Hardwired Equivalent of the ESP8266?

[JonSea]

The ESP8266 has made WiFi connected internet cheap and easy. Is there a similar solution where it's desirable to use a hardwired connection? I'm thinking similar applications to where you'd use an ESP8266 module. A wired node where you would turn on one or a few lights, read temperature and humidity, and communicate back to a PC, a RPi, etc.

There was a design in the Silicon Chip Magazine in November 2009 that was based around a DSPIC33FJ64GP802 This was reprinted in the EPE magazine in December 2011 Jaycar in Australia do a kit for it.

So you want a 10 base-T "thing". Years ago before wireless was low cost, there were boards like that.

An internet search shows some industrial versions that cost too much.

If you can do Python or C think about getting a Raspberry Pi 0. $5.00

Hmmm. I like the Pi 0 idea. This gets the cost point to a place that makes sense for a temperature sensor and similar devices.

It's kind of amazing to me with modules like this and even simpler things that the cost for a module is far, far cheaper than I can even buy the components. Building a circuit board around a module or even a collection used to seem kind of a half-assed way of doing things but the economic reality makes sense to build around pieces that are proven and rolling off production lines by the (many) thousands.

An Arduino ethernet shield should make this possible.
