Questions
What parts does the MQP Kat Foot Sensors use?
31 parts, built around the BMP280 and MIC5501-3.0YM5-TR. 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 MQP Kat Foot Sensors KiCad files?
From the SmallKatMQP/FootPressureSensors repository on GitHub, at the commit this page was made from: the board is MQP Kat Foot Sensors.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MQP Kat Foot Sensors design in my own project?
Its repository states no licence, so its author keeps all rights: ask SmallKatMQP before reusing the design.
