ESP8266 Community Forum

Hi lovely ESP8266 coummunity!

I'm new here and also new in electronics and also new in esp8266. NEW!

I have some questions and hope you can help.

-There are a lot of different versions of the ESP8266: wiki/doku.php?id=esp8266-module-family - don't see any big difference, only that they are from different manufacturer?


I wanted to do this tutorial of the smart button: https://www.hackster.io/iboboc/smartbutton-pro-06ce5d

The linked ESP8266 esp-07 is sold out, so I searched another one:

http://www.banggood.com/ESP8266-ESP-07- ... mds=search

-In the wiki there is mentioned that some of the esp-07 have a bug of wrong GPIO labels, can we see on the pictures of the linked product if it is ok?


-Do I need an extra aerial so that the esp-07 works?

-Is this everything on hardware, that I need to flash the esp-07 for lua?

-When I understand, ESP8266 is only for prototyping, how can I move from that prototype to a commercial product? Is it possible - I mean is it allowed - to sell my end-product with the esp8266 in it?


Thank you very much for your support, I'm really interested to learn more about the esp, I have done one project with Arduino and Bluetooth, I'm a software engineer student.

http://www.esp8266.com/u/espsource list all the modules... look for ESP12E or F they are the best, all I/O is pinned out, and sometimes you can find PCB breakout boards for them, if you need USB connection then pick maybe Geekcreit-Doit-NodeMcu very nice also.

So the ESP12E or F they have the ESP-07 on it? I think for testing its nice, but when I want to do the exact same project as in my link (https://www.hackster.io/iboboc/smartbutton-pro-06ce5d) isn't it better to take the ESP-07 (the same as in that tutorial)?

And is it allowed to use the ESP in a commercial product?

thx a lot!

Esp8266 have Fcc printed on them so they should be legal to use for production (in the US). I have used different esp8266, and my opinion is that it depends on your needs, thats why there are different versions. Some are tiny like esp8266 11, some have few and some have more usable pins and some come on a PCB as mentioned with usb if you need that. So it all depends on your needs.

And no you dont need an aerial for it to work, there is a antenna soldered to the board, unless you want to extend wifi range significantly, but as it is it pretty good.

The usb TTL you mention is good, but I would get a couple of different kinds, I have had issues with drivers before. see: http://hackaday.com/2016/02/01/ftdi-drivers-break-fake-chips-again/

Although with a different usb ttl http://www.banggood.com/USB-to-RS232-TTL-Serial-FTDI-Chipset-FT232-Computer-Converter-Cable-p-80871.html?rmmds=myorder but from the same store Banggood, I didn't know what was wrong with my esp8266, turned out it was the usb ttl (after many sleepless nights). If you are buying it for 3 or 4 dollars it probably is a clone.

I have not used esp8266 07 but from googling I see the pins match up with with the one you are refferin to...

If you are doing the same exact project as mentioned, why dont you use esp8266 07? As the original.
Good luck!
