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 make some welding to realize this function. Sonoff SV has GIPO reserved to support secondary development. This version does not have 433 RF function.
Features
-Support 5~24V power supply voltage -Support automatic connect to server, register and update status info. -Support tracking device status and timely remote control through APP. -Support setting single and repeat timing tasks -Reserve GIPO to support secondary development

Soldering Instructions
This is a development board, so you need to do some soldering to realize different functions.
1.As you can see from the figure, R17, R22 default position support common power supply for input and WiFi.
2.When input voltage range is within 7-24V, jumper is auto-disconnect; when input voltage is within 4-7V, you need to connect jumper manually.
3.When power supply for input and controlled device are not the same, please remove R22, R17.
