A few newbie questions here.
I currently have 2 ESP-12E development boards (https://www.amazon.com/Makerfocus-ESP82 ... us+esp8266) - that I'm playing around for 2 different projects.
One project will use the board "to wifi enable" a RF remote so it will basically need to be always on listening for a request (acting as a webserver).
The other will be a sort of IoT button, something that could fit in a glove compartment or even on a keychain and when you press a button it sends an HTTP request.
My question is about powering the board for these examples. I'm assuming for project #1 (the wifi remote) I will be better off plugging in the device to a hardwired power source? How much time could I get from AA batteries?
For the second project I want to keep it as small as possible. Since the device can sleep until the button is pressed could I get away with a coin cell battery? How long might it last assuming the button is only pressed once or twice a day?
Also, what are the major differences between the dev board I listed above and a board like this? https://www.amazon.com/gp/product/B01N7 ... _i=desktop
I can tell the size is different but how beyond the physical connections what other considerations are there between using the two types of boards?
Thanks!
