Communications Technology

Connectivity is a key feature of modern embedded products. There’s a wide range of communications modes that can be used, but which is the best for your design? Should you use a wireless technology such as Wi-Fi or Bluetooth and, if so, which one should that be? Or would wired communication, such as Ethernet, be the best way forward?

In this section, New Electronics reviews the latest communications technologies and brings visitors to the website information on how these technologies are being applied.

Large pitch board to board connectors

GCT has extended its range of board to board connectors with two families: the BH, with a 3.96mm pitch, and the BK, with a 5.08mm pitch. According to the company, the additions feature the largest pitch sizes available for standard products.

Flexible displays can be read in daylight

Flexible displays manufactured by Plastic Logic are now available from Review Display Systems (RDS). The glass-free electrophoretic active matrix displays are shatterproof, bendable and readable in daylight.

Direct connector with push-in spring connection

Contact SKEDD PCB connectors from Phoenix are said to feature an innovative plug-in technology and can be mounted directly onto PCBs in any position without using tools. The SDC 2.5 series and SDDC 1.5 series are now available in Europe from TTI.

PCIe switch provides fabric connectivity

The Switchtec PAX advanced fabric Gen3 PCIe switch from Microsemi is said to provide fabric connectivity for scalable, multi-host systems as well as ‘just a bunch of flash’ supporting single root I/O virtualisation (SR-IOV), NVMe and multi-function endpoints.

Expanded beam fibre optic connector for tough environments

An expanded beam fibre optic connector from HARTING is said to provide high bandwidth transmission in harsh environments, such as in tunnel drilling and mining applications – where according to HARTING industrial Ethernet over fibre optic cable is becoming the transmission medium of choice.

Bluetooth mesh SDK unveiled

Nordic Semiconductor has introduced a software development kit (SDK) which allows engineers to develop Bluetooth mesh based applications. The SDK, which includes the company’s first release of its Bluetooth mesh software stack, is compatible with Nordic’s nRF51 and nRF52 series SoCs and the S110, S130, and S132 SoftDevices.

Compact TFT display has Rugged+ performance

The 4.2in Rugged+ thin film transistor (TFT) display from LCD manufacturer KOE is said to feature the latest generation of in-plane switching (IPS) technology, wide quarter VGA resolution of 480 x 272 pixels, a 16:9 wide aspect ratio and an extended operating temperature range.

Antennas work on metal surfaces without de-tuning

A family of antennas from Antenova has been engineered to operate without de-tuning on metal surfaces or where the product housing is mainly metal. According to the company, these situations normally make it difficult for an antenna to operate.

First 2.5 and 5Gbit/s octal Ethernet transceiver

Marvell has announced the Alaska M 88E2180 Gigabit Ethernet transceiver, which it claims to be the first compatible with both the IEEE 802.3bz standard and the NBASE-T AllianceSM specification for 2.5 and 5Gbit/s operation over CAT5e cables.

Solution to maintain colour stability and lumen output

The AS7220 Smart Lighting Manager from ams uses closed-loop sensing to maintain accurate correlated colour temperature (CCT) and lumen output. The company claims the solution could enable a new generation of higher quality LED-based lamps and luminaires.
