SainSmart Electromechanical Relays Editorial Review
The SainSmart USB 4 Channel Relay Automation(5V) is a computer-controlled switching device with a good interface that works with Raspberry Pi. However, the relays cycle at random times, so it may not be the best choice for applications that require more precise control. The product comes with poor documentation, and it may take some time to figure out how to use it with programming languages such as Python. On the positive side, the device works well with Windows 10 and Ubuntu, and it works efficiently if connected to an additional power supply.
