Window Sensor: common questions

What microcontroller does the Window Sensor use?

The Window Sensor is built around the STM8L051F3P6, from the STM32 family.

How big is the Window Sensor PCB?

The Window Sensor measures 28.9 × 64.5 mm, has 2 copper layers and is 1.09 mm thick.

How many components are on the Window Sensor?

40 components, from 27 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 Window Sensor design files?

From the npeixoto64/ExitGuardian 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 Window Sensor design in my own project?

The repository has no license, so all rights stay with npeixoto64. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Window Sensor 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.
