BerryGPS uses the M10478-A2 from Antenova, which is high quality GPS module which is able to track 22 satellites.

Built in antenna:

BerryGPS comes with an inbuilt antenna.

Super Cap:

The SuperCap keeps the ephemeris data stored in the battery backup RAM for 2 hours. This allows for faster acquisitions when the module is power cycled.

Fix indicator:

The fix LED will flash once a second when a fix has been obtained. The fix signal is also presented on an output pin.

PPS:

BerryGPS also includes Pulse Per Second(PPS) functionality. With a LED which will flash on every pulse and an output pin to be used by a microcontroller for time syncing.

Standby Pin:

Include and pin to place the GPS module into standby mode.

Periodic mode:

Periodic mode is a module controlled mode that reduces current consumption by only waking the module for short periods to maintain fix data.

Connection for external antenna:

BerryGPS also includes a uFL connector for an external antenna, which can be used when BerryGPS doesn't have clear access to the sky.

BerryGPS comes with;

• BerryGPS PCB
• 1 x female header
• 4 x nylon standoffs, nuts and screws

Raspberry Pi not included.

Optional External Antenna

We also have an optional external antenna.

Connecting this antenna to your BerryGPS will improve its GPS reception by 28dB.

An external antenna is useful your BerryGPS doesn’t have clear access to the sky. E.g. when used in doors.

This antenna is waterproof and also has a magnetic base, it is 3 meters in length and uses a SMA connector.

Comes with a uFL to SMA adapter to assist with connecting this antenna to a BerryGPS.

Some very basic soldering is required to solder on the female header. If you would like us to solder the header for you (at no cost), please leave a note when ordering.
