So this question might sound a bit weird since I'm pretty new to programing development boards. What I need is a board that can be powered using a battery and that also supports Bluetooth. I'm interested in the Arduino Blend Micro(https://store.arduino.cc/blend-micro), how do I know if this boards supports the usage of batteries?
It would be even greater if the board would charge its battery when connected to a power source via USB. However I have no idea what this concept is called, nor do I know how to search for a board online that supports this feature.
