Questions
How big is the TankGauge PCB?
It measures 53.5 × 51.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TankGauge use?
33 parts, built around the TLV62569DBV, TMP100NA and PMEG6020AELRX. 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 TankGauge KiCad files?
From the jaycedowell/RainCache repository on GitHub, at the commit this page was made from: the board is TankGauge/TankGauge.kicad_pcb and its schematic TankGauge/TankGauge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TankGauge design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaycedowell before reusing the design.
