TideBand is a wrist-worn, dive-rated hydrographic instrument that measures and logs three-dimensional water-current velocity profiles in real time during underwater operations. It is designed for professional divers, marine biologists, underwater archaeologists, search-and-rescue teams, and offshore energy inspectors who need to understand local current shear, tidal flow direction, and turbulence intensity as they move through the water column — without surfacing to read a boat-mounted acoustic…

TideBand — Wrist-Worn Hydrographic Current Profiler: common questions

What microcontroller does the TideBand — Wrist-Worn Hydrographic Current Profiler use?

The TideBand — Wrist-Worn Hydrographic Current Profiler is built around the STM32H733VGT6, from the STM32 family.

How big is the TideBand — Wrist-Worn Hydrographic Current Profiler PCB?

The TideBand — Wrist-Worn Hydrographic Current Profiler measures 62 × 52 mm, has 5 copper layers and is 1.6 mm thick.

How many components are on the TideBand — Wrist-Worn Hydrographic Current Profiler?

24 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the TideBand — Wrist-Worn Hydrographic Current Profiler design files?

From the jayis1/hardware-design-lab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TideBand — Wrist-Worn Hydrographic Current Profiler design in my own project?
