Toradex i.MX 8X-based System on Modules gain AWS certification and support for Torizon embedded Linux

Toradex is now bringing Torizon, its easy-to-use industrial Linux software platform, to its System on Modules (SoMs) based on the i.MX 8X applications processors from NXP®. Toradex offers the i.MX 8X-based SoMs in two form factors: the small Colibri iMX8X and the powerful Apalis iMX8X, with optional ECC memory. Toradex was among the first few partners to be part of NXP’s Early Access Program for the i.MX 8X applications processors and was shipping early samples of the Colibri iMX8X in 2018.

Additionally, the Colibri iMX8X is now AWS-certified and available in the AWS Device Catalog, based on certification requirements for Amazon IoT Greengrass. This certification is part of the AWS Device Qualification Program.

i.MX 8X-based SoMs are ideal for demanding applications requiring the highest reliability and power-efficient processing. Advanced security and safety features make these SoMs safety-certifiable. The SoMs come with up to four 64-bit Armv8 Cortex-A35 cores. Compared to the Cortex-A7, the Cortex-A35 can deliver up to 40% faster performance — and at the same clock speed — while consuming 10% less power. Compared to the Cortex-A53, it uses up to 32% less power at the same clock speed.

The Vivante GPU supports OpenGL™ ES, OpenCL™ and Vulkan® for modern graphics, or to accelerate such computing tasks as deep learning inference. The SoMs are also available with onboard Wi-Fi and Bluetooth, supporting dual-band 802.11ac 2×2 MU-MIMO Wi-Fi and Bluetooth 5.

An advanced, 28-nanometer FDSOI silicon process was chosen to build the SoC to increase MTBF and decrease soft error rates, which is crucial for critical applications. The additional Cortex-M4 core permits the offloading of critical real-time or safety tasks from the main operating system.

Toradex now provides Torizon, an open-source, embedded, industrial Linux platform for these i.MX 8X-based SoMs. Torizon provides a modern development platform, allowing developers to focus on their applications instead of on building a Linux operating system. Torizon offers integration with Visual Studio and Visual Studio Code. It comes with an automotive-grade update client for simple and secure over-the-air updates. Toradex’s high-quality reference images for the Yocto Project are also available for free. In addition, Android and QNX are available via the Toradex Partner network for i.MX 8X-based SoMs.

With the AWS certification for the Colibri iMX8X, developing cloud-connected devices that use Amazon IoT Greengrass and other AWS offerings is now simpler.

The Colibri iMX8X is pin-compatible with the complete Colibri family, including SoMs based on the NXP® i.MX 6i.MX 7i.MX 6ULL and NVIDIA® Tegra SoCs. Similarly, the Apalis iMX8X is compatible with SoMs featuring the i.MX 8QuadMaxi.MX 6 and NVIDIA TK1 SoCs.

Toradex’s Colibri and Apalis SoMs are an ideal fit in applications such as healthcare, transportation, industrial automation, testing and measurement, and smart cities.

TransferFi Launches Wireless Power Network for Lightning Up Sensors Up To 55 Meters Away

For a while now, we have witnessed the use of wireless charging, by placing a phone or other devices that support wireless charging on a charging pad. Energous is one of the companies that started promoting their near-field, mid-field, and far-field wireless charging solutions, with far-field meaning within a room. But so far, they only have released near-field devkits and products. However, Singapore based TransferFi Pte has developed its own wireless charging solution called the TranferFi wireless power network (TFi WPN), aimed at powering sensors up to 55 meters away, and specifically aimed at building and factory automation to enable companies to save on installation and cabling costs.

The TFi WPN functions with a gateway powering up and receiving data from sensors wirelessly, having a range of up to 55 meters.  The TFi Gateway Max Turin-1 has a range of up to 32 TFi Sense devices through multichannel beamforming, offering support for up to 16 channels and can be connected to Modbus, BACnet & Web services. TFi Sense Turin-1’s sensor node is powered by a secret Arm Cortex-M4 microcontroller, and it enables a 3-axis accelerometer, a microphone, temperature, pressure, humidity & TVOC (Total Volatile Organic Compounds) sensors. It also further equipped with proprietary encryption & AES-128, and transmit at up to 5 Hz.

The TFi Sense Turin-1 is optimized to perform within the 860MHz – 940MHz frequency ranges. However, TransferFi can also offer the solution in the 2.4GHz – 5.8GHz bands on request. A representative of TransferFi Pte explains:

“All this is done through patented signal optimization and beamforming algorithms enhanced for long-range of Wireless Power Transfer (WPT) to more than 100m. We’re working on a developer kit which has loads of customization features for different sensors, communication ports, antenna and micro controllers.”

The company did not disclose more information about the kit at this time, but it is likely the “Max” gateway is relatively pricey, probably because the development kit will include TFi Gateway Lite Turin-1 instead which would just support one sensor nodes and have a shorter range.


The sensor is set to be a programmable sensor with control abilities for Home IoT or project. Comparing the TransferFi to Energous, the company says:

“The main difference with Energous is that we are truly long distance with transmission over 24-55m. Focus is on industrial Iot, enabling a digitization of a physical space.”

One of the key advantage of the solution is its much lower installation cost, due to the fact that traditional wired sensor deployments waste 80% of the time on installation & cabling, which is more than 60% of the overall sensor deployment budget. The TFi WPN platform boasts of reducing deployment time by 80%, and cabling and installation cost by 50%.

iWave i.MX8M Mini Board with NXP eIQ ML Software Enables Low Cost Facial Recognition System

Have you recently been sceptical of using a contact-based access system in your office or a public place? This trait is a major concern in most places for a valid reason. An access surface in a public place is used by many individuals, which makes it a potential source for contracting the deadly Covid 19 virus. Taking this into account, iWave Systems, a leading embedded solutions provider, has successfully demonstrated an alternative solution using facial recognition technology. The solution helps customers with a zero-contact access application by using individuals’ faces to authorize access to a commercial/industrial space, home/office, transportation, banking, and Government sites.

Facial Recognition:

Facial Recognition is the process of recognizing the identity of a person by using their facial features against a previously stored database.

It is a technology that uniquely identifies or verifies a person by comparing and analysing patterns based on the person’s facial details. The face capture process transforms the analogy information into a set of digital information, while the face match process verifies the information with a database of known faces to find a match.

iWave Solution :

The facial recognition demo is running on iWave’s development board based on the NXP® i.MX8M Mini applications processor. The power-efficient edge computing platform with a SODIMM form factor is coupled with a MIPI Camera module (1080p@30 fps) , MIPI Display (1920 x1080 60fps), and multiple connectivity options. Through the support of key features such as camera, display, connectivity, and the NXP eIQ machine learning software, the i.MX 8M Mini board provides an intelligent platform for the development of facial recognition systems.

Demo Environment

The captured image and stored images are fed to the application to recognize the faces. eIQ OpenCV ML software compares the novel face features with the known face images in the Django framework database. Real-time data logging can be configured to send the information with alert for authorized or unauthorized detection.

NXP eIQ OpenCV Machine Learning Software:

 iWave i.MX8M Mini board is integrated with the NXP eIQ OpenCV machine learning softwarewhich enables faster time to market while reducing the development complexity. The eIQ software includes pre-optimized libraries and tools to perform machine learning and computer vision applications. The eIQ software enables developers to accelerate the development flow of the ML applications by taking full advantage of the underlying i.MX8M Mini SoC. The software supports C++/Python/Java API’s which provides the programming flexibility to the developers.
