SIM Size & Access Internal Micro 3FF SIM




Module Nordic nRF9160 internal GPS
Constellation GPS
Tracking Sensitivity -155dBM
*Location Accuracy ~3m CEP, 50%, GPS, Open sky
GNSS Assistance GPS predicted ephemeris data for greater sensitivity and position accuracy
Low Noise Amplifier GPS signals are boosted by a low-noise amplifier (LNA) allowing operation in low signal
Cell Tower Location Optional cell tower positioning (planned)



Rechargeable Battery 3500mAh LiPo rechargeable battery
Input Voltage 6-28V DC (max)
For continuous operation at high temperatures and high output load currents we recommend an input voltage of 12V or higher.
Self-Resetting Fuse Built-in self-resetting fuse makes installation simple and safe
Solar Power Designed to optionally use an external 12V solar panel, 5W or higher
Maximum Power Requirement 4W excluding external sensor power draw



Dimensions 183 x 119 x 39 mm (7.20 x 4.68 x 1.54″)
Weight TBD
Housing Non-branded housing for optional white-labeling
IP/IK Rating Ultra-rugged and waterproof IP68 and IK08-rated housing ensures the Hawk can withstand impact, fine dust, and brief submersion
Installation Multiple installation options for securing the device with screws, bolts, cable ties, rivets, and more. Includes 2 cable glands to allow for waterproof cable entry to the housing.
Operating Temperature -20°C to +60°C (connected to external power)
At < -10°C and > +45°C the internal backup battery will not be charged as a safety precaution due to the dangers associated with charging batteries at extreme temperatures.
Cellular Antenna Internal or External
GPS Antenna Internal
3-Axis Accelerometer 3-Axis Accelerometer to detect tampering (planned)
Diagnostic LED 2 Diagnostic LEDs and Push Button for testing and operational status
Flash Memory Store months of records if device is out of cellular coverage
On-Board Temperature The device reports internal temperature and prevents the internal battery from charging in extreme temperatures.
Internal temperature provides an indication of ambient temperature but may not always be precise.



Digital Inputs 1 x Digital Input with configurable pull up/pull down
0-40V DC input range
On/Off thresholds: On >2V, Off <1V
Can be used for pulse counting (max 40Hz)
Plugin Board The versatile and flexible Hawk architecture caters for plug-in cards that define the 9 inputs/outputs, offering limitless options for interfacing to sensors. See the current card list below or contact us to discuss your requirements.



Auto-APN Auto-APN allows the device to analyze the SIM card and select the correct APN details from a list that is pre-loaded in the device’s firmware
Battery Life and Voltage Monitoring LiPo battery and external voltage readings for “Battery Low” and “Power Loss” alerts
Task Management Powerful task management allows you to schedule tasks or run tasks based on sensor thresholds and events



Flexible Configuration Configure sensor and position update rates
Device Management Platform Manage, monitor, configure, debug, update, and restart devices remotely from our cloud-based device management system
Configuration App Configurable with DM-Link provisioning tool



Third-Party Integration TCP Direct or HTTPS Webhook



Data Security Military-level AES-256 Encryption from device to Device Management Platform to protect the integrity and confidentiality of telematics data. Data forwarded to third-party systems is sent via HTTPS for end-to-end security.



Manufacturer’s Warranty Two-year manufacturer’s warranty. Exclusions apply.
