iWave Telematics Control Unit Supports GPS, 4G LTE, WiFi, and Bluetooth

We’ve often written about iWave Systems’ single board computers, development kits, and systems-on-module, but the company has also been offering automotive products such as a Linux based OBD-II Dongle.

And they’ve just introduced a new one called Telematics Control Unit (TCU) based on an Arm Cortex-A7 processor and offering GPS, 4G LTE Cat 4/1/M1, WiFi 5, and Bluetooth 5.0 connectivity for vehicle fleet management and insurance companies that want to know how drivers behave…

iWave Telematics Control Unit (TCU iW-G26) specifications:

Processor – Arm Cortex-A7 based CPU @ 792MHz (likely NXP i.MX 7ULP)
System Memory – 256MB DDR3L SDRAM
Storage – 4GB eMMC Flash
Connectivity
- 4G LTE Cat 4, Cat 1, Cat M1 (eMTC)
- 802.11b/g/n Wi-Fi 4 or 802.11b/g/n/ac Wi-Fi 5 (Hotspot & Station mode)
- Bluetooth 5.0
- GNSS – GPS/A-GPS receiver with antenna
Sensors – 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer
OBD Features & Protocols
- 12V Power Input from TCU Port
- USB 2.0 device
- CAN
  - 1x HS CAN bus
  - J1962 compliant OBD II Protocol: ISO 15765-4 CAN protocol support in TCU Port
  - Optional LS CAN bus
  - Optional CAN FD bus
- 4x GPIO’s (2x digital IN, 2x digital OUT)
- Power LED, status/user LED
- Optional Microphone
- Micro SIM socket (or optionally Nano SIM or eSIM)
Misc – Battery for anti-theft alarm
Temperature Range – -40°C to +85°C (excluding battery); battery when discharging: -20°C to +60°C; battery when charging: 0°C to 45°C
Dimensions – Around 106 x 87 X 28.5 mm (approximate)
Certifications – CE/FCC

The device runs Linux 4.1.15, supports FOTA updates, and sends GPS, sensors, and CAN data over 4G using MQTT protocol to the customer’s chosen cloud service. WiFi and Bluetooth are probably only used for setting up the device. Alternatively, for systems without 4G LTE, they could be used to transfer the data at bus stops, or when a user is back home.

iWave Systems Telematics Control Unit appears to be available now, and you can request a quote with your specific requirements via the product page.
