Thank you Lee, i also tried that rx-tx tx-rx but i cant connect to usb and the code doesnt flash into the esp8266...ide keep saying connecting...

Upload program to the board via connecting the USB first, and then connect DFPlayer - A Mini MP3 Player with the hard serial port, otherwise there may be a communication conflict.

Is the 3w speaker rating at 4ohm or 8ohm impedance?

Our previous tests were conducted with an 8ohm 3w specification. We recommend using this specification for optimal results.

I tried to install this module to esp8266 rx to rx and tx to tx but i got the error message rechcheck your connection and insert sd card??

Think of RX as listening and TX as speaking. If you connect RX to RX (listening to listening), there is no data being exchanged. You need to connect RX to TX and TX to RX (speaking to listening). Hope this helps.
