TFMini - Micro LiDAR Module (Qwiic)
The TFMini is a compact Time-of-Flight (ToF) infrared rangefinder that measures distances from 30 cm to 12 m. At just 42 × 15 × 16 mm, it brings LiDAR-style ranging to projects traditionally limited to smaller sensors like Sharp GP-series infrared rangefinders — but with the accuracy advantage of ToF measurement instead of triangulation.
This Qwiic-enabled version includes a boost board with a Qwiic connector for easy I²C integration. Connect over 100 sensors on a single bus (each drawing approximately 800 mA, so size your power supply accordingly). For breadboard use, pick up a Qwiic Adapter.
Key Features
- 30 cm to 12 m Range – ToF distance measurement (varies with target reflectivity and lighting)
- Ultra-Compact – Just 42 × 15 × 16 mm
- Qwiic / I²C Interface – Solderless connection via included boost board
- Multi-Sensor Support – Connect 100+ sensors on a single I²C bus
- Time-of-Flight Measurement – More accurate than triangulation-based IR sensors
Specifications
- Measurement Method: Time-of-Flight (LED-based, not laser)
- Range: 30 cm – 12 m
- Interface: I²C (Qwiic)
- Current Draw: ~800 mA per sensor
- Dimensions: 42 × 15 × 16 mm (sensor module)
Tip: This sensor uses an LED and optics for ranging, not a laser — it's more accurately described as a Time-of-Flight infrared rangefinder. Effective range depends on target reflectivity and ambient light conditions.
