About the AirQualityBoxy PCB

AirQualityBoxy is an open source ESP32 PCB design by fablabnk, published on GitHub. It is a board, with 5 components from 5 distinct parts.

Its main chip is the ESP32-C3_SUPERMINI_TH, from the ESP32 family. Other key parts include the CCS811_Gas_Sensor, 128x32_OLED_Display_Breakout and USB_C_Power_Data_Breakout. By type, the board carries 4 ICs and 1 buzzer.

It belongs with the sensors, displays & leds and dev boards & breakouts designs in this gallery.

AirQualityBoxy: common questions

What microcontroller does the AirQualityBoxy use?

The AirQualityBoxy is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How many components are on the AirQualityBoxy?

5 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the AirQualityBoxy design files?

From the fablabnk/AirQualityBoxy repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the AirQualityBoxy design in my own project?

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

Can I test firmware for the AirQualityBoxy 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.
