The traditional relay module has complicated wiring and is not friendly to beginners or students. The simple switch module simplifies the wiring method for connecting traditional relays. The input end is equipped with an adapter, which can be compatible with most power sources, battery boxes, DC power supplies, power bank, etc. While simplifying the wiring mode, the functions of relays NC and NO are retained, and the normally open and normally closed modes can be switched by simply adjusting the toggle switch.
DFRobot's latest easy relay module uses a standard Gravitysensor interface and supports a wide voltage input of 3.3V-5.5V, making it easy to connect with main control boards such asArduino, control board, and so on. Meet your needs in control applications such as robot control, light control, smart home, security, etc.
