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.
ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module
The board comes with an onboard ESP32 WROOM-32 WiFi, Bluetooth Classic, BLE Module, and a CAN Bus port with a transceiver. Also, onboard is an RGB LED, IO pins on a 0.1" pad.
Programming is accomplished through the popular Arduino IDE connected to the USB-to-Serial converter with USB-C connector, automatic bootloader, and reset.
The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated WiFi and dual-mode Bluetooth.

To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]

The module features a 512-core Nvidia Volta GPU with 64 Tensor cores, two Nvidia deep learning accelerators, two [...]
Any SAE J1939 hardware must support SAE J1939/1x and SAE J1939/21; otherwise, they’re useless because these standards describe the CAN bus physical layer and the basic protocol features. That part is sufficiently covered (i.e., for demonstration purposes) by our CAN shield, while the cabling and connectors may not necessarily J1939-compliant. A fully functional SAE J1939 protocol software [...]
