Linux Based LTE Gateway For IoT Applications Supports CAN Bus Interface
Posted by on
IoTmaxx (Germany) introduced its Maxx GW 4100 4-G mobile radio gateway with CAN Bus interface. The „always-online" functionality establishes a connection to the device autonomously or reestablishes the link in case of a failure. The two integrated SIM card slots provide mobile network operator redundancy. The received data is buffered in the internal memory of the gateway. Interfaces include CAN Bus, Ethernet, USB, EIA-232, EIA-485, two analog I/Os, and an SD-card slot. A GNSS (Global Navigation Satellite System) receiver is integrated as well.
The operating system is Linux, allowing programming of the gateway using C, C++, and Python. Furthermore, pre-defined or customizable programming functions are offered. A secure, encrypted connection with the device is possible via the VPN (Virtual Private Network) from OpenVPN. Therefore, the gateway is accessible only by an authorized end-user. Software updates for the Linux operating system, applications, and configurations are accomplished via the IoTmaxx's centralized “over-the-air” firmware updating service. Suitable antennas, power supply, connectors, and an optional security chip are also available.
Raspberry Pi 3 B+ System With Dual Isolated CAN Bus Interface
Our Raspberry Pi 3 System With CAN Bus Interface (PiCAN2) comes with a pre-installed Raspbian operating system.
The PiCAN2 DUO ISO board provides two independent isolated CAN-Bus channels for the Raspberry Pi. It uses the Microchip MCP2515 CAN controller in combination with the Texas Instruments ISO1050 isolated CAN transceiver. Connections are made via 4 way screw terminal plugs.
There is an easy-to-install SocketCAN driver, and programming can be accomplished in C or Python.
