HearingAid RightV3: common questions

What microcontroller does the HearingAid RightV3 use?

The HearingAid RightV3 is built around the ESP32-S3, from the ESP32 family.

How big is the HearingAid RightV3 PCB?

The HearingAid RightV3 measures 18.3 × 16.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HearingAid RightV3?

19 components, from 16 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 HearingAid RightV3 design files?

From the AveryLion03/HearingAid 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 HearingAid RightV3 design in my own project?

The repository has no license, so all rights stay with AveryLion03. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the HearingAid RightV3 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.
