The LUA software worked fine out of the "box". I decided to flash one with Basic V3.0, R5. After a few tries using the Nodemcu firmware flasher (BASIC one didn't work) I was able to flash. All seems to work fine with one exception, the serial port (RX/TX) doesn't seem to send any data on print or serialprint. Just wondering if anyone else has tried and could give some advice. Everything else seems to work fine, was able to operate the relays (GPIO12 and 13, also the GPIO16 LED) using:

Very cool board for $6.00!
