Great product!
Totally recommend I just don’t have a use for it yet but GPIO works great on it I have the keystudio arduino clones I find them more visually appealing and pleasing. Very high quality.

Documented and easy to use
It is not obvious how to connect this to a Raspberry Pi but it works well with an Arduino Uno and a sample program is available.

arduinoにつなぐだけでOK
AC120V DC24Vと耐圧は少し低めではありますが、arduinoからの電源供給からで動作させることができる 非常に使い勝手のいいリレーモジュールです。動作確認用にLEDも内蔵されているので、動作状況も目視できます。 耐圧さえ範囲内であれば、非常におすすめです

Works as advertised, GREAT Product Support
These function as advertised. They're fixed on pins 4-7 and are not isolated relays. Fits the needs of the application I used them in, overall great! Only bad things I can say about them: Do not pass through the SDA/SCL signals on the R3 boards No jumpers to configure which inputs control which relay, would be nice to have at least one alternate for each, but the rest of the project can be designed around that. The LCD/Button shield sold by KEYESTUDIO does not work with this shield, as it uses the same pins, hence the second issue. If only needing relays to add to a quick project, this is what you need, reliable after a month of pretty frequent use on both motor and LED lighting loads.
