DESCRIPTION
RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.
The SparkFun Distance Sensor Breakout utilises the RFD77402 3D ToF (Time of Flight) sensor module from Simblee to give you the most accurate measurements at short range. The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) module to measure the amount of time it takes to bounce off a target. This allows low-cost millimetre readings up to two meters! To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilising our handy Qwiic system. However, there is still broken out 0.1″ spaced pins in case you prefer to use a breadboard.
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 utilises 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.
