Does anyone know which pin on the DW-A8 (DOOAO) module is the ADC in? Diagram shows v1.02 module and no ADC pin but 2 NC pins. The v1.03 unit (which I have) is supposed to have an ADC input.

Can someone update it with information on the ESP-13 module? I haven’t seen any good details on the specifications.

Hello, Gareth. I am waiting patiently to take delivery of some of those NodeMCU ESP-12 chips from Banggood. I just ordered them yesterday so I don’t mean to imply they are slow. To the contrary, I had good service from them the single previous time I bought anything from them. Would it be possible to augment your table with information on the size of the onboard memory? I think (hope?) that the ESP-12 modules contain 4 megabytes or 32 megabits of flash memory, and 96 kilobytes of RAM. Perhaps that is not a fair request, as the flash memory is external to the ESP8266 chip, and the fabricator could have put as much or as little flash memory as they chose to, and it is “hidden” under the metal cover so not apparent to to visual inspection. I know it will be prudent to keep my programs small, but I like to have lots of “elbow room” just in case the program gets a bit large. ;^)

Hello!
Is there the ESP-02 in only three variants?

It’s a bit of a pity that neither this page nor http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family nor https://en.wikipedia.org/wiki/ESP8266 list the memory size for the various models.

Is it correct that all pre-ESP-12 models except the ESP-09 have 512K of memory?

Does anyone know if the 4 pads in the center of the ESP-09 are GND? I am trying to develop a PCB and want to know if they should be left floating or tied to GND.
Thanks in advance.

I am looking for an accurate pinout of the ESP-06. Everything I’ve found shows pads on a board layout, however since these modules have cans obscuring the chips I can’t tell the orientation, and even whether the pictures are looking down on the can, or looking at the bottom of the module. Does anyone know how to figure out the connections on this one?

[…] There are a few different ESP modules; each feature the same chip from Espressif, but they have different form factors and numbers of pins available. This blog post is a good summary. […]
