Sonoff Electronic Brick - 5V Relay

• What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.

Electronic brick of relay can be connected to digital I/O port, when the input of S port is low level, relay will be under ‘disconnect’state; when the input of S port is high level, relay will be under ‘connect’state. It can be connected in series to the LED lights, buzzer or even the loop of a small lamp so as to control the state of the switch.
