NB-IoT Module is Ready for 3GPP Release 14 and 5G

U‑blox has announced the SARA‑N3, a multi‑band NB‑IoT module that supports a preliminary set of 3GPP Release 14 features (LTE Cat NB2). The SARA‑N3 is available in two variants: one dedicated to China and another that can operate across multiple bands on any NB‑IoT network globally. The U‑blox firmware‑over‑the‑air (uFOTA) client/server solution with Lightweight M2M (LwM2M) allows SARA‑N3 to be remotely provisioned with additional features.

LwM2M is a more lightweight solution as compared to OMA‑DM. That means it is well suited for providing critical firmware updates to IoT devices. In this way, SARA‑N3 can ultimately become 5G compliant. SARA‑N3 also supports the creation of dynamic LwM2M objects. That enables users to do feature customization by scripting their own configurable objects.

The SARA‑N3 provides a comprehensive set of features and protocols that NB‑IoT‑based applications will benefit from, including TCP, HTTPS, CoAP, DTLS and MQTT. With its ultra‑low power consumption profile and the ability to configure voltage domains, the module is optimized to operate on a single cell primary battery for 10+ years, eliminating the need for frequent maintenance visits. Other features include a “last gasp” function that lets the module send one last message should the power fail unexpectedly and protection against software attacks by detecting potential jamming signals.

U‑blox manufactures according to ISO/TS16949 professional grade specifications. This approach incorporates 100% automated x‑ray and optical inspections, 100% outgoing test and product traceability. Together with failure analysis and product qualification criteria ensures that highly reliable products designed for long‑term operation are created.

Fanless SBC Targets Industrial IoT

Technologic Systems is now shipping its newest single board computer, the TS-7553-V2. The board is developed around the NXP i.MX6 UltraLite, a high performance  processor family featuring an advanced implementation of a single ARM Cortex-A7 core, which operates at speeds up to 696 MHz. While able to support a wide range of embedded applications, the TS-7553-V2 was specifically designed to target the industrial Internet of Things (IIoT) sector.

ts-7553-v2The TS-7553-V2 was designed with connectivity in mind. An on-board Xbee interface, capable of supporting Xbee or NimbleLink, provides a simple path to adding a variety of Wireless interfaces. An Xbee radio can be used to link in with a local 2.4GHz or sub 1 GHz mesh networks, allowing for gateway or node deployments. Either Digi or NimbleLink offer cellular radios for this socket, providing cellular connectivity for applications such as remote equipment monitoring and control. There is also the option for a cellular modem via daughter card. This allows transmission of serial data via TCP, UDP or SMS over the cellular network. The TS-7553-V2 also includes an on board WiFi b/g/n and Bluetooth 4.0 option, providing even more connectivity.

Further radio expansion can be accomplished with the two internal USB interfaces (one on a standard USB Type A connector, and the second on simple pin headers). The USB interfaces enable support for multiple proprietary networks via a dongle or USB connected device. This provides the opportunity to run mesh, LoRa, ZigBee, automotive WiFi or other protocols with the TS-7553-v2 . All of these radio options combined with the on board 10/100Base-T Ethernet create the opportunity to communicate seamlessly with up to 5 different networks simultaneously from a single point.

The TS-75553-V2 supports standard interfaces including:

  •     10/100 Ethernet
  •     TTL UART
  •     4 USB ports (3 host interfaces and, 1 device)
  •     3 RS-232 Serial/COM ports
  •     RS-485 port
  •     CAN bus
  •     Up to 5 GPIO

A Nine-Axis Micro-Electro-Mechanical System (MEMS) motion tracking device containing a gyroscope, accelerometer and compass are optional on-board in for asset management, fleet management and other applications which would require sensing motion or vibration in the environment.

A low cost monochrome 128x64px LCD with 4 button keypad is available for Human Machine Interface (HMI) applications.  The keypad offers intuitive operation using 4 tactile function keys and the LCD is ideal for simple visualization tasks, even in harsh environments.  If HMI is not a consideration compact, lightweight, rugged enclosures are available to contain your gateway in a secure fanless enclosure. Both enclosures are DIN mountable.

Technologic Systems has taken the lead in combating read/write errors to memory that can prove fatal to Operating Systems. TS-SILO is an optional feature which will provide up to 30 seconds of reserve power in the event of a power failure. This precious extra time gives the board time to gracefully power down and ensures file system integrity. Additionally, for heavy data logging applications The TS-7553-V2 is the first SBC from Technologic Systems to include Ferroelectric RAM (FeRAM or FRAM). FeRAM advantages over flash include: lower power usage, faster write performance and a much greater maximum read/write endurance, allowing a user to keep running data logs without prematurely wearing out their flash memory. Combined these two features provide you with insurance from abrupt power loss, read/write errors and startup difficulties.

Applications with strict low power requirements will appreciate the work that’s been done to reduce power consumption to less than 2 W in typical conditions and a 9 mW sleep mode. Power over Ethernet (PoE) is supported via a daughter card, if desired.

Development can begin out-of-the-box with pre-installed Linux and utilities for controlling DIO, UARTS, CAN bus, and more. A complete board support package is provided, as well as access to our software repository and online support. Third party application support can be provided via the Technologic Systems’ Partner Network.
