Wiring
3.1.
12V Power Supply
As Flarm Speaker consumes around 3W at 12V (when speaker active), there might be
difficulties with power supply especially when using 3.3V power supply.
For that purpose LXNAV has developed an adapter cable (FV12_PWR) which takes external
12V and enables it when there is 3.3V power from source device.
