8 Channels 5V Relay Module

This 5V 8-channel relay module is a versatile device that can be directly controlled by a wide variety of microcontrollers, including Arduino, AVR, PIC, ARM, and MSP430. It comes with 8 mechanical relays, each having both 'NC' (Normally Connected to COM) and 'NO' (Normally Open to COM) ports. The module also features 8 LEDs to clearly show the status of each relay. Visit our wiki page for more details about this product, and your help in improving the documents by correcting errors, adding demo codes, or tutorials is highly appreciated.

Using this 8-channel 5V relay module is easy. First, connect it to your microcontroller, like an Arduino. You can then use the microcontroller to control the relays. When using, remember that the 'NC' port is normally connected to COM and the 'NO' port is normally open to COM. Check the LED indicators to know the status of each relay. For maintenance, keep the module in a dry and clean place. Don't expose it to extreme temperatures or moisture. If you find any issues, refer to our wiki page for troubleshooting.
