[GreenKeys] ESP8266 WiFi Module UART

[Jeffrey D Angus]

I just stumbled across this on eBay.
<http://www.ebay.com/itm/141454423509>
With shipping, $5.59.
Here's the data sheet:

More documentation:

And some app notes:
<https://www.zybuluo.com/kfihihc/note/31135>

I notice this one seems to use the I^2C serial data buss. That's not the
same as RS-232 serial data.
It also runs off of 3.3 vdc and will HCF (Halt and Catch Fire) on 5 vdc.
