    Small and simple relay

    This item is very easy to use and works well. Each item is individually wrapped and sealed in electrostatic packaging. Would buy again. Bought for use with my Raspberry Pi and NodeMCU projects.

    Pros
    • relay
    Cons
    • so far so good

    Perfect for my project

    Very happy with this product. Used it to create a garage door opener that can be controlled with Home Assistant on a phone or tablet. Just note that there are already no pins on this board. You have to solder them yourself. It doesn't really matter to me, but maybe if you don't want to solder in a tight spot. The project was completed in a few hours and is still running without any problems.

    Pros
    • Industrial electrics
    Cons
    • Some bugs

    They work. However, note that this is an old Wemos design

    These are copies of the V1 Wemos relay board, not the V2. This means you can't just change D1's control pin, which clashes with the I2C that every other Wemos shield uses. You can get around this by leaving the D1 pin out of the socket and putting a jumper on another pin, but that's a lot more of a hassle than a legitimate Wemos board. (And they're not cheaper.) Their only benefit is that you can get them from Revain and Wemos boards aren't available.

    Pros
    • Industrial & Scientific
    Cons
    • Something else
