One nice feature of the PowerMouse is that it has a built-in bluetooth module, so it can wirelessly transmit flarm and GPS data to a display device (such as Oudie or Android) running your preferred navigation software. It then has two RJ ports that can be used to connect it to a Flarmview or other display.

The Power Mouse is about 1/4 the size of the Powerflarm core unit which can be an advantage when space is at a premium.

The LX Navigation Flarm Eagle is another option and it is even smaller than the PowerMouse, but does not have the bluetooth capabilty.
