Use in production environment

 Hello, 
 I would like to know if M5Stack products can be used directly in production environments (civil and industrial) or can be used exclusively for prototyping.If they can be used in a production environment, what are they and where can I find the relevant certifications. Thanks

 Depends on the environmental conditions That was one of the reasons for the change from buttons to touch screen. There have already been a few industry uses now. If there is anything you want to discuss in private I can help as I have almost the whole range. Feel free to private message me.

 @robski Of course, however, this is just a web page that anyone can create and has no value when you have to present certifications for a project.

 Support sent me certifications for K128, K010-AWS, K034. 
 The others are modules without certifications.
 So contact support directly, they are quick to respond and will send you the required certificates.

 @ajb2k3 thank you so much! 
 Since the controllers I'm interested in are certified (K128, K010-AWS, K034) the only question left is what to do with the rest of the products which then become fundamental such as sensors, relays, etc. which are without certifications.

 The thing is that when you create a finished product that you wish to sell, it is your duty to send the finished product out for testing and individual certification. if this is for a private in house deployment then again it will be up to you to get the testing and certification should your in house managers want it.
