Well, I developed an Iot project based on Node-RED and saw that the tool has proved to be the best choice that I could have made. As a result, I really want to carry out my project, developing something definitive.
Until now, I run Node-RED, the broker mosquitto and a VPN client on a PC with win 10. However, I have seen a wide application of Node RED on microcomputers, such as the raspberry pi. I find it interesting to use it as a definitive server to run my software, the energy and mechanical expense is low, in addition to being compact.
I wanted to see your opinion: what is the ideal model, that can run the software without difficulties? how much memory is needed?
And already taking advantage, which operating system would be the best? Ubuntu, raspbian? give me options.
