4 Channel Relay Module,5V High and ,Trigger Relay Control

This is a 4-channel HIGH level trigger relay, applicable to Arduino and Raspberry Pi, Relays are suitable for driving high power electronic devices such as lights, electric fans and air conditions, There are two soldering points for 5V and GND at the two ends of the module. So you can just weld other relay modules to it and have a relay module of more channels, signals of which are independent of each other. You can just unplug the headers to disconnect the device with the module after the experiment and don’t need to unscrew the wires in the socket. Kindly reminder: Be careful with your fingers when unplugging the headers.
