Sonoff SV

Sonoff SV(safe voltage) is a low power supply Sonoff ESP8266 based development board 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 soldering to use this function, please refer to the soldering instructions below. Sonoff SV has GPIO reserved to support secondary development. This version does not have 433MHz RF function.

Features
Support 5~24V power supply.
Support fast configure SSID and password through APP.
Support automatic connect to server, register and update status info.
Support tracking device status and timely remote control through APP.
Support setting single/repeat/countdown timing tasks.
Reserve GIPO for secondary development.
