AirResMask: common questions

What microcontroller does the AirResMask use?

The AirResMask is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the AirResMask PCB?

The AirResMask measures 50 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AirResMask?

43 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the AirResMask design files?

From the DigitalRealitiesLab/AirResMask repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the AirResMask design in my own project?

Yes, under the terms of its MIT license, which DigitalRealitiesLab chose for the repository.

Can I test firmware for the AirResMask 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.
