Making Electronics
Control Unit in SMD
I share free Eagle project, so you can make it as do-it-yourself version. PCB board was designed for YPC SF1601-IP Solenoid's dimensions, but it is compatible with many other 12V solenoids. It's also LiPo 11.1V ready.
PCB dimensions are: 12x46mm. Is' designed for [0805] or [0603] SMD resistors.
