AGS10-VOC-Monitor: common questions

What microcontroller does the AGS10-VOC-Monitor use?

The AGS10-VOC-Monitor is built around the XIAO-RP2040-SMD, from the RP2040/RP2350 family.

How big is the AGS10-VOC-Monitor PCB?

The AGS10-VOC-Monitor measures 99.8 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AGS10-VOC-Monitor?

24 components, from 13 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 AGS10-VOC-Monitor design files?

From the limiez1011/AGS10-VOC-Monitor 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 AGS10-VOC-Monitor design in my own project?

Yes, under the terms of its GPL-3.0 license, which limiez1011 chose for the repository.

Can I test firmware for the AGS10-VOC-Monitor without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
