Coughsense: common questions

What microcontroller does the Coughsense use?

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

How big is the Coughsense PCB?

The Coughsense measures 35.2 × 59.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Coughsense?

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 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 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 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.
