I am somewhere between pleasantly shocked and mildly alarmed that the arduino sketch I wrote for the seeed wio link (which is now tracking the temperature in my study) appears to have compiled and uploaded - at least to the extent that it gets serial output - on this "Witty Cloud" esp12f module http://adityatannu.com/blog/post/2016/01/31/ESP8266-Witty-Cloud-Board-Demo.html

It doesn't seem to have come back properly from deep sleep, though. Maybe it doesn't have the RST pin wired the same way
