DFR0299 - 8673144
For the on-board microphone module DFR0299 – 8673144, you’ll want to:
- Place it on the PCB’s edge, aligned with the enclosure’s mic opening so the capsule faces outward.
- Locate it away from high-current servo headers to minimize PWM noise coupling.
- Keep its analog input trace to the ESP32’s ADC pin as short as possible—ideally on the top layer—then return to the shared ground plane immediately.
- Surround it with a modest ground pour “island,” tying back to the main ground at a single point to reduce interference.
This positioning ensures clean audio capture and straightforward enclosure integration.

Reading docs about How to create a ground pour island around the microphone module in Flux.
This is the most relevant entry I found related to creating custom ground-pour islands:
“If you need more control over the shape of your copper areas beyond what standard copper fills provide, you should consider using polygons. Polygons allow you to create custom-shaped copper areas with precise control over their geometry. For detailed instructions on creating and working with polygons, refer to the Working with Polygons tutorial.”
Start polygon drawing
Assign polygon to GND
Add keep-out inside polygon
Adjust via stitching

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
