Overview

Sonoff SV (6).JPG

Sonoff SV(safe voltage) is a low power supply Sonoff version,which supports 5-24V power supply. The power separation circuit enables it to control AC or DC power for the connected device, but you need to do some welding to realize this function, please refer to Solder Instructions below. Sonoff SV has GIPO reserved to support secondary development. This version does not have 433MHz RF function.
