2 Channels 5V Relay Module

This is a 5V 2-channel relay module that can be directly controlled by various microcontrollers like Arduino, AVR, PIC, ARM, and MSP430. It comes with 2 mechanical relays. Each relay has 'NC' (Normally Connected to COM) and 'NO' (Normally Open to COM) ports. The module also features 2 LEDs to indicate the relay status. Key features include having mechanical relays with status indicator LEDs and both 'NC' and 'NO' ports for each relay. For more product details, visit our wiki page. Your help in improving the documents by correcting errors, adding demo codes, or tutorials is highly appreciated.

To use this 5V dual - channel relay module, first connect it to a compatible microcontroller like Arduino. The module can be directly controlled by these microcontrollers. Each relay has 'NC' and 'NO' ports. Connect your devices according to whether you need a normally - connected or normally - open connection. The LEDs on the module will show you the status of each relay. When using, make sure the power supply is stable at 5V. Avoid overloading the relays. For maintenance, keep the module clean and dry.
