Introduction
The iLocate tracking product is a fully integrated electronic device for providing location and
status information of things by way of cellular radio network connection to the internet. This
iLocate tracking device includes a CAT-M1 cellular radio, GNSS GPS receiver, Bluetooth 5.0
BLE transceiver, three axis accelerometer, indicator lights, external data connection, and an ARM
Cortex M4 host controller.

Hardware
The device is powered by external direct current voltage and an internal back up battery. The
external voltage is also used to charge the internal battery.
The host controller manages all setups and communication with the integrated components as
well as providing user data cable connection for external controls, indicator lights and sensor
input/output.
The cellular radio is a shielded module with internal firmware for managing the CAT-M1
network connection, internet protocol data transfers, accessory features, and communication with
the application host controller. The cellular module transceiver uses and on board impedance
matched ceramic antenna.
The GPS receiver is a shielded module with internal circuitry for receiving satellite positioning
data. An internal controller parses the GNSS receiver data and converts the location information
to industry standard NMEA messages. The host processor collects the required data from the GPS
module and formats the location data to be sent over the cellular network to a server computer.
The accelerometer is a +/-2g, +/-4g, +/-8g, +/-16g, 3 axis sensor. The movement and orientation
data is available in up to 14 bit resolution. Interface with the host controller is by standard two
wire interface.
LED indicators are provide to show status of the operation of the device components. There are 4
green LEDs and 4 red LEDs.
The external connection is provide with a 6 pin connector. This connection is configured to
receive and transmit serial data. Other pins can be configured as input or output as required by
specific application requirements.
