    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

    Update to my review : Running Windows 10 and I did not need to install any drivers. Plugged into the USB port and everything “just worked”


    The problem with the USB ports is widespread; every module with this kind of micro-USB connector is not designed for frequent plugging. If one uses the programmed module in a device, powered by the power pins, and only uses the USB port to occasionally update the firmware, for example, these modules are the cheapest option to have an ESP8266 with the large 4MB memory and the addition of a 32Mbit external SPI flash.
