Questions
How big is the MonitoringSystem PCB PCB?
It measures 89 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MonitoringSystem PCB use?
96 parts, built around the ESP32-S3-WROOM-1-N16R2, TDC1000PW, LM1117MP-3.3 and TDC7200PW. 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 MonitoringSystem PCB KiCad files?
From the Danielbaker31/HouseholdWaterMonitoringSystem repository on GitHub, at the commit this page was made from: the board is MonitoringSystem_PCB/MonitoringSystem_PCB.kicad_pcb and its schematic MonitoringSystem_PCB/MonitoringSystem_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MonitoringSystem PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Danielbaker31 before reusing the design.
