STMicroelectronics has announced the availability to all–including students, makers, and budding engineers and computer scientists–of the online “Introduction to Embedded Systems with SensorTile” course. With a curriculum developed by Professor William Kaiser at the University of California, Los Angeles (UCLA), and used to teach his freshman engineering class, the online course resources provide a foundation to understand the fundamentals of a sensor-based Internet of Things (IoT)-enabled embedded system. Professors at other universities are also encouraged to adapt and contribute to the course.
The introductory course of 8 self-paced tutorials is designed around ST’s SensorTile, a unique real-time IoT-enabled embedded system on a postage-stamp-sized module. The tiny 13.5 mm x 13.5 mm module combines a high-performance, low-power STM32 Arm-Cortex-M-core microcontroller, 5 valuable MEMS (Micro-Electro-Mechanical Systems) sensors—an inertial sensor containing an accelerometer and gyroscope, an eCompass, a pressure sensor, and a microphone—and a Bluetooth network processor. A kit with the module, cables, cradle and a battery is available from major resellers for about $80.
The joint effort with ST makes the 8 tutorials freely available online, with a full complement of documentation, open-source algorithms and development solutions, and unfettered access to a growing user forum. Anyone interested in learning more about the tutorial or purchasing a SensorTile kit should visit the web site www.st.com/sensortile-edu). Additional information is available, as well, on the ST blog: blog.st.com/introduction-embedded-systems-sensortile-online-course/

STMicroelectronics and Objenious are working together to accelerate the connection of IoT nodes to LoRa networks. ST’s development kits certified on the Objenious network are available now, greatly reducing R&D effort and time to market in the creation of new LoRa devices.
STM32 Nucleo LoRa kits are now certified and available to developers through ST sales channels.
LoRAWAN is a Low Power Wide Area Network (LPWAN) based on LoRa technology that is opening up a world of possibilities to create networks of connected devices ideal to address a broad range of IoT applications. The benefits of LoRa especially suit applications where nodes have limited power capability, can be difficult to access, and data transfers don’t require high bandwidth. LoRa can target a wide spectrum of applications such as tracking, proactive maintenance, and many others. Industry analysts estimate there will be tens of billions of connected devices deployed in the world by 2020.
Objenious launched and operates the first LoRa network in France, with more than 4,200 antennas deployed around the country. Leveraging the network know-how inherited from Bouygues Telecom, Objenious now proposes its LoRa network, platform, and services for LPWAN IoT to partners and customers locally and internationally thanks to roaming agreements.
STMicro helps developers by providing tools and software libraries that aid the STM32 MCU-based embedded design as part of its freely available STM32 Open Development Environment (ODE). By integrating Objenious’ network access software on top of the STM32 ODE, developing connected devices is even easier. STM32 Nucleo LoRa kits are now certified and available to developers through ST sales channels.

Antenova has announce a new antenna, Grandis, part number SR42I010. It is an SMD antenna that is physically smaller yet provides enhanced performance in the 863-870 MHz and 902-928MHz bands. It directly targets the growing number of M2M and IoT applications using the LPWAN protocols. With Grandis, Antenova has reduced the footprint of the LPWAN antenna to 12.0 x 11.0 x 1.6mm, while also enhancing the antenna’s performance. Grandis is a low-profile antenna which uses a ground plane to radiate, and is designed to be placed in the corner of the PCB.
Antenova endeavours to give PCB designers the benefit of flexibility in the positioning of the antenna within a design, so the Grandis antenna is supplied is two versions, Left and Right, to give designers a choice of locations for the antenna on a PCB. LPWAN is an increasingly popular choice for IoT and smart city applications because it uses less power, which means that the batteries within individual devices will have an extended life. Antenova’s Grandis antenna covers the newer LPWAN standards for connected devices in IoT and smart cities: LoRa, SigFox and Weightless-P. Grandis is suitable for all applications in the 863-870 MHz and 902-928MHz bands, so it could be used in industrial, scientific and medical applications, smart metering, network devices, manufacturing automation, agricultural and environmental monitoring and consumer tracking, worldwide.
