More Details please refer to this website: www.raspberrypiwiki.com/index.php/DC_5V-24V_Wireless_Switch_Sonoff_SV 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 Soldering Instructions below. Sonoff SV has GIPO reserved to support secondary development. 1 x Remote wifi switch module Support 5~24V power supply. The maximum current: 10A. 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 and repeat timing tasks. Reserve GIPO to support secondary development. 802.11 b / g / n Built-in Tensilica L106 ultra-low power consumption 32-bit micro-MCU, dominant frequency support 80 MHz and 160 MHz, support RTOS Built-in TCP / IP protocol stack Built-in TR switch, balun, LNA, power amplifier and matching network Built-in PLL, voltage regulator and power supply management components, 802.11b mode +20 dBm output power A-MPDU&amp;A-MSDU aggregation and 0.4s guard interval WiFi @ 2.4 GHz, supports WPA / WPA2 safe mode Support cloud OTA upgration Support STA / AP / STA + AP mode UART, I2C, PWM, GPIO Deep sleep maintain current is 10 uA, shutdown current is less than 5 uA Wake-up, connect and transfer data packets in 2 ms Standby power consumption is less than 1.0 mW (DTIM3) Operating temperature range: -40  125
