Its main chip is the XIAO-ESP32-S3 (SKU 113991054), from the ESP32 family. Other key parts include the AP2112K-3.3TRG1, MCP1653S-E/UN and MAX3232CDR. By type, the board carries 14 capacitors, 14 resistors, 11 diodes, 5 connectors, 4 ICs and 3 fuses.

It belongs with the iot & wireless and power & battery designs in this gallery.

From the project

Autonomous underwater sound velocity profiler — ESP32-S3, Valeport miniSVS, Bar30, 4-layer PCB

Projet #4018 — Sound Velocity Reel · Iter Systems · La Motte-Servolex, France

- Overview - Hardware - Firmware v3.4 - Hardware Debugging - Repository Structure - Documentation - Author

SV-Profiler builds depth-indexed sound velocity profiles in underwater environments. Unlike point measurement tools that give a single reading, the system continuously pairs sound velocity samples from a Valeport miniSVS sensor with depth readings from a Bar30 pressure sensor as the device descends or ascends through the water column.

SV-Profiler: common questions

What microcontroller does the SV-Profiler use?

The SV-Profiler is built around the XIAO-ESP32-S3 (SKU 113991054), from the ESP32 family.

How big is the SV-Profiler PCB?

The SV-Profiler measures 85 × 27 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SV-Profiler?

53 components, from 40 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the SV-Profiler design files?

From the mostapha73-rgb/SV-Profiler repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the SV-Profiler design in my own project?

The repository has no license, so all rights stay with mostapha73-rgb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SV-Profiler without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
