ESP8266 Community Forum

Hello everyone..
My wifi module seems to be broke. I couldn't flash nodemcu firmware.
This is my config flash. I'm using arduino for flashing esp8266-07
Arduino Uno ------------><--------------------------Esp8266-07
RX----------------------------><--------------------------------------TX
TX----------------------------><--------------------------------------RX
GND--------------------------><-----------------------------------GPIO0
GND--------------------------><----------------------------------GPIO15
GND--------------------------><------------------------------------GND
3v-----------------------------><------------------------------------VCC
3v-----------------------------><------------------------------------EN
3v-----------------------------><------------------------------------GPIO2

When i flash the esp8266 with nodemcu, It stuck on : Note:Begin find ESP8266.
And the red led on wifi module dim a little bit and blinking.
Can i 'save' the wifi module? i think buying a new one is not the best option here
Need help everyone..
Thankyou for your kind answers

Anyone?
please..

most probably your module is not broken but your method to flash it.
Just buy a decent USB/serial converter (preferably with CP2102) and problem will be solved

Thanks for reply shufti..
After some try and error. I finally figured it out.
So the config flash should be like this (if you're using arduino for flashing nodemcu firmware)

Arduino Uno ------------><--------------------------Esp8266-07
RX----------------------------><--------------------------------------RX
TX----------------------------><--------------------------------------TX
GND--------------------------><-----------------------------------GPIO0
GND--------------------------><----------------------------------GPIO15
GND--------------------------><------------------------------------GND
3v-----------------------------><------------------------------------VCC
3v-----------------------------><------------------------------------EN
3v-----------------------------><------------------------------------GPIO2

If it fails too, check your wiring config. It may be wrong or not connected yet.
Anyway thanks for reply.
Cheers
