#46441 Hi
I am new to the ESPxxx world and have noted that there are now a large number of model versions with differing capabilities and differing programming methods and no doubt AT comands
Is there a single place where the model differences and the AT commands available for each module is documented?

#46481 All modules are sharing the same chip, ESP8266 from Espressif.
AT Firmware comes from Espressif too, therefore you can rely on the following link for their latest version, whichever the kind of modules that you have :

You can browse on the same site to download their latest firmware.
