Microcontrollers, sensors, analogue and power devices are combined with Cat-M1 cellular modules by Renesas Electronics to enable end-to-end cloud connectivity.

Renesas has announced two cloud development kits, the CK-RA6M5 and CK-RX65N, for the RA and RX Families of 32bit microcontrollers. The cloud kits are the first to be equipped with Renesas’ RYZ014A Cat-M1 module, a certified LTE cellular module that can establish wireless connection between microcontrollers and cloud services quickly and securely without a gateway.

Armed with these cloud kits, users can rapidly develop IoT cloud products and solutions without having to design their own complex circuitry and software stacks, Renesas explained.

The kits include the RYZ014A Cat-M1 Pmod module, multiple sensors, a high-performance microcontroller, hardware-based security and a reliable software stack.

The cloud kits are ready to connect to global cloud service providers such as AWS Cloud and IoT services. Both kits are designed to run on AWS (Amazon Web Services) FreeRTOS for CK-RA6M5 using FSP (Flexible Software Package) and CK-RX65N using RDP (RX Driver Package). Once connected to AWS IoT Core, the kits have access to many cloud and IoT services from AWS for data analytics and IoT device management.

“With Renesas’ first cellular Cat-M1 module, we are adding ubiquitous cellular connectivity to our cloud solution offerings, providing our customers more flexible and reliable cloud connectivity options,” said Roger Wendelken, senior vice president in Renesas’ IoT and Infrastructure business unit. Engineers can focus on designing IoT systems that can be adopted in a variety of applications such as building and home automation, smart metering, healthcare and industrial applications, Wendelken added.

“Mobile cloud computing is leading a new era for data storage and processing, especially now that cellular IoT devices have become so pervasive,” said Georges Karam, CEO of Sequans Communications. “Packed with on-board sensors and the Cat-M1 module powered by Sequans’ Monarch technology, Renesas’ cloud kits will be ideal platforms for evaluating and deploying mobile cloud applications for wireless IoT systems.”

The CK-RA6M5 and CK-RX65N both have identical hardware and software features and a common dashboard user interface to access real-time cloud data.

In addition to the Cat-M1 RYZ014A wireless module, the kits also provide an option to use Ethernet to securely connect to cloud when the Cat-M1 network is not available. Renesas plans to offer more wireless connectivity options in the future.

The CK-RA6M5 and CK-RX65N kits are available from Renesas worldwide distributors.

LoRaWAN geolocation module are compact for asset tracking

Wed, Jun 15, 2022

Low power indoor-outdoor geolocation company, Abeeway, partnered with Murata to develop the LBEU5ZZ1WL geolocation module. It is a low power wide area network (LPWAN) module, designed to maximise battery life and is claimed to be sensitive and flexible enough to build customised, inexpensive, IoT tracking devices. Applications are both indoors and outdoors and include asset recovery, traceability, inventory management and theft prevention.

The modules integrate LoRaWAN [long range WAN] connectivity. The low power technology has become the de-facto standard for connectivity over public and private networks. In addition to a dual-core, multi-protocol wireless microcontroller, the modules contain a high-performance multi-constellation GNSS receiver (GPS, GLONASS, Beidou and Galileo) and support a patented low-power localiser performance (LP) mode.

On-board Bluetooth Low Energy (BLE) 5.2 (Bluetooth SIG cert is underway) connectivity allows for short range communication with smartphone apps and other devices for applications such as contact tracing or monitoring BLE tagged equipment. The multi-technology modules have full power-optimised FreeRTOS, drivers and a LoRaWAN stack.

“The key requirement is to minimise time to market for device manufacturers embracing LoRaWAN for industrial or consumer applications. The new geolocation module . . . brings a market-ready reference for anyone wanting to develop a customised tracking device,” said Olivier Hersent, CEO at Actility, Abeeway’s parent company.

The module implements Semtech’s latest transceiver and ST’s STM32 wireless microcontrollers for security features and device management for LoRaWAN deployment, he added.

According to Akira Sasaki, general manager – connectivity module marketing, Murata: “This exciting collaboration greatly simplifies the development of new LoRaWAN tracking devices and offers customers faster time to market by minimising BoM [bill of materials] size, TCO [total cost of ownership] and complexity”.

The modules are designed and manufactured by Murata Manufacturing. The company encapsulated an array of enabling devices within one system in package (SiP). The compact module helps engineers save valuable board space for space-restricted tracking applications, as well as helps them to reduce certification risk and budget, test time and cost for mass production, said Murata.

The Abeeway-Murata Geolocation Module with a fully featured evaluation kit will be available in production quantities after September 2022. The modules will be demonstrated at Embedded World (21 to 23 June) in Nuremberg, Germany and LoRaWAN World Expo in Paris, France (6 to 7 July).

ToF sensors advances use less energy or double range

Mon, Jun 13, 2022

Metasurface lens technology is introduced by STMicroelectronics in its second generation, FlightSense multi-zone direct time of flight (ToF) sensor. The VL53L8 uses less energy and can range twice as far as existing products, said the company.

The FlightSense ToF ranging sensor for smartphone camera management and augmented reality / virtual reality (AR / VR) offers up to four metres in range in all zones indoors, while reducing the power consumption by half compared to the previous-generation device, operating in common conditions.

The ToF sensor’s metasurface lens technology and power-efficient architecture reduces battery loading, extends camera autofocus ranging and enhances scene-understanding features, explained Eric Aussedat, executive vice president and general manager of the imaging sub-group within ST’s Analog, MEMS and Sensors group.

What is claimed to be the world’s first optical metasurface technology was developed in partnership with Metalenz. It enables optical systems to collect more light, provide multiple functions in a single layer and deliver new forms of sensing in smartphones and other devices, in the form factor of a single, compact package, added ST.

This second-generation ranging sensor incorporates an efficient optically diffractive metasurface lens technology, manufactured at the company’s 300mm fab in Crolles, France. The VCSEL driver is three times more capable than the previous generation with an efficient VCSEL, enabling the VL53L8 to deliver twice the ranging performance of earlier VL53L5 or reduce power consumption by 50 per cent, when operating in comparable conditions. It delivers this performance while maintaining the same field of view and discrete output-ranging zones (4×4 at 60 frames per second or 8×8 at 15 frames per second).

The module embeds a high output 940nm VCSEL light source, an SoC sensor with an embedded VCSEL driver, the receiving array of SPADs (single photon avalanche diodes) and a low power, 32-bit microcontroller core.

The VL53L8 adopts a metasurface lens technology in both the transmit and receive apertures and delivers 16 or 64 discrete ranging zones with stable and accurate ranging, said ST.

The sensor is housed in a single reflowable component that offers 1.2V and 1.8V I/O compatibility for ease of system integration. It is also claimed to significantly reduce the host processor loading over the demands of the first-generation sensor.

Like all other FlightSense ToF proximity sensors, the VL53L8 retains an IEC 60825-1 Class 1 certification and is fully eye-safe for consumer products with an advanced lens detach detection system.

The VL53L8 can be used in smartphones and tablets in both user-facing, like object tracking and gesture recognition, and world-facing applications, such as laser-autofocus, camera selection, touch-to-focus, and flash dimming. It is also suitable for accessories in personal electronics equipment (e.g. smart speakers and AR / VR and mixed reality (MR). The VL53L8 will deliver even greater benefit to these features in low-light conditions, said ST. It can also support indoor/outdoor detection and smart-focus bracketing, as well as consumer lidar, where depth mapping is required.

The VL53L8 is entering mass production now for select customers.
