Coughsense panel: common questions

What microcontroller does the Coughsense panel use?

The Coughsense panel is built around the edison_iot_module, from the Raspberry Pi family.

How big is the Coughsense panel PCB?

The Coughsense panel measures 119.5 × 130.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Coughsense panel?

89 components, from 36 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 Coughsense panel design files?

From the lab11/CoughNote repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Coughsense panel design in my own project?

The repository has no license, so all rights stay with lab11. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Coughsense panel without the hardware?

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