BME688-ML-V1: common questions

What microcontroller does the BME688-ML-V1 use?

The BME688-ML-V1 is built around the STM32L431KBU6TR, from the STM32 family.

How big is the BME688-ML-V1 PCB?

The BME688-ML-V1 measures 25.4 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BME688-ML-V1?

25 components, from 9 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 BME688-ML-V1 design files?

From the Strooom/BME688-ML-V1-PCB 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 BME688-ML-V1 design in my own project?

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

Can I test firmware for the BME688-ML-V1 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.
