Wild air quality monitor: common questions

What microcontroller does the Wild air quality monitor use?

The Wild air quality monitor is built around the ESP32-S3-DEVKITC-1-N8R2, from the ESP32 family.

How big is the Wild air quality monitor PCB?

The Wild air quality monitor measures 67.5 × 59.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wild air quality monitor?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wild air quality monitor design files?

From the ri-buni/Wild-air-quality-monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Wild air quality monitor design in my own project?

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

Can I test firmware for the Wild air quality monitor 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.
