RS Components ships Microchip’s AVR Google Cloud development board

Distributor RS Components has announced the availability of Microchip’s AVR microcontroller IoT development board for Google Cloud. It is designed to enable engineers to achieve the fast prototyping of cloud-connected devices within minutes, adds the company.

Microchip’s AVR-IoT WG development board integrates the ATmega4808 AVR-based microcontroller, with a secure-element IC and a fully certified Wi-Fi network controller. The board works in conjunction with Google Cloud IoT Core, which offers an artificial intelligence and machine learning-based infrastructure in which is collects, processes and analyses data.

Developers can add cloud connectivity to a device via a free online portal at http://www.AVR-IoT.com. Microchip’s AVR devices are supported in the MPLAB X integrated development environment (IDE), meaning that once an IoT device is connected to Google Cloud, engineers can develop and debug their application in the cloud using rapid development tools such as Microchip’s MPLAB Code Configurator (MCC) or Atmel Start.

The AVR-IoT development board’s ATmega4808 processor is an eight-bit microcontroller that features core independent peripherals (CIPs) designed to deliver low power consumption. Sensing and actuation features make the board suitable fro real-time sensing and control applications.

An ATECC608A crypto-authentication IC delivers a trusted and protected identity for secure authentication of devices for the board. The crypto-authentication IC is delivered pre-registered on Google Cloud IoT Core and is ready for use with zero touch provisioning, claims Microchip. There is also a fully certified IEEE802.11-b/g/n IoT network controller, the ATWINC1510, which connects via an SPI.

Developers can use the board to create cloud-connected applications without requiring expertise in communications protocols, security or hardware compatibility, explains RS Components. In addition, they do not have to deal with security vulnerabilities or face the challenges generated with the use of large software frameworks and real time operating systems (RTOS).

The AVR-IoT WG development board (AC164160) is shipping from RS in the EMEA and Asia Pacific regions.

Farnell element14 offers Arm-based dev board to accelerate AI design

Availability of the Ultra96 development board has been announced by distributor, Farnell element14. The Arm-based Ultra96 development board was jointly created by Avnet, Xilinx, and 96Boards and is based on the Linaro 96Boards Consumer Edition specification. It features the Zynq UltraScale+ MPSoC with 2Gbit (512M x32) LPDDR4 RAM from Micron, 802.11b/g/n Wi-Fi and Bluetooth 4.2, one USB 3.0 Type Micro-B upstream port (for a device) and two USB 3.0 and one USB 2.0 Type A downstream ports (for hosts).

According to Farnell, it provides developers with a powerful environment to simplify machine learning. The 96Boards’ specifications are open and define a standard board layout for development platforms.

The Ultra96 is designed to offer a range of peripherals and has programmable logic acceleration engines for ‘complexity with simplicity’ according to the company. The Ultra96 allows software developers to accelerate the development process for applications that require intense processing and high performance in areas such as artificial intelligence (AI), machine learning, virtual reality, the IoT and industrial control.

Cliff Ortmeyer, global head of solutions development for Premier Farnell and Farnell element14 said: “The Ultra96 board combines Arm processing with programmable logic in a convenient, low-cost and expandable board which showcases a wide range of potential peripherals and acceleration engines that will help design engineers counter software bottlenecks.”

The Ultra96 boots from the industrial rated Delkin 16GB MicroSD card (supplied with the Ultra96 board), and is preloaded with Embedded Linux. Design engineers can connect to the Ultra96 through a web server using its integrated wireless access point capability, or use the pre-loaded Embedded Linux plus Enlightenment Desktop via integrated Mini DisplayPort video output. Multiple application examples and on-board development options are provided as examples.

The board includes four user-controllable LEDs. Design engineers can also interact with the board through the 96Boards-compatible low-speed and high-speed expansion connectors by adding peripheral accessories such as those included in Seeed Studio’s Grove Starter Kit for 96Boards.

The Ultra96 development board is available from Farnell element14 in EMEA, Newark element14 in North America and element14 in Asia Pacific.

Mouser offers TI’s digital humidity and temperature sensor for smart devices

Distributor Mouser Electronics has added Texas Instruments’ HDC2080 humidity and temperature digital sensor. It offers high accuracy and low power consumption in a compact package, reports the distributor and is suitable for a range of IoT and environment monitoring applications.

The TI HDC2080 humidity and temperature digital sensor is a capacitive-based device that uses an integrated heating element to dissipate moisture and condensation. The sensor integrates multiple digital features, allowing for the use of programmable input thresholds to deliver system wake-ups and alerts without needing to rely on a microcontroller to monitor the system. The HDC2080 sensor’s low power consumption allows developers to place their microcontrollers in deep sleep mode, because the sensor can initiate measurements without input from a microcontroller. The high-performance sensors offer a typical humidity accuracy of ± two per cent and a typical temperature accuracy of ±0.2 degrees C.

The sensor features an auto-measurement mode to initiate humidity and temperature measurements, enabling efficient performance in applications with power-budget restrictions. The sensor is designed for battery-operated systems and supports a supply voltage range of 1.62 to 3.6V. With an operating temperature range of minus 40 to 85 degrees C, the sensors can be safely used in applications such as home appliances, smart home devices, smart thermostats, HVAC systems and inkjet printers.

The HDC2080 humidity and temperature digital sensor is supported by the HDC2080EVM, a simple plug-and-play platform that features an MSP430F5528 microcontroller and a USB interface, for communication between the HDC2080 sensor and a PC. The module’s included software graphically logs humidity and temperature data, and the module also allows access to the sensor’s configuration registers.

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. Mouser.com also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.
