A 3U CompactPCI serial CPU board by Duagon features the 11th generation Intel Core and Intel Xeon W-11000E series processors / Tiger Lake-H CPUs. The G28 has up to eight cores and up to 64Gbyte RAM and is suitable for embedded computing for rail systems (onboard and trackside) as well as for the medical and critical automation industries. 

Optional 10Gbit Ethernet interfaces allow for high data throughput and direct connection to the network backbone.

For a robust performance in harsh environments, DRAM (up to 64Gbyte DDR DRAM with error code correction or ECC) is soldered to the board, the components are underfilled and additionally coated to guarantee optimum shock and vibration resistance and durability against harsh environmental conditions. The CPU is scalable from 25 to 45W TDP (thermal dynamic performance) and four to eight cores allows operation in ambient temperatures of up to +85 degrees C with active cooling. According to Duagon, a single board can cover different environmental conditions and market applications.

In onboard rail applications, the G28 can be used as central maintenance and virtualisation platform and main computing unit for passenger Wi-Fi and internet access. As part of a rail wayside server system, the SBC can be used for condition monitoring and in medical applications, the G28 can be used in surgical robots. It can also be used in factory automation for motion control and robotics in industrial automation.

For system security, a Trusted Platform Module (TPM 2.0) is assembled. This provides the G28 support for remote device authentication, measured boot, and secure updates. There is also an independent board management controller (BMC) which monitors onboard voltages, current and temperature. It also performs dedicated tasks like external watchdog management, power supply control and reset handling.

The G28 features three RJ45 or two M12 Ethernet front connectors, one USB 3.2 Gen 2×1 connector and one USB-C connector for one USB 3.2 Gen 2×1 and one DisplayPort. Main backplane interfaces include four SATA (6Gbit), eight PCIe 3.0 root ports with lane configurations of one, four or eight, and two 1Gbit Ethernet ports.

The SBC is supported by Linux Yocto Project, Windows 10 IoT Enterprise 64-bit as well as real time operating systems (RTOS) that supports Intel’s multi-core architecture. 

Duagon also offers long-term availability of the components for a minimum of 10 years. The G28 is backwards compatible to the predecessor products G25, G25A and G23.

The fully qualified G28 will be available from September 2022.

Enhancements to the 6LoWPAN mesh network by Radiocrafts support low power, robust and scalable operation, said the company.

Upgrades to its RIMM industrial IP mesh include improved battery lifetime by more than 50 per cent and sleep current as low as 2.5 microA.

Radiocrafts has also improved maximum data throughput to the border router (gateway) by a factor of 20 and the network robustness has been improved to 99.99 per cent with synchronised channel hopping and frequency agility.

Other improvements are Modbus and RS485 support to meet industrial control market requirements and additional compliance to radio regulations in India and Vietnam. 

There are now pulse width modulation (PWM) outputs for analogue control and multi-cast (one-to-many) performance improvements reducing on-air communication time.

There is also Microsoft Visual Studio Code support for a more user-friendly coding experience, said Radiocrafts.

Since its release in 2018, RIIM has been used as an embedded RF system designed to be an all-inclusive, easy-to-use, long range wireless communication mesh using 6LoWPAN. This is a lightweight version of IPv6 allowing the user to access each sensor or controller from the internet using IP addressing. 

The radio protocol uses IEEE 802.15.4 g/e providing symmetrical bi-directional communication with short transmission pulses that enable dense networks with high reliability and very low power consumption. A customer developed application software can run on top of the embedded operation system, reducing overall cost and improve integration, added Radiocrafts.

RIIM is used in a variety of applications including solar panel and inverter installations, smart street lighting, smart irrigation, emergency lighting, building automation, and other industrial sensor and control applications, said the company. It is not require a license or subscription, and is very low power. Hardware and software development kits are available now.

Radiocrafts designs and manufacturers RF modules. Its standard RF modules provide compact, easy-to-use, low cost, low power RF for a large number of wireless applications using license-free ISM bands. Using these modules OEM manufacturers without RF design knowledge can easily add wireless technology into their design, reducing time-to-market, cost of design, test and compliance approvals, said the company. Radiocrafts also offers custom and application specific product development, supporting customers from initial project ideas to volume product delivery.
