light Resistance:** Most "B," "C," and "Mini" models resist up to 100K LUX, making them functional in direct sunlight.
 +  * **Configurable FOV:** The standard model offers an adjustable Field of View (15° to 27°), while long-range models feature a narrow FOV (1° to 2°) to minimize interference.
 +  * **Integrated Processing:** Includes an embedded MCU and ranging algorithm, providing filtered distance data rather than raw phase shifts.
 +  * **Software Tools:** Waveshare provides a PC Assistant Software for real-time waveform monitoring, configuration, and data recording.
