Questions
How big is the Sensor driver PCB?
It measures 44.9 × 38.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor driver use?
22 parts, built around the TPS63900DSKR, 2N7002K and BM04B-SRSS-TB(LF)(SN)(P). 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 Sensor driver KiCad files?
From the garthwebb/greenhouse repository on GitHub, at the commit this page was made from: the board is remote-sensors/pcb/sensor-driver/sensor-driver.kicad_pcb and its schematic controller/pcb/Greenhouse Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask garthwebb before reusing the design.
