seeed studio Internal Components Editorial Review
The seeedstudio Relay Shield v3.0 is a DIY maker open source board designed for use with Arduino Uno R3. It is compact, easy to install and configure. It works as advertised and is priced reasonably. However, it has a limitation of drawing more amps than what the Uno board can provide when all four relays are active, causing a drop in voltage and the board to shut off and restart. This makes it suitable for use with less than four relays. Overall, it is a good quality product and performs well.
