With it, you can create sophisticated in-air SONAR ToF systems or drive nearly any in-air or in-water transducer between 40-1000 kHz. Perfect for retrofitting older boat echosounders, experimenting with depth and fish-finding technologies, or even powering sidescan transducers to uncover what’s hidden on the seafloor.
This starter kit provides a solid starting point to get your first results in air. To use it's full potential in water, you need an in-water trandsucer (see GitHub repository). The software is built by the community, and already provides you with a well working Python interface (MAC, Linux and Windows) that lets you see raw echo column data, send NMEA sentences via TCP to navigation software and experiment with rendering options.
You can also run the TUSS4470 Arduino setup in UART/USB NMEA0183-only mode. This mode is recommended, if you want to get NMEA data into a Pixhawk or navigation software running on your computer.
You’ll find all the code and a detailed getting-started guide in the Getting Started Guide.
Please note: this isn’t a finished consumer device. It’s a development platform created for engineers, researchers, and advanced hobbyists who want to dig deeper into the capabilities of the TUSS4470 ultrasonic driver, evaluate different transducers, or prototype their own SONAR-based hardware.
