Questions
How big is the Kb42nerella2 alarm PCB?
It measures 129 × 101 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kb42nerella2 alarm use?
38 parts, built around the ESP32-S3-WROOM-1-N8 and L298HN. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Kb42nerella2 alarm KiCad files?
From the nerella2/ECE445Journal repository on GitHub, at the commit this page was made from: the board is PCB/kb42nerella2_alarm.kicad_pcb and its schematic PCB/kb42nerella2_alarm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kb42nerella2 alarm design in my own project?
Its repository states no licence, so its author keeps all rights: ask nerella2 before reusing the design.
