Can anyone recommend a simple micro-controller with some I/O (<8) that can be powered using PoE, something cheap like Raspberri Pi Zero. The requirements are:
- Support PoE integrated. No power battery maintenance.
- Support TCP/UDP communication
- few I/O.
The thing is that if I need a power adapter per each micro controller distributed around the house I will require a lot of budget. Having a set if chips with PoE I avoid occupying the power outlets and I have safe communication at the same time.
Basically what I want is to through some Ethernet cables and add some sensors and actuator without having to set up a full Arduino in each end-point. And not having to change the battery every year. And also I don't want to spend extra money buying adfruits and shields.
Another alternative that fulfill somehow my requirements, although it is not what I was thinking of, it is to install a commercial Wi-Fi power outlet. I find it bit expensive for the amount of units I need.
Here is one example from Amazon.
- This solves my power requirements by taking the power directly from the power net.
- Provides communication over Wi-Fi.
- I can connect any microcontroller with a power adapter to it.
- Since it is commercial Hardware I believe that it will provide some safety level of operation, in comparison to a testing board I could do on my own, I won't like to set the kitchen on file because a silly short cut.
Of course, the fun will be to develop the application by myself
