Mon, Sep 03, 2018

Developers can take internet of things (IoT) projects from initial idea to proof of concept quickly, with the NXP Rapid IoT prototyping kit, now available from Mouser Electronics.

Rapid IoT has hardware, enhanced security and power management within a small form factor and is pre-configured with 11 NXP devices (including microcontrollers, interface, near field communication (NFC), anti-counterfeit security and sensor options. The kit is designed to support engineers in the development of a range of IoT devices, including smart appliances, wearables, home and building automation, and medical devices.

The NXP Rapid IoT prototyping kit combines a high-performance, low power NXP Kinetis K64 microcontroller based on an Arm Cortex-M4 core, and an NXP Kinetis KW41Z wireless microcontroller that enables Bluetooth low energy (BLE), Thread, and Zigbee connectivity. The modular device is versatile, with a capacitive touch sensor, six-axis digital accelerometer and magnetometer, three-axis digital gyroscope, digital pressure barometric and humidity sensor, digital ambient light sensor, and digital air quality sensor.

Pre-programmed applications enable users to quickly get familiar with the kit’s capabilities. The device features a web integrated development environment (IDE) with graphic user interface (GUI)-based programming to help users modify the device’s behaviour without having experience of embedded coding, says Mouser. Engineers can transition ideas from prototype to development with automatic source code generation for NXP’s MCUXpresso, a set of software tools including software development kit (SDK), IDE and configuration tools.

Rapid IoT is compatible with the NXP IoT Modular Gateway development platform that brings together the building blocks for secure, production-ready IoT systems including hardware, software, connectivity, security and cloud services with guidance and support. Rapid IoT is also fully compatible with the MikroElektronika Hexiwear docking station and over 400 MikroElektronika Click boards to enable a wide range of functionality for almost any IoT use case.

Sensor node SoM advances IoT development in cities

Fri, Aug 31, 2018

IoT specialist, SensiEdge now offers the SensiSub system-on-module (SoM) starter kit, describing it as a board-level IoT sensor node. It joins the company’s Bluetooth-enabled SensiBLE IoT SoM, but delivers higher range and more reliable frequency bands to penetrate obstacles and reduce interference. The SoM is suitable for IoT applications in varied locations, including smart factory, smart home, smart grid and smart city deployments.

SensiSub is based on a low power Arm 32-bit Cortex-M4 CPU with FPU, and a range of serial interfaces (including SPI, I²C, UART, ADC, CAN, USB and GPIO). The SoM combines a Spirit1 low-power RF transceiver from ST Microelectronics, offering certified sub-1.0GHz connectivity (in three frequency versions: 433, 868 and 915MHz). A suite of customisable sensors includes a three-axis accelerometer, magnetometer and digital gyroscope, plus pressure, microphone, relative humidity, ambient light, temperature and UV sensors.

SensiSub’s hardware-ready configuration provides a complete, self-contained RF platform in a small form factor (20 x 30mm) that enables wireless connectivity without prior RF expertise. The SoM is therefore suitable for a range of applications that demand rich functionality, including smart metering, industrial lighting, and home and building automation, where it can capitalise on its long range, reduced interference and low power features of the sub-1.0GHz spectrum band.

The SensiSub IoT SoM is an industrial-grade customisable module for engineers looking to design IoT products without getting involved in either hardware development or production logistics. It allows developers to focus on their own applications, domain expertise and core competencies, rather than the underlying hardware platform or production logistics when creating products for the IoT.

SensiSub fits an array of coin battery-powered applications that require integration of multiple sensors with sub-1.0GHz connectivity, without compromising on cost and power consumption, says SensiEdge. It also shares the same small form factor as SensiBle, enabling customers to develop and build prototypes and proof-of-concepts using SensiBle, before transitioning to SensiSub for deployments requiring greater range.

Mouser adds Bosch sensor for environmental data for industry 4.0

Fri, Aug 31, 2018

Distributor, Mouser Electronics, now stocks the Connected Industrial Sensor Solution (CISS) from Bosch. The Bosch CISS is a robust, multi-sensor device designed to enable internet of things (IoT) applications in harsh environments, using MEMS technology to detect vibration and acceleration and other environmental conditions.

The Bosch CISS integrates a gyroscope, accelerometer, magnetometer, temperature/humidity/air pressure sensor, microphone, and light sensor. Engineers can activate or deactivate each sensor individually and configure the sensors’ sampling rates and thresholds to suit different applications. The CISS features a 32-bit Arm Cortex-M3 microcontroller with 1Mbyte of internal flash, as well as a Bluetooth low energy radio and USB connectivity for data transmission.

The CISS provides data to optimise maintenance processes and enhance productivity, and can be integrated to a range of hardware-agnostic gateways and clouds. The device allows for monitoring of multiple conditions simultaneously to provide improved predictive maintenance, while both live and historic data can be supplied over the Virtual CISS app or the cloud.

The compact, IP54-rated device offers an operating temperature range of -20 to +80 degrees C, making it suitable for Industry 4.0 applications, including preventative maintenance, industrial retrofitting, digital twinning, and condition monitoring.

Single-chip motor drivers simplify flexible control logic

Tue, Aug 28, 2018

Low-to-mid-power motor controls in the seven to 45V range, can be simplified with the STSPIN830 and STSPIN840 single-chip drivers, claims STMicroelectronics. The drivers contain flexible control logic and low-RDS_(ON) power switches for industrial applications, medical technology, and home appliances.

The STSPIN830 is designed for driving three-phase brushless DC motors and has a mode-setting pin that lets users control the three half bridges of the integrated power stage with direct U, V, and W pulse-width modulated (PWM) inputs, or by applying signals to each gate individually for higher control flexibility. A dedicated sense pin for each inverter leg simplifies setting up three-shunt or single-shunt current sensing for field-oriented control (FOC).

The STSPIN840 can drive two brushed DC motors or one larger motor leveraging ST’s paralleling concept, which allows the integrated full bridges to be configured as two separate bridges or as a single bridge using the two sets of MOSFETs in parallel for lower RDS_(ON) and higher current rating.

Both drivers contain rich features, including PWM current-control circuitry with adjustable off-time, a convenient standby pin for power saving, and protection circuitry including non-dissipative overcurrent protection, short-circuit protection, under-voltage lockout, thermal shutdown, and interlocking to help create robust and reliable drives.

The integrated power stage of each device features ST-proprietary MOSFETs with low RDS_(ON) of only 500 milliOhm to combine high efficiency with economy. The option to use the output bridges individually or connected in parallel, in the STSPIN840, helps trim the bill of materials for multi-motor applications.

According to ST, the integrated, flexible drivers enable more compact and cost-effective controls for industrial, robotic, medical, building-automation, and office-equipment applications. The STSPIN830 is suitable for factory-automation end-points, home appliances, small pumps, and fans for computer or general-purpose cooling. The STSPIN840 is for use in ATM and money-handling machines, multi-axis stage-lighting mechanisms, thermal printers, textile or sewing machines, and vending machines.

The STSPIN830 and STSPIN840 are both in production now, as 4.0 x 4.0mm QFN devices.

Two STM32 Nucleo expansion boards are also available from ST for product evaluation and to build functional prototypes using the STM32 Open Development Environment. The X-NUCLEO-IHM16M1 is for the STSPIN830 and the X-NUCLEO-IHM15A1 is for the STSPIN840 driver.
