Datasheet

The RFD77402 Simblee Internet of Things (IoT) 3D time-of-flight (ToF) sensor module from RF Digital is now being shipped by Mouser Electronics. The module is founded on the Simblee platform, which offers an end-to-end development environment for a variety of IoT applications from white goods and consumer and industrial measurement devices to gesture recognition and robotics.

The sensor module integrates an embedded light sensor, vertical cavity surface emitting laser (VCSEL) driver, microcontroller and onboard memory to provide highly accurate distance mapping and 3D imaging technology.

It uses the eye-safe laser to measure the amount of time it takes to bounce off a given target. The high-repeatability laser features an 850nm wavelength light source and offers an overall sensing distance from 100 mm up to 2 meters.

Designed specifically for applications requiring accurate distance mapping and 3D imaging using the sensor module’s ToF capabilities, the RFD77402 offers a10Hz maximum refresh rate and an I²C interface for device control and data transfer.

The sensor module is available in an ultra-small 4.8mm × 2.8mm × 1.0mm SMD package and is suited for a broad array of IoT sensor applications that require accurate distance measurement, user detection, obstacle detection and avoidance, gesture detection and recognition, directional movement and volume or height control.

For development in the Simblee ecosystem, the RFD77402 is supported by two development tools: the RFD77306 IoT 3D ToF shield and the RFD77804 Simblee Wireless IoT 3D ToF sensor kit.
