Qwiic_TOF_Module_RFD77402
A Qwiic-compatible time-of-flight distance sensor module using the RFD77402 IC for precise rangefinding up to 2 meters.
Overview
The Qwiic TOF Module (RFD77402) is a compact distance sensor board that uses time-of-flight technology to measure distances from 100mm to 2000mm. It's designed for easy integration into projects via the Qwiic connector system or standard headers, making it ideal for rapid prototyping and embedded applications.
Key Features
- Fast Distance Measurement — Uses a VCSEL laser and built-in detector to measure photon round-trip time with a 10Hz refresh rate
- Qwiic Connectivity — Features two Qwiic connectors for daisy-chaining with other I2C modules without soldering
- Compact Design — Includes snap-off mounting tabs to reduce board size when needed
- Eye-Safe Operation — Class 1 laser ensures safety for most applications
- Wide Application Range — Suitable for robotics obstacle detection, gesture recognition, proximity sensing, and IoT devices
Philosophy
The module emphasizes ease of use through the Qwiic ecosystem while maintaining flexibility for traditional prototyping methods, enabling both beginners and experienced makers to incorporate precise distance sensing into their projects.
