AutoPi 4G Telematics Unit With OBD-II CAN Bus Port For Fleet Management

The TMU Pi3 telematics unit by Autopi (Denmark) utilizes the Raspberry Pi 3 Model A+ SBC, and it connects to in-vehicle CAN Bus networks via the OBD2 port.

AutoPi Telematics Unit

The device uses the 1,4-GHz Broadcom BCM2837B0 SOC with Cortex-A53 64-bit quad-core processor, including 512-MiB SDRAM and a 32-GiB micro SD card with installed Raspbian Jessie operating system and Autopi Core software. 

Supported CAN-based higher-layer protocols include ISO 15765-4 (diagnostic over CAN), SAE J1939, etc. Wifi, Bluetooth, and 4G/LTE cellular network provide wireless connectivity. The TMU Pi3 is upgradeable to the Raspberry Pi4 if additional computing power and Ethernet support are necessary.

The unit features a GPS receiver, an HDMI (video output) interface, an audio jack, built-in speakers, a micro USB port, and 18 programmable GPIO (general purpose input/output) pins. It also carries a 3-Axis accelerometer, and it is possible to expand the TMU with a 3-axis gyroscope. Two LEDs indicate the power and status of the device. 

The dimensions are 137 mm x 36mm x 66mm, and it operates with a power supply of up to 35VDC, which is suitable for use in trucks. A built-in power management system prevents the vehicle’s battery from being drained when the TMU is left plugged in for extended periods. The operating temperature can range from -20 °C to +70 °C.

In combination with the fleet and device management software, Autopi Management Cloud tracks the connected vehicles. The data can be visualized and diagnosed on a PC, a mobile device, or the cloud.
