6 HARDWARE
6.1 MAIN PROCESSING COMPONENTS
The GAT comprises 2 primary communication and processing modules, the Quectel BG96G, and the Silicon Labs BlueGecko
EFR32BG12. The BG96 and EFR32BG12 operate cooperatively and communicate via a dedicated UART serial interface, using a
proprietary, message packet-based protocol (Ref. 7, GAT Software Radio to Sensor Message Protocol).
6.1.1 BG96
The BG96 hosts the radio/modem and is primarily responsible for cellular communications to ThingSpace and for GNSS/GPS
positioning.
6.1.2 EFR32BG12 (SENSOR PROCESSOR)
The EFR32BG12 is primarily responsible for collecting periodic sensor measurements and for generating events or alarms
based on those measurements. It hosts a Bluetooth Low Energy (BLE) radio for use with applications such as reading data
such as temperature from a BLE sensor.
6.2 SENSORS
GAT has the following peripheral devices that interface to the EFR32BG12 to support system operation and to support taking
sensor measurements:
• Bosch BMI160 3-Axis IMU/Gyroscope, with up to 16g of motion/force detection, and 0 to 359 degree orientation around 2
independent axes and tilt-angle recognition around 3 independent axes
• Bosch BME280 sensor with Temperature (-40 deg C to 80 deg C), Pressure (0 hPa to 1300 hPa), and Humidity (0% to 100%)
• Maxim MAX17260 Battery Fuel Gauge
• Liteon LTR303 ambient light sensor, with 0 to 64K Lux measurement
• Silicon Labs / Expressif ESP8286 WIFI (for LAAS)
• 1-wire bridge to support a thermistor device
