SparkFun Qwiic dToF Imager Sensor - TMF8820, Time-of-Flight
The SparkFun Qwiic dToF Imager Sensor (TMF8820) is a high-precision direct Time-of-Flight distance sensor module featuring a 3×3 multi-zone detection grid. Operating at 3.3V with an I2C/Qwiic interface, it provides accurate ranging from 10mm to 5 meters, ideal for robotics, automation, and smart device integration.
Features
- Direct Time-of-Flight (dToF) technology with SPAD array and on-chip histogram processing for high accuracy.
- 3×3 multi-zone distance measurement output for enhanced spatial awareness and object tracking.
- Long detection range up to 5000 mm (5 meters) with a configurable field of view up to 63°.
- Integrated Class 1 940nm VCSEL light source with sunlight rejection filter for reliable operation in varied lighting.
- Plug-and-play Qwiic (I2C) connectivity and compact 26x26mm footprint for rapid prototyping and integration.

The SparkFun Qwiic dToF Imager Sensor leverages the ams OSRAM OSRAM TMF8820 system-on-chip, which integrates a Single-Photon Avalanche Diode (SPAD) array, Time-to-Digital Converter (TDC), and histogram processing engine. This direct Time-of-Flight (dToF) architecture measures the time for emitted 940nm VCSEL pulses to reflect off a target, enabling sub-centimeter precision distance measurements immune to ambient light interference.
The sensor outputs data as a 3×3 zone grid, providing not just distance but also basic spatial context for presence detection, object sizing, and simple gesture recognition. Its on-chip processing handles complex signal conditioning, delivering stable readings at up to 30 Hz. The module is designed for robust performance across an industrial temperature range from -30°C to +70°C.
Integration is streamlined via the Qwiic connector system, offering solderless I2C communication, while broken-out pins support direct connection to microcontrollers like Arduino, Raspberry Pi, and ESP32. The compact form factor and low standby current make it suitable for battery-powered and space-constrained applications.
