Get in Touch Yabby GPS

Tiny Battery Powered Tracker


The Yabby GPS provides all of the features of the popular Oyster and Remora in a tiny form-factor. The small size is perfect for mounting to small assets or in a concealed location. Available in 2G or 4G Cat-M1/Nb-IoT.

The 4G Modem allows for very-low power operation, and a compact size. Even with the small AAA batteries, up to 3 years' battery life is achievable!

Just Some of the Reasons the Yabby GPS is such a powerful Device..

Tiny Form Factor

The Yabby measures just 85 x 63 x 24 mm! Enclosed in the housing is the GPS and Cellular antennas plus the 3 x AAA battery holder.

The tiny size means it can be attached to any number of assets such as:

Pallets, beer kegs, bikes, animals, livestock and parcels.

Conceal it in trailer lights, hide it in bags, the possiblities are endless!

4G Cat-M1/NB-IoT Modem

The Yabby's 4G modem is compatible with both Cat-M1 and Nb-IoT networks - enabling great new benefits. Traditional cellular network specifications (like 4G LTE Cat 9/12) are designed to provide high speeds and bandwith - to enable smartphone users to stream videos and facilitate other data-intensive activities.
IoT devices don't need this type of bandwidth and are typically trying to solve other problems. These IoT devices require
  • Small data messages typically at low data rates
  • Long Range
  • Low power to allow for long battery life
  • Low cost - to facilitate the deployment of many millions of them
The LTE Cat-M1 and NB1 specifications allow the cellular modem (uBlox SARA R4) to be simpler and smaller, and in turn the Yabby. In our testing we have measured that our new Cat-M1 devices use anywhere from 1/2 to 1/3 of the power of our 3G devices to perform a data upload. This allows the Yabby to still have excellent battery life (up to 3 years) on just 3 AAA batteries!


The Yabby uses bank-level AES-256 device authentication and data encryption to ensure that your data is kept private and secure.
  • Hardware Features

    Low-profile IP67 rugged housing

    The housing screws together for easy assembly, and has 2 convenient mounting tabs. It is low-profile and light making it suitable for mounting on a collar, or placing in packages.

    Dimensions: 85 mm x 63 mm x 24 mm (including mounting tabs)
    Weight: 160 grams with batteries


    AAA size:
    The Yabby uses 3 x “AAA” size 1.5V alkaline or lithium batteries

    Off-the-shelf 1.5V Lithium:
    The Yabby should be fitted with off-the-shelf 1.5V Lithium batteries for operation in cold temperature conditions, or to offer the maximum battery life. These are readily available from retail outlets, for example Energizer Ultimate Lithium.

    Operating Temperature

    -20°C to +60°C

    For operation in extreme temperatures, the Yabby must be fitted with Lithium batteries. Batteries are affected by temperature extremes and typical performance is dependent on temperature.

    High sensitivity GPS

    • Supports concurrent GPS and GLONASS and other GNSS systems
    • 72 channel high sensitivity receiver
    • -167dBm industry leading tracking performance
    • Optimal hot-start performance.


    The Yabby uses both the GPS and GLONASS positioning systems simultaneously. This allows the device to use twice the number of satellites to get a position fix – making it faster and more accurate.

    Low Noise GPS Amplifier (LNA)

    GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Yabby to operate where normal units will fail to receive GPS signal – like in a container stack!

    Internal Antenna

    Internal GPS and Cellular antennas tuned by top RF laboratories to ensure optimal performance.

    3 Axis Accelerometer

    The 3-axis accelerometer allows the Yabby to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.

    Internal Memory

    Sufficient memory to store over 25,000 records. Normally data is sent to the server immediately but if the device is out of range there is space to ensure no data is lost.

    2G or 4G M1/NB1

    The device is supplied with either a 2G or 4G Cat-M1/Nb-IoT modem for operation on various global networks.

    2G Modem
    2G: SARA-G350-02S-01
    850/900/1800/1900 MHz

    4G Modem
    uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands. These new low-power networks are specifically designed for IoT applications, providing great battery life.

    Supported LTE bands:
    1*, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26*, 28 (*roaming bands)
  • Firmware Smarts

    Adaptive Tracking

    The Yabby can intelligently use the accelerometer to adapt the rate at which it gets a Wi-Fi fix and sends it on the network. For the longest battery life the Yabby can be set to do periodic updates, for example once per day.

    OTA Configuration

    The Yabby can be remotely configured and updated OTA (over the air). Device management is performed from Digital Matter’s OEM Server device management platform.

    Recovery Mode

    The Yabby can be remotely switched into Recovery Mode, which switches the device to live tracking and reporting - so that you can get your asset back!

    G-Force Events

    The 3D accelerometer enables High-G event detection, like assets being dropped or involved in accidents, and reports these to the server.

    AES-256 Security

    The Yabby uses bank-level AES-256 data authentication and data encryption to ensure that your data is kept private and secure.

    Man-Down Alerts

    The Yabby can be configured to send an alert to the server when the device has not moved for a set amount of time. Handy for livestock, shipments etc.

    After Hours

    The device can be set to alert on after-hours activity, and to use alternate logging parameters.


    The Yabby has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server and updated Over-the-Air. A future firmware version will enable alerts to be sent to the server upon entering or leaving a geo-fence, and alternate logging parameters to be used when inside a geofence.

  • Device Management – OEM Server

    All Digital Matter devices are fully managed Over-The-Air (OTA) via our OEM Server web interface. The OEM Server seamlessly manages:

    • Device firmware – firmware updates can be done remotely
    • Network (administrator) parameters relating to critical communications
    • System parameters, including GPS parameters, IO configuration, logging options and general device behaviour settings
    • Remote debugging of devices, including being able to trace data, view detailed debug message logs, and view a live trace of the server debug messages
    • Remote disconnect and reboot of devices
    • Driver list downloads to devices – this allows for the Driver Identification on the device to check if the RFID tag / username / PIN is valid, and for specific drivers to be allowed to drive / operate particular vehicles, for example based on licences or permits.
    • Geo-fence syncing with the devices – this allows the device to do advanced in-cab alerting and monitoring such as geo-fence arrival and departure, speed limit alerting, dangerous intersection warnings, turn on warning lights inside a geo-fence, and disable communications inside intrinsically safe zones such as gas plants.
    • Provides a command and message queueing platform to the devices and is incorporated into the remote management and debugging applications

    Data Connectors

    The OEM Server provides Data Connectors that forward data records on to the software platform of your choice, including Digital Matter’s own Telematics Guru platform.
