Questions
How big is the Monitor pcb PCB?
It measures 68.7 × 47.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Monitor pcb use?
55 parts, built around the STM32U031C8T6, NAU7802SGI, TPD2E2U06DCKR-TP and DMG2307L-7-F-VB. 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 Monitor pcb KiCad files?
From the GarronAnderson/InsideMyHive-V2 repository on GitHub, at the commit this page was made from: the board is monitor pcb/monitor pcb.kicad_pcb and its schematic in hive sensor pcb/in_hive_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monitor pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask GarronAnderson before reusing the design.
