Mouser adds Semtech’s LoRa transceivers for LPWAN and IoT applications

Wed, May 16, 2018

Continuing its new product introduction (NPI) mission, Mouser Electronics has added the SX1261 and SX1262 LoRa transceivers from Semtech.

Designed for extended battery life, the SX126x transceivers have just 4.2mA of active receive current consumption. The sub-GHz radio transceivers are suitable for long-range RF wireless applications and are fully compliant with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance.

The Semtech SX1261x transceivers support LoRa modulation for low power wide-area network (LPWAN) applications, as well as (G)FSK/MSK modulation for legacy applications. They include a new spreading factor of SF5 for dense networks, adds Mouser. The SX1261 can transmit up to +15dBm, and the SX1262 can transmit up to +22dBm with efficient, integrated power amplifiers.

The SX126x devices expand network coverage while reducing the receive-mode power consumption to just 4.5mA, this is 50 per cent less than the previous generation, notes Mouser. This extends the battery life of the LoRa-based sensors by up to 30 per cent. It also opens up many new uses for improved connectivity with IoT sensor applications.

The SX126x offer global continuous frequency coverage from 150 to 960MHz, covering all major sub-GHz ISM bands. Both radio devices are suitable for systems targeting compliance with radio regulations including, but not limited to, ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements, and the Japanese ARIB T-108. The SX1262 transceiver is supported by the SX1262DVK1CAS Development Kit, also available from Mouser.

Semtech’s SX1261 and SX1262 LoRa transceivers are now available in a compact 4.0 x 4.0mm package that is 45 per cent smaller than the current generation. Target applications are IoT and wireless projects, including smart meters, agricultural sensors, asset tracking, building automation, streetlights, safety and security sensors, healthcare, and robotics.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Mouser Electronics’ website is continually updated and offers advanced search methods to help customers quickly locate inventory. It also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.

Rutronik adds ‘fastest’ time-of-flight sensor from STMicroelectronics

Tue, May 15, 2018

The VL53L1CXV0FY/1 from STMicroelectronics is claimed to be the fastest, miniature time-of-flight (ToF), laser-ranging sensor. It joins the FlightSense and is now available from Rutronik. It has long-distance accurate ranging up to four metres and fast ranging frequency up to 50Hz.

The VL53L1CXV0FY/1 is particularly well suited for applications where user detection is required, e.g. smart home and smart lighting in target applications such as autonomous devices like service robots, drones, smart shelves and vending machines as well as gesture recognition and laser-assisted autofocus systems.

The sensor’s dimensions are 4.9 x 2.5 x 1.56mm. The VL53L1CXV0FY/1 sensor integrates a SPAD receiving array, a 940nm invisible Class1 laser emitter, physical infra red filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options. Unlike conventional IR sensors, the VL53L1CXV0FY/1 uses ST’s latest generation ToF technology that allows absolute distance measurement whatever the target colour and reflectance, explains Rutronik.

It is possible to program the size of the region-of-interest on the receiving array, allowing the sensor field-of-view of 27 degrees to be customised. Setting a specific region of interest position can provide multi-zone operation control from the host. Additionally, the VL53L1CXV0FY/1 is pin-to-pin compatible with the VL53L0X FlightSense ranging sensor.

The VL53L1CXV0FY/1 can be hidden behind a selection of cover window materials and colours allowing designers to integrate them creatively into devices. The sensor provides a standard two-wire I²C interface with up to 400kHz and works with a single power supply (2v8).

For a fast design-in process, ST offers a software driver and code examples for turnkey ranging.

Rutronik UK operates as an independent company with a team of highly qualified employees with broad experience of the electronics industry. Parent company Rutronik Elektronische Bauelemente GmbH is one of the leading broadline distributors for semiconductors, passive and electromechanical components as well as storage technologies, displays and boards and wireless products. Rutronik primarily targets automotive, medical, industrial, home appliance, energy and lighting markets.

Integrated connected car module is scalable

Mon, May 14, 2018

Targeted at the global automotive industry, the Laird Modular Automotive Connectivity (MAX) module is believed to be the first fully integrated connected car platform.

The integrated and scalable module is for secure mobile connectivity and automotive Ethernet for reliable internet use inside and outside the vehicle.

Laird MAX has been introduced worldwide and brings together communications technologies, an open software concept, a Linux-based security module, and Laird’s integrated antenna system.

MAX enables a range of services for safety and comfort, explains Laird, from driver-assisted navigation, advanced diagnostics for maintenance, theft protection and over-the-air software updates that can be scaled to meet the needs of automakers and their customers.

Worldwide sales of connected cars are expected to reach 72.5 million in the next five years, according to industry analyst IHS Markit, with almost 70 per cent of all passenger vehicles sold around the globe will be exchanging data with external sources, bringing new services and new business models to bear in automotive markets by 2023.

The modularisation of MAX enables automakers to have a short time-to-market compared to tailor-made solutions, says Laird. It can be integrated into a Laird system solution, including control unit and antenna, and used for external service providers as the basis for a back-end connection or for app development.

Its scalability means it can cater for customers who only need networking for small batches.

Applications that can be implemented on MAX include internet gateway functionality, a remote diagnostic tool, a remote-control system, location functions, and driver statistics. It can be used to set up a wide range of services for OEMs, fleet operators and insurance companies.

MAX enables a connected vehicle to continuously and securely stream and share data with multiple wireless devices and applications inside and outside the vehicle’s immediate environment. It can serve as a communication basis for networked and autonomous vehicles in smart cities, as well as with trucks, fork-lifts or machines in networked logistics or for smart farming.

The use of custom features limits the number of components and their weight, to make MAX is environmentally-friendly, says Laird. By optimizing the energy management, the power consumption is reduced, which is a differentiation advantage especially for electric vehicles.
