CatAlarm: common questions

What microcontroller does the CatAlarm use?

The CatAlarm is built around the STM32G030K8T6, from the STM32 family.

How big is the CatAlarm PCB?

The CatAlarm measures 90 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CatAlarm?

74 components, from 19 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 CatAlarm design files?

From the joshua-sct/CatAlarm 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 CatAlarm design in my own project?

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

Can I test firmware for the CatAlarm 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.
