Customer reviews about Relay modules

  • W. Gracht5V Relay module 8 channels Works well, with 8 channels there are quite a few options to control devices. The optocouplers keep the signal safely isolated.
  • AnonymousBistabiel relay module 12V Fast service great stuff just missed a connection diagram
  • DennisSparkFun Qwiic Single Relay Handy module for switching via microcontrollers. Easy to connect with the Qwiic system, without soldering. Works fine via I2C and is reliable under high load.
  • Jean Magnee12v module relay The relay works perfectly!!! The connection points (screws) are very useful
  • Don A.24V Relay 10A Great relay + received quickly
  • Anonymous5V Relay module 2 channels Product is exactly as described and works well. Perhaps a small manual could have been included about the inputs (low active) and the jumper for separate power supply.
  • Martin Visser5V Relay module 8 channels Works well, just bent connection pins!
  • Tim GTimer relay module - 12V I had a little trouble setting the correct mode, but once you get the hang of how the buttons work, it's pretty easy to operate.
