# Features {% hint style="info" %} Here you will get a brief idea on what the device is capable of and the important features {% endhint %} * 4G LTE-CAT1+2G with GNSS capable device designed for asset tracking applications where you can charge the device and use for a certain time * Its a super low power device which is optimized for low power consumption when not in use. * Its primary function is to keep sending GPS location to server as long as movement is present. The movement is detected by a LIS3DH accelerometer. * The device has indicators for Battery level, Cellular network status, GPS location status * Has standard USB-C port as charging input and is also used for flashing firmware * Supports internal and external antenna . Default is internal antenna version as we put it in a enclosure. If external antenna is needed inform before hand, we need to change some jumpers for antenna bias. * Can be used for long life tracking applications as well by connecting larger capacity batteries. * Has onboard boost converter for squeezing more juice out of battery and stable operation. * Open source firmware available on Github for customization. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
