Bought three of these a little while ago and finally got them running. Have not figured out the Lua thing yet so just using them as generic ESP8266 boards. Using Arduino IDE and downloaded board manager for the ESP8266 chip I have been able run many of the demo programs, including the wifi demos. Successfully made a little http server that lets you toggle one of the LED from a webpage served by the ESP8266. Have not found the perfect “Board” to use under the Arduino IDE but NodeMCU 1.0 seems to work. Now cross checking I/O and LED definitions looking for the best match to the boards hardware features. LED’s are I/O 2 and 16, onboard switch is I/O 0
