I have a small IoT project where I want a network enabled electrical relay. I do not need full network plug nor linux on it. It just should be small and cheap. I feel smart enough to write a small http server in C/C++ (if required) to change the state of the relay. I searched of cause the web and found the almost matching dublicate Cheap IoT microcontroller with PoE
However this is much bigger then what I have in mind. I want a small board with 6 skews to mount the wires (2 or more replays would be fine too). I want to control a device for with less then 25V (I'm not sure but very likely 12V DC). However I do not want to write the TCP/IP stack by my own.
