SunFounder 4-Channel DC5V Relay Module with Optocoupler High Level Trigger Expansion Board for Arduino and Raspberry Pi DSP AVR PIC ARM
DESCRIPTION
Introduction
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. A relay can be used to control high voltages with a low voltage by connecting it to an MCU. 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.
