Gas sensor asm: common questions

What microcontroller does the Gas sensor asm use?

The Gas sensor asm is built around the STM32L031G6U6, from the STM32 family.

How big is the Gas sensor asm PCB?

The Gas sensor asm measures 41.3 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gas sensor asm?

65 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gas sensor asm design files?

From the Engineer162/CANSAT-M2-2026 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gas sensor asm design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Engineer162 chose for the repository.

Can I test firmware for the Gas sensor asm without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
