STM32WB High-performance SoC specifications
STM32WB High-performance SoC specifications

The Cortex-M4 combined with a Cortex-M0+ for network processing makes sure the STM32WB to be the latest ultra-low-power microcontroller to combine superior RF performance with longer battery life. The SoC also combines essential circuitry for connecting to the antenna. It also packs right amount user and system memory, hardware encryption, and customer-key storage for brand and IP protection.

These days, only a few manufacturers offer similar dual-processor wireless chips capable of managing the user application and the radio separately for maximum performance. Alternative chips typically utilize entry-level ARM Cortex-M industry-standard cores, which introduce technical limitations and very low amount of onboard flash memory.

The robust and low-power 2.4GHz radio consumes only 5.5mA in transmit mode of this new STM32WB and as little as 3.8mA when receiving. This device also include STM32 digital and analog peripherals that are engineered for low power consumption and complex functionalities, including timers, ultra-low-power comparators, 12/16-bit SAR ADC, a capacitive touch controller, LCD controller, and industry-standard connectivity including crystal-less USB 2.0 FS, I2C, SPI, SAI audio interface, and a Quad-SPI supporting execution in place.

STM32WB devices will be available in an array of 48-pin UQFN, 68-pin VQFN, or 100-pin WLCSP with up to 72 general-purpose I/Os (GPIO). Each can be specified with any of three memory configurations, giving a choice of 256KB Flash and 128KB RAM, 512KB-Flash/256KB-RAM, or 1MB-Flash/256KB-RAM.

SODAQ Cellular IoT Development Kit Supports LTE-M, NB-IoT, GNSS and Arduino

SODAQ wants to provide you with the tools to build for the estimated 25 billion Internet of Things by 2020 using their set of Cellular IoT suite called SODAQ SARA Family.

SODAQ SARA Board

Several industriy analysts have claimed that we will have 100 billion IoT devices connected and in circulation by 2050, with the majority of them running on the cellular network mostly due to its large-scale access and ease of deployment. We have already seen IoT deployments on 2G networks but the recent movement of Telecom operators into 4G networks and outfacing their 2G networks are paving ways for new IoT focused technologies to be integrated into the 4G networks. Some of these technologies being developed and deployed are the LTE-M and NB-IoT (Narrow Band IoT). NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and enabling a large number of connected devices. LTE-M will allow Internet of Things devices to connect directly to a 4G network, without a gateway, and on batteries.

To facilitate the development of these exciting technologies, SODAQ which previously launched their NB-IoT shield for Arduino last year is incorporating a range of u-blox SARA modules in its design. The SARA modules are available for NB-IoT, LTE-M but also for 2G and 3G. The following are the u-blox Sara modules used in their IoT cellular suite are:

  • SARA-N211 – NB-IoT, band 8 and 20, for the European and African market.
  • SARA-R410M – Dual mode LTE-M and NB-IoT module for all global bands.
  • SARA-R412M – Triple mode module with LTE-M, NB-IoT, and 2G for all global bands.

The SODAQ board is called the SODAQ SARA. The SARA is an Arduino sized and compatible development board running the Atmel SAM-D21 32 bit microcontroller, along with one of the three u-box modules. In addition to the cellular modules, the SODAQ SARA comes integrated with a u-blox SAM-M8Q GNSS module for precise geolocation. SODAQ claims the GNSS module offers more accurate positioning than conventional GPS because it utilizes the Beidou, Galileo and Glonass satellites. It also comes with an accelerometer/magnetometer chip.

SODAQ SFF Edition

SODAQ is also launching a small form factor (SFF) edition of the same board with a size of about 55 x 25mm and still maintains the same functionality on the bigger board. One significant feature of their boards is that you can power the board directly with a solar panel and further program the boards with the Arduino development tools (Arduino IDE).

SODAQ is currently crowdfunding the boards on Kickstarter. With the three different LTE IoT module and two types of boards, SODAQ is offering a total of 6 different versions of its boards:

  • SARA-N211 NB-IoT (Band 8/20) for 90 Euros
  • SARA-R410M NB-IoT  + LTE Cat M for 100 Euros
  • SARA-R412M NB-IoT + LTE Cat M + 2G fallback for 110 Euros with 1,200 mAh battery
  • SFF N211 for 95 Euros
  • SFF R410M for 105 Euros
  • SFF R412M for 115 Euros with 800 mAh battery

If all goes well in the Kickstarter campaign and SODAQ raises the required €25,000 over the remaining days of its campaign, the Internet of Things Development Suite will start shipping out to backers during March 2018.

With the integration of IFTTT, you can easily automate some actions like for examples – if an email is received then send sensor reading or feed the fish for a while, another interesting case is – if a weather forecast states there is a likelihood of rain then closes the cage. Cloudio also provides support for upload program to multi-board at once, a perfect option if you will be managing a large number of boards.
Cloudio and Raspberry Pi
At the heart of the Cloudio board is the Atmel 8-bit AVR Atmega32U4 controller and comes in a portable size that makes it compatible with Raspberry Pi 1/2/3/Zero and ZeroW. It comes with a 0.96″ OLED Screen, a display that can be used for displaying real-time sensor values, custom messages and even supports emojis. The board includes proximity, light and temperature sensors and an extra 3 ADX ports for interfacing with external sensors. The board consists of a proximity, light, and temperature sensors plus 3x ADC interfaces for connecting other sensors such as humidity and motion. With the Cloudio, you will never run out of 5V ports as it comes with three digital 5V output ports. Cloudio does not require any external power supply unit and gets its power from the underlying Raspberry Pi. Other features of the board are a mini 5V servo motor port, a buzzer, RGB LED and tactile switch.
According to Steve Carr, the Global Head of Marketing at Premier Farnell and Farnell element14, he says –
“The versatility of GraspIO Cloudio along with its ease of use will make it popular with makers and innovators in a wide range of application environments. Cloudio, when combined with a Raspberry Pi, is a Full Stack IoT platform meaning that you can programme IoT devices simply and quickly with drag and drop programming on a mobile app. The combination of built-in hardware facilities and access to innovative application software will make Cloudio a valuable addition to the range of tools available to developers of projects involving voice, motion, imaging and cloud interaction.”

SocioNext MN87900 is a Single-Chip 24 GHz Radio Wave Sensor for the Internet of Things

The Socionext MN87900 from Socionext is a powerful and low-power single-chip microwave sensor at 24GHz with sophisticated sensing capabilities like motion detection, speed and direction detection and so many, that can quickly find applications in the Internet of Things sensing applications.

Socionext MN87900

Unlike PIR sensors like the popular HR-SR501 that can detect motion to about 3 meters at about 120 angles and based on the concept of detecting infrared energy emitted by an object while attempting to determine if it’s a motion or not, the Socionext MN87900 is a microwave sensor that sends out microwave signals and detects the bounce back signals to decide if it’s a motion or not. Microwave sensor uses what we call the Doppler’s Effect concept.

SocioNext MN87900 is a 24 GHz and very tiny, measures about 12mm x 7mm x 1mm making it ideal for the small size requirement in the most Internet of Things application and other applications in the areas of smart-home, automotive or driver assistance systems, medical applications, and many more. Based on a single-chip radio frequency IC (RFIC) that offers a multi-mode sensing capability for detecting stationary or moving objects and measuring the distance and direction of movement, including whether an object is approaching or leaving. This multi-mode sensor capability gives the device ability to re-adapt its functionality to different case scenario without making any single hardware changes.

The RFIC can be used to sense very slow movements (like breathing and heartbeats), and even detect the movement of multiple objects within a 160-degree radius to a distance of about 8 meters away. With slight modification, the RFIC can reach a range of up to 30 meters.

Apart from having powerful sensing capabilities, it is also power friendly. During continuous operation, the sensor can take up to 500mW, but this can be reduced to an intermittent operation where for example, during a one-sixth burst, the sensor can take about 80mW, a very drastic reduction in power. The MN87900 can pass through fabric or resin like materials, and unlike camera-based people detecting applications, the MN87900 doesn’t need to capture or display images to identify people or objects which is handy for privacy-concerned applications.

The MN87900 supports SPI as a form of interface to microcontroller system. Along with the hardware, a simple API system was developed to support the designs of CW, FSKCW, and FMCW mode capabilities to provide distance, direction, and relative velocity.

The following are the SocioNext MN87900 key specifications:

  • Sensing Modes – CW, FSKCW, FMCW (moving or stationary)
  • Detection
    • Motion direction – approaching or leaving
    • Motion speed – up to 200 km/h
    • Range – 0.15 to 8 meters 80°@-3dB, expandable to 30 meters
  • Variable frequency width –  24.15±0.1 GHz
  • Host Interface – SPI
  • High sensitivity – -110dBm
  • Transmission Power: 0.8mW
  • Fast frequency pull-in: 100 µs
  • Automatic adjustment: Built-in initial adjustment function (e.g. adjustment of RC filtering)
  • Power supply voltage: 2.5V
  • Current consumption: 200mA
  • Module size: 12mm x 7mm x 1mm
  • Weight – 145 mg
  • Temperature Range – -40°C to 85°C

The module pricing is currently not available, and more information about the product can be found here.

Bosch BMA400 – Did you thought accelerometers couldn’t get any better?

Accelerometers are used in almost all fields, and they have been growing in popularity in IoT and wearables. Nowadays, those devices require a of energy, and because of this, they need to be constantly charged or batteries need to be constantly changed which causes users to lose interest, or to be limited by this problem. Size might be a problem too because some MEMs (micromechanical systems) acceleration sensors are too big to be implemented in everyday portable objects. In June 2018, Bosch will unveil their BMA400, a sensor that extends battery life and has a huge range of capabilities in a small size.

BMA400 is capable of measuring tilt, orientation, tap/double tap, and step counting (with activity recognition) using a low- noise measurement of accelerations in three perpendicular axes. Additionally, the device only uses 10% of the energy current comparable devices use which makes it useful for applications where charging is impossible. For example, this device could be used for package tracking over long distances, saving power by putting itself on sleep mode until something happens (the package is mishandled) which could compromise the quality of the product inside the package.

Other applications include home automation (automatic air conditioning that considers status (open or closed) of windows and doors), security (burglar detection), and sports. The BMA400 includes an activity detection function that can differentiate between walking, running, and standing. All this could be applied into wearables, and because of its size it could be a game changer in hybrid smartwatches (traditional watch with added smarts in a discrete way).

BMA400 measure only 2 mm x 2 mm x 0.95 mm, and device data can be retrieved over longer intervals (FIFO buffer of 1kB). Other specifications include:

  • 12-bit digital resolution
  • Output data rate (ODR) of 12.5 Hz to 800 Hz
  • Supply voltage of 1.71 V up to 3.6 V

Complete list of specifications can be found in the official website.

This improvements in an already widely used technology could result in advances in thousands of different devices, and in the implementation of this sensor in devices where it couldn’t be fitted before. Improving battery means improving product usability which results in happy users who can now use their device for longer periods of time. Also, makers and hobbyists could now apply this technology to new devices using the increased battery life as an advantage.

HoneyWell´s Small, High Performance Pressure Sensor

Honeywell is a technology company working towards connecting the world. They are currently working on connected homes, buildings, plants (such as refineries), warehouse, workers, aircrafts, vehicles, and healthcare while addressing challenges such as energy, safety, security, productivity, and global urbanization. To enhance product performance, Honeywell has designed a MicroPreassure board mount pressure sensor measuring only 5 mm x 5 mm.

Nowadays, the market is filled with low performance cheap sensors or high performance expensive sensors which do not meet the need for fully functional cheap sensors for industrial and medical applications. Honeywell’s MPR is a small piezo resistive silicon pressure sensor with digital output, and it is the smallest ported pressure sensor in the market. This device was designed to be easily installed and to work without the need for external amplification. MPR MicroPreassure sensor has amplification, compensation, and low power consumption. Additionally, the device has high accuracy, it is liquid tolerant, meets moisture sensitivity level 1 requirements, and it is durable (it has strong metal ports).

This device could not only help improve already existing technologies, but also it would allow for this type of sensors to be introduced in new objects such as wearables, or common objects for IoT applications. In medical industry the sensor can help reduce the size of bulky devices and may even allow the patients to own their own monitoring device at home. MicroPreassure was specifically developed for high volume applications such as appliances, non-invasive blood pressure machines etc. For circuit designers and engineers, this sensor gives the opportunity to reduce the size in all the devices by using less space in boards and PCBs.

It was designed to meet high volume requirements (250,000 units/year), so with a low production cost and a really good performance, designers can now include these sensors to reduce their device price and to give them optimal performance. The user will have access to 1.5% accuracy and 13 bits of effective resolution which makes the processes more efficient. As a result, depending on the design, the device may be less prone to errors, require less power, or make less noise.
