How to program this board

Hi,
I bought the picture board of ESP8266, It can’t be recognized by Arduino IDE.
I did:

  1. copy the below code in the Additional boards Manager

http://arduino.esp8266.com/stable/package_esp8266com_index.json

click OK to close the preference Tab.
2. Installed esp8266 from Board Manager.
What else please?
Thanks
Adam

Plug in the USB cable.
While holding down the Flash button briefly press and release the RST button. Release Flash.
The PC should find a new device. Install driver for the USB-Serial chip if needed.

You may look up a guide on how to backup the stock firmware first, just in case you may want it later.

Thanks.
I’ll do it.

Here is one backup/restore guide.
Your board seems to have 4MB flash, but check the description at wherever you bought it from.

Thanks,
I’ll ref. it.
