I hope i'm in the right section of the forum. I've been googling for days and haven't found an answer to help me use this board I bought.
I've been playing around with arduinos for a few months now, and even connected them to internet using the esp8266-01 following some tutorials without a problem. So I wanted to control a relay and radio transmitter with this NodeMCU board I bought a few days ago to avoid using the arduino plus the esp8266 01 and just one board to do the job. I found some tutorials on how to program codes to the board using the Arduino IDE, but I haven't been able to communicate with the board. All I get is a blue led constantly on, nothing changes no matter what I do, I tried powering with the usb micro cable, direct 5v input to the Vin pin and regulated 3.3v to the respective pins and all I get every time is that one blue LED constantly on.
I use mac and also tried flashing a new firmware using pyserial and esptool but no luck there either.
I've downloaded the recommended driver and boards to use with the arduino ide, but nothing.
Any suggestions before I give up and try buying another one?
This is the board I have:
This is it with the blue LED on. No other LED flashes or anything, never.
Thanks for your time!
