Questions
How big is the HydroponicFlowerControl PCB?
It measures 101 × 101 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HydroponicFlowerControl use?
260 parts, built around the SN65HVD230D, ADS1115IDGS, CH224K and ADM3260ARSZ-RL7. 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 HydroponicFlowerControl KiCad files?
From the OpenHydroponic/rootmaster repository on GitHub, at the commit this page was made from: the board is HydroponicFlowerControl.kicad_pcb and its schematic HydroponicFlowerControl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HydroponicFlowerControl design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
