-I only worked with Esp01 so I don't know Esp12. Can I program Esp12 from Arduino.(Like I did with Esp01 https://simple-circuit.com/wp-content/uploads/2018/06/arduino-esp-01-program.png )
-Can I convert Esp 12 to ethernet ? (https://github.com/cnlohr/espthernet/blob/gh-pages/hardware/nodemcu-ethernet.png) here I found something.
-I am like beginner level. I am using Esp01 very easy with UART. I need this Esp ethernet thing. Is it possible ?
