  • Excellent four channel control module - Easy to use - Very practical

    posted by EdTronique

    I've used some much more expensive computer controlled modules in the past that were similar to this but this one beats them all for quality to price. Can easily be adapted to most computer interfaces and also easily controlled by an Arduino or Raspberry PI etc. Easy to configure and control with a program or Arduino.
    Great 4 channel domestic voltage control module. Including a one page manual of operation could be a welcome addition - for $.50 cents extra if needed.
    Unbeatable for quality to price.A must have module for gadget users.
  • Relay board for Arduino and Raspberry Pi

    Good quality. The first delivery had one non functioning relay. After 2 weeks I received a new board without any costs: great service Deal Extreme !!
    I'll buy some more of these in the future.

    Standard 4-channel relay board. Has transistors for the relay coils, and flyback diode protection. Relays close on HIGH signal, just as you would expect.
    Board draws 3mA with no relays closed. Each relay coil draws about 80mA when activated. Red "power" indicator, green relay indicators.
    Not sure what more I can say about it? It's a standard 4-channel relay board.
