Hi, I want to make something along the lines of the Amazon Dash. A wifi enabled button I can connect to web services. This is my shopping list so far:
SparkFun ESP8266 Thing
https://www.sparkfun.com/products/13231
Coin Cell Battery - 24.5mm (PTH LIR2477)
https://www.sparkfun.com/products/12624
Tactile Button - SMD (12mm)
https://www.sparkfun.com/products/12993
SparkFun FTDI Basic Breakout - 3.3V
https://www.sparkfun.com/products/9873
I’m wondering if the battery is a good choice. Will it charge when I connect USB to the Thing? Button a good choice? Am I missing something?
