what was the question?
An Esp-2 is the same family as Esp8266. If you peel the can off the Esp-2 chip, you’ll see a teeny Esp8266 inside. All the Esp family (Esp1, Esp2, Esp7, Esp12, Esp32 are all based on the Esp8266 chip.
As far as I know.
The different Esp chips are just different GPIO configurations available for the Esp8266, and perhaps integrated bluetooth radios.
I get my kicks with the Esp12-e because it has 4 usable GPIO pins, an analog-in pin, and an SPI bus.
Plus- if the chips gets any smaller (Esp32!), I wouldn’t be able to see and solder it.
The last I heard, the ESP family was not yet supported, so…
I’ll help where I can.
I’m still trying to make my MCP3208 (A/D converter) work with my Esp12-e and Cayenne.
