ESP8266 serial WIFI wireless module
From Federal Burro of Information
picked up 3 3.3 v versions of these. It's been fun trying to get them to work.
1. the 3.3v fdti seems to be 5v
2. the firmware seems bust:
<Crazy garbage characters> Ai-Thinker Technology Co. Ltd. invalid
then I enter:
AT+RST
and get
ERROR
going to try and find an updated firwmare and flash it.
