Antenna characteristics for Swarm ½ wave Antenna.
A GPS antenna is
required for operation
. Any passive GPS antenna with an appropriate
connection to the Tile’s U.FL male connector or via the GPS_OUT pin is acceptable for use.
One such example of a passive antenna is:
.
Active GPS antennas are supported at 3.3V and up to 35mA. Any active antennas that require a
different voltage or maximum current must be powered by the user’s host device.
