I guess topic tells most. I want to build a board with
- ESP8266 (preferred Wemos D1)
- T sensor
- LCD (shield?)
- 2 buttons (UP/Down)
- Battery feed or more preferred: feed of mains (so an 220v AC--> 5v (or 3.3.?v) DC step down converter)
- 220V relay (shield ?)
I don't mind soldering a bit but preferably I click a couple of shields into one board. Problem is: what to get. I've been scouring over banggood and aliiexpress and there are a LOT of shields and modules and I don't even know whether the above configuration can be attached to the ESP (most likely it will, IRC 6 pins for LCD, 2 for the buttons, one ADC for sensor).
Bottom line I'm overwhelmed by choices and underteached in compatibility, hence I'm looking for advice.
EDIT: to give this topic a bit of focus, here some components I'm thinking off:
(is there a way to wrap hyperlinks on this arduino forum? I can't find any way)
Dual Base Shield:
Step down convertor
Again, I'm quite clueless whether this is all compatible with eachother and whether these are the best choices.
