Review on Keyestudio 5V DCAC 4-Channel Relay Hat Shield Module Expansion Board for Raspberry Pi 4, A+, B+, Pi 2 Model B, Pi 3 Model B by David Baer

Revainrating 4 out of 5

Great simplicity for those who only need relays

This board is really good if all you need for a raspberry is a relay because it blocks all pins in the GPIO header. Of course, not all pins are used. So if you want to use other pins, you have to solder the wires to the board, which defeats the simplicity.

Pros
  • A dream come true
Cons
  • Minor problems
