arduino 5v Customers Reviews

  • Good for Proto and maybe production

    posted by TimTheEngineer

    - Includes screw through mouts for mounting to a chassis or project board- Very cheap to include two relays, PCB, headers, and driver circuits.- Very simply wiring because of screw terminals- Does come in a small anti-static bag
    If you can run a meter and need a simple 2CH relay circuit you would be hard pressed to build this for less not to mention the time it would take.For a Proto it's a no brainer, buy two.
  • Great product

    Great product, works great, very cheap and saves a lot of development time, excellent quality.highly recommended product.
    I am surprised by the quality of the board
    Excellent board, very easy to use, highly recommended for the price, saves a lot of development time. Very cheap compared to the prices in my country (Argentina). A pretty reasonable delivery period
  • Great for Raspberry Pi and Arduino

    This relay module has an on-board transistor, making it suitable for use with a Raspberry Pi as well as the advertised Arduino. Input current draw at 3.3v is less than 1mA.For RPi use, supply VCC pin with 5v and the input pin will operate happily at 3.3v.
    Be careful, working with mains electricity is very dangerous. Can happily be used at 240v AC by competent person, I'm using them for HVAC control run by the RPi.
    Good product, better than most because of the integrated transistor.
  • Works great with Arduino Uno

    Works out of the box with 5V microcontroller boards like the Arduino Uno. Just hook it up to Ground, 5V and a pin of your choice. Use writeDigital(HIGH) or LOW to switch the relay on or off (or rather close the circuit Common - Normally Open).
    I have only used this relay with 12V DC fans that together draw less than 1A current. Even if the relay is rated higher I would not take the risk to go anywhere near the rating.
    Good value for money if you only need a single relay. Works great with 5V boards like Arduino Uno.
  • Arduino compatibility

    Bright RGB LEDsSimple hookupUser can control two pairs of LEDsFor Arduino use ShiftPWM library
    I was able to make this module work with Arduino using the ShiftPWM library from Elco Jacobs at http://www.elcojacobs.com/using-shiftpwm-to-control-rgb-leds-with-arduino/ . I only had one but I assume that the library will support daisy-chained modules. You will also need a robust 5v power supply, since the Arduino digital outputs don't have the required current to drive the module.
    If you don't mind experimenting a little, I think that this module is good value for the money.
