 +  * The Webduino Smart is extremely similar to the "[[https://vimalb.github.io/IoT-ESP8266-Starter/Witty/info.html|(Gizwits) Witty Cloud]]" board, one is probably a clone of the other (same pin number for on-board components). The Witty Cloud board includes an FTDI daughter board which simplifies development, this daughter board may even be compatible with the Webduino Smart.
