SparkFun (PID 14539) Distance Sensor Breakout - RFD77402 (Qwiic)
Product Description
SparkFun (PID 14539) Distance Sensor Breakout - RFD77402 (Qwiic)
- RFD77402 3D ToF (Time of Fly) sensor module
- Measurement Range: ~50mm to 2,000mm Precision: +/-10% Light Source: 850nm VCSEL
- Field of View: 55° Field of Illumination: 23° Max Read Rate: 10Hz (We’ve seen up to 20Hz in practice)
- I2C Address: 0x4C
- Operating Voltage 3.3V Current 7 mA average at 10Hz
Thanks to the RFD77402's 850nm VCSEL and electronic driver and optical receiver sensor, this breakout is ideal for distance measurements ranging from 100mm to 2000mm, 1D gesture recognition, obstacle detection and avoidance in robotics applications, and more! The RFD77402 utilizes an I2C interface that supports a direct 8-bit addressing scheme to access the module user's register set and an additional 16-bit indirect addressing scheme that is mainly used for debugging purpose or special operations.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
Note: CLASS 1 LASER PRODUCT CLASSIFIED IEC 60825-1 2014.
