Questions
How big is the SolarSense v1 PCB?
It measures 77.2 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SolarSense v1 use?
40 parts, built around the LORA-E5-HF, HT7833, TP4056 and KF141R-2.54-2P. 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 SolarSense v1 KiCad files?
From the CaioTeraoka/SolarSense_v1 repository on GitHub, at the commit this page was made from: the board is SolarSense_v1.kicad_pcb and its schematic SolarSense_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SolarSense v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask CaioTeraoka before reusing the design.
