Trax10153-LoRaWAN GPS Tracker
Trax10153 is a Long Range / low power consumption LoRaWAN GPS tracker. Tracker gets user’s location info via GPS and sends it to IoT server via LoRaWAN wireless network. Compare to traditional GPS trackers (base on GPRS or Cellular network), TRAX10153 uses much lower power consumption hence can last for longer time. It doesn’t need cellular service; system integrators can build their tracking network base on LoRaWAN technology or Join the device to existing LoRaWAN network.
Description
GPS tracker includes a low power GPS module and a 9-axis accelerometer for motion detection. The power for both of the GPS module can be controlled by MCU to achieve the best energy profile for different applications.

Applications
- Logistics and Supply Chain Management
- Smart Cities
- Smart Factory
Option 1 is powered by 1000mA rechargeable Li-on battery and charge circuit, which target for real time tracking with short tracking uplink.
Option 2 disable the charge circuit to get the lowest power consumption and power directly by 2 x 1.5v AA battery. This is designed for asset tracking where only need to uplink a few times every day.
