Hi!
I intend to pass to MRF24WG0MA/B, but for now I am using nodeMCU.

I tried to lookup the ADC information, but couldn't. Can someone tell me if the nodeMCU ADC with ESP8266 is good enough for transferring audio over Wi-Fi? The frequency is 20Hz-20kHz. I think its a SAR ADC, which should be good for a few MHz. Its a 10bit ADC.

Just a few of the projects done on web.

Thanks, these projects are badly documented. I will accept that it works. I think it can also be used for video.

I will start with building the hardware.

 

The ESP8266 en-total is poorly documented and projects, in general, not
done on an engineering level basis. The docs reflect this.

Open source is rarely a blessing. No one is responsible.......

I have yet to find complete datasheet para-metrics on its ADC to do a
real error budget. For all we know its only good to 2 bits over T and V

Congratulations on the new avatar :d. I finally noticed.

I will test it as much as possible, here is the circuit.

EDIT: The circuit is not complete, there are some mistakes and the FM radio part can be ommited. Instead only using the nodeMCU will do, maybe with an amplifier for the microphone.
