EXTERNAL POWER SUPPLY
 The mini USB socket can be used to power the instrument and simultaneously charge the internal battery.
 An external stabilized 5VDC power supply (e.g. a solar panel, external power bank, etc.) with a minimum of
150mA is necessary to turn the instrument on; any excess power will be used to charge the internal lithium
battery. Proper solar panels are suitable to power the instrument.

Important Notice
: do not keep your Digifly AIR connected to its USB port in flight or in any situation where the
USB cable could create an undesired movement to the charging port, applying force on the soldered connection
of the mini USB, resulting in its detachment from the board. This also applies when you carry your AIR in your
harness or a backpack: do not have the USB cable connected to it.
