We exclusively use KiCAD, and open source electronic design software suite, to draw our schematics and layout our PCBs. We also use OSHPark, an domestic PCB batching company that uses US based PCB manufactures, to manufacture our boards.

Si7021 is a simple moisture and temperature sensor IC that communicates though I2C.

We especially thanks IO Rodeo for patiently helping us get started on using KiCAD.
