AirQualityHoboken: common questions

What microcontroller does the AirQualityHoboken use?

The AirQualityHoboken is built around the CP2102N-A02-GQFN24, from the ESP32 family.

How big is the AirQualityHoboken PCB?

The AirQualityHoboken measures 63.3 × 41.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AirQualityHoboken?

49 components, from 28 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 AirQualityHoboken design files?

From the JokerIsMyBae/AirQualityHoboken 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 AirQualityHoboken design in my own project?

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

Can I test firmware for the AirQualityHoboken 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.
