Standard IoT Gateway with ARM i.MX8M Plus Quad-Core Cortex-A53 Supports Two CAN FD Ports

Posted by Industry News on

AAEON SRG-IMX8P Standard IoT Gateway with ARM i.MX8M Plus Quad-Core Cortex-A53 1.6GHz Processor

Aaeon, a manufacturer of reliable and high-quality computing platforms, introduced their SRG-IMX8P IoT gateway solution with two CAN FD interfaces, bringing extended connectivity and utility across vertical markets.

It is powered by Arm NXP i.MX8M Plus quad-core Cortex-A53 and Cortex-M7 processors with 8 GiB of onboard DDR4, the device reduces object detection time to 13 msec via a Neural Processing Unit (NPU). It also achieves real-time multi-camera classification and speech command recognition with its two-channel Image Signal Processor and Machine Learning Accelerator. This architecture is suited for smart-city applications such as traffic management, where high-speed object detection and image processing are required.

The gateway supports two CAN-FD, two 1-Gbit/s Ethernet, two USB 3.0 ports, and an HDMI 2.0a display slot. Its USB and LAN ports support cameras and sensors. At the same time, the CAN-FD slots enable users to transmit and receive sensor data, with its HDMI connection offering an avenue for visual analysis output.

Considering the requirements of environments in which smart city and Industry 4.0 applications, the gateway operates to be flexible, durable, and reliable. An operating temperature range of -20 °C to +70 °C and a fan-less mechanism allow continued operation in harsh environments. The power input range of 9 VDC to 36 VDC delivers protection against fluctuating power supply sources. The Linux Debian operating system is pre-installed on the device.

Teensy 4.0 Triple Board With Two CAN 2.0B And One CAN FD Port With 240x240 IPS LCD And MicroSD

Teensy 4.0 Triple Board With Two CAN 2.0B And One CAN FD Port With 240x240 IPS LCD And MicroSD

The Teensy 4.0 Triple CAN Bus Board with 240x240 IPS LCD And MicroSD is a Teensy 4.0 board with triple CAN Bus connections, two Classical CAN 2.0B, and one CAN FD. It can be powered by an external +12 VDC power supply with reverse voltage protection. Also included is a 240x240 wide-angle IPS TFT LCD display with microSD holder.

The Teensy 4.0 is an Arduino-compatible board with an Arm Cortex-M7 microcontroller running at 600 MHz. The board is compatible with the Arduino IDE and the Arduino library. In most cases, code written for another Arduino board works with a minimum of changes on a Teensy. As the name implies, the board is tiny. For example, the current form factor is only about 18 by 36 millimeters. However, do not let the size mislead you; these boards pack a ton of functionality. For example, the new Teensy 4.0 features a megabyte of RAM, two megabytes of Flash, a bevy of I/O options, cryptographic support, a hardware floating-point processor (FPU), and a built-in real-time clock (RTC).
