So locate the following lines inside the {{fname|setup()}} function of your "mission1-serial-radio-capture.ino" sketch (the emitter code running inside the CanSat).

{{ambox|text=This is an estimate. In real life, the current sink by the project is not constant so energy is not sink out constantly from the LiPo.}}

== Conclusion ==
You should now be able to unplug the Feather from the USB connector then still receive the telemetric data over the air :-)
