Questions
How big is the Solar charger devboard PCB?
It measures 50 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solar charger devboard use?
16 parts, built around the TPS3700DDCR and AO3415. 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 Solar charger devboard KiCad files?
From the M-C-machts/PCB-Projects repository on GitHub, at the commit this page was made from: the board is solar-charger/solar-charger-devboard.kicad_pcb and its schematic Weather-Station-Seeed-ESP32C3/Weather-Station-Seeed-ESP32C3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solar charger devboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
