I am really fresh in to the Arduino game and got my hands on a BLE Nano 2 for a project that I am doing.
Currently, I want to make a test to read out a potentiometer through a analog input and send it over BT to my android phone.
Therefore I was thinking to put the BLE nano 2 on a breadboard and power the breadboard with an old powerbank (for charging a smartphone) that I’ve got. This powerbank has an output of 5V-1000mA.I also have a 2000mA powerbank, but if possible I prefer to use the 1000mA one.
Do you think this is a safe and working set up?
