KEYESTUDIO Single Board Computers Editorial Review

The Keyestudio 5V DCAC 4-Channel Relay Shield Module Expansion Board for Raspberry Pi 4/A+/B+/Pi 2 Model B/Pi 3 Model B is a popular product in the market. The product comes with some flaws, including the stand-offs being too short, mounted screws being too close to the terminals, and the documentation being hard to find. However, it works fine without any external power supply, and it is ok to work with a raspberry pi zero W. It operates on GPIO pins, so just use a pin library and supply power. The product has mostly positive feedback from users, with some needing to be a programmer to get it to work on a Pi system.
