SunFounder Single Board Computers Editorial Review
The SunFounder 2 Channel DC 5V Relay Module with Optocoupler Low Level Trigger Expansion Board is a mechanical relay device which can be hooked up to an Arduino R3, MEGA 2560 1280, DSP, ARM, PIC, AVR, STM32 and Raspberry Pi. The FAQ section provides insight into some of the common queries from users. Users have reported that the LED turns on when the printed "open" position is active which could be seen as odd. The package does not include any manual/instructions, however, there are many tutorials available online, and the device comes with opto isolators for both relays. Some users do find them confusing, but overall the product is regarded as great and works as intended. One user hooked it up to their Raspberry Pi and wrote a little Python program, allowing it to trigger wolf sounds and a lightening strike. Another user used this module to switch a 12V sprinkler valve on and off. It is important to note that some users have reported hearing significant click sounds from the switches, which could be too loud for some applications.
