Currently I'm getting slightly confused with all the different directions and YouTube videos.
My goal is to power the Arduino nano rsp 32. For that I have a Lithium Polymer battery 3.7V/820 Mah and a Zalati Mini Boost Module DC-DC 3.7V to 5-12V.
It seems I have to connect the module to the pins on the Nano but I don't see any holes. Can a breadboard help here?
If you have the nano with pins, then put it into a breadboard and connect to Vin and GND.
If you have the one wirhout pins then you will need to solder wires to Vin and GND
