I am very sorry that it took me so long to upload the photos but here they do not let us leave the house because of the Covid-19, but even so I have assembled the pieces on a breadboard just so you can get an idea of how it looks and how It’s done.
I am still waiting for the PCBs but I do not think they will arrive very soon because the flights from China have been delayed, but with the photos you can see how it is.The device has two relay outputs and a temperature sensor , It has a size of 56mm x 56mm. Right now we have almost 2 and a half months since when we are testing them and we have not had connectivity problems against the Mozilla platform in any way.
I leave you attached the photos. Anything you want to know I am available to all of you.
Thank you and have a nice day.
