1X Wifi/BT Quad Relay Board for IOT Free Basic Source code Safety Warnings

If you are considering buying this item, you probably already know all this but in the interest of your safety, we feel compelled to state all this clearly. So take a few minutes to read it carefully before buying.

AC mains are very dangerous -- Even a 50 V AC supply is more than enough to kill you. Please Switch off the mains before making or changing connections, be very very careful. If you are not sure of anything related to the AC supply lines, please call an electrician to ask him to help you out with it. Do not attempt to interface to mains unless you have adequate training and access to appropriate safety equipment. Never work on high voltages when you are alone by yourself. Always ensure that you have a friend/partner who can see and hear you and who knows how to quickly turn off power in case of an accident. Use a 1A Fuse in series with the input to the board as a safety measure. Basic Wiring diagram is available on our instructables page and github. Please go through it

Fire Hazard: Making wrong connections, drawing more than rated power, contact with water or other conducting material, and other types of misuse/overuse/malfunction can all cause overheating and risk starting a fire. Test your circuit and the environment in which it is deployed thoroughly before leaving it switched on and unsupervised. Always follow all fire safety precautions.

I need help

Good day.
I already received the product, I am very happy with the purchase. I'm going to need another 5 more units.
But first I need to know which pins control the relays.
I dedicate myself to installing climates and I intend to control them by cell phone application.
I can not make the next purchase until I test the operation of this.
If you can send me information please!

Great service, great board with an external box.

Very happy with the purchase. The board worked with an USB cable plugged in. Haven't tried the sample software they provide, instead I flushed the board with my custom firmware and everything worked as expected. They do provide a git hub repository with a software as well as some documentation, which I was expecting to find that on their website but couldn't access product description. Sent a quick email on a weekend and got a prompt answer (very impressed). Headers pin-out on the board are documented and you can easily work out from headers where are things connected, although wished they provide a full circuit diagram.
