From the project

All CAD pdfs and RAW files from KiCAD6 and some nice pin mapping references + block diagrams. Custom symbol and footprint library (not provided) needed to rebuild Gerbers (provided as-is).

All CAD pdfs and RAW files from KiCAD6 and some nice pin mapping references + block diagrams. Custom symbol and footprint library (not provided) needed to rebuild Gerbers (provided as-is).

Contains schematic, PCB, BOM (entire KiCAD project + PDF prints) and Gerber files for 3x 4 layer mixed signal PCBs. KiCAD project has since seen edits in silkscreen and rectifying some issues with DNP parts.

Ultrasonic Sound Steering - Control Rev. A: common questions

What microcontroller does the Ultrasonic Sound Steering - Control Rev. A use?

The Ultrasonic Sound Steering - Control Rev. A is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Ultrasonic Sound Steering - Control Rev. A PCB?

The Ultrasonic Sound Steering - Control Rev. A measures 117 × 99.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ultrasonic Sound Steering - Control Rev. A?

377 components, from 85 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 Ultrasonic Sound Steering - Control Rev. A design files?

From the kharper55/soundSteering_CAD_FINAL 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 Ultrasonic Sound Steering - Control Rev. A design in my own project?

The repository has no license, so all rights stay with kharper55. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ultrasonic Sound Steering - Control Rev. A 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.
