Questions
How big is the Smart plants breakout ws board rev1 PCB?
It measures 48.3 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart plants breakout ws board rev1 use?
27 parts, built around the IRLZ14PBF. 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 Smart plants breakout ws board rev1 KiCad files?
From the spark-hpi/spox repository on GitHub, at the commit this page was made from: the board is smart_plants_pcb/smart_plants_breakout_ws-board_rev1.kicad_pcb and its schematic smart_plants_pcb/smart_plants_breakout_ws-board_rev1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart plants breakout ws board rev1 design in my own project?
Its repository publishes it under the EUPL-1.2 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
