  • Very high build quality

    posted by pryur

    Very quality build. All the materials used in device are high quality: relays, board itself and connectors.It has leds, one for indicating power, and four for indicating relay state.Delivery package is also high quality.
    It arrived in a very nice package - corton box.I use it in my smart-home project for remote controlling of outlets, and control room lighting.Can operate as a normally open switch and as normally closed switch.It can fit power under appox 2500 Whatts.
    Recommend to buy, it is worth the money.
  • Works like a charm!

    Very good construction
    For reference, it works perfectly with the standard LiquidCrystalDisplay library from Arduino, but it is necessary to change the constructor call from the standard:#include <LiquidCrystal.h>LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);to the (checked and running):#include <LiquidCrystal.h>LiquidCrystal lcd(8, 9, 4, 5, 6, 7);beside of this, anything I have checked it works.
    Nice value for price. More yhan I expected.
  • Good for prototyping

    posted by mekkuli

    Fits perfectly Arduino UNO (as it should) and helps very much in fast prototyping.
    (cont from cons) ...but actually this helps the prototyping a lot as it has a row of 5V and another row for ground. Saves a lot of hassle with wiring.
    You need several of these when working and testing a new project. You can wire everything and then switch to another test project just by pulling out the expansion board and adding another.
  • 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
  • I love this kit!

    Great value for the price.Don't need anything else, can use the arduino with lcd out of the box.Great community support.The analog pins can be used as extra digital pins.The buttons on the lcd are all connected to 1 analog input by different value resistors.
    Is a great idea for teaching entry level programming and circuit building.
    Definitely a good buy for someone new to micro controllers.
