ESP8266 Community Forum

- Tue Aug 11, 2015 1:55 am #25629 Thank you all so much. As somewhat new in that kind of electronics, having now list of all different (code)names of different possible chips is super useful! From here, if i want, i can search for alternatives too, but now i have at least one example for each purpose, i can think of.

Thank you once again.

If you want to use the features already in the esp8266, which is a microcontroller in itself, I'd refer you to my universal I/O bridge, where you can assign pins to functions (where applicable, the ADC is only on one pin available).

based on the 8574. gives you tons of GPIO, an analogue , and even a variable pot to play with.

Supposed to be for an LCD module, but doesn't matter - basically just a good cheap port extender.
