The Digi ConnectCore® 8M Nano from Digi International is based on the NXP® i.MX 8M Nano processor and features up to 4x power-efficient Arm® Cortex®-A53 cores and 1x Cortex-M7 core. This development platform is designed to meet the advanced connectivity and multimedia needs of a wide range of industrial, medical, agricultural, and transportation Internet of Things (IoT) applications.
The Digi International Digi ConnectCore 8M Nano development platform is a highly integrated, cost-effective SOM platform that optimizes power consumption while maintaining a standard of high-performance. This platform is suitable for a vast range of industrial and medical applications including IoT, human machine interactions (HMI), equipment monitoring, audio/voice, edge computing and machine learning.
Designers can lower development costs and go to market faster by leveraging the Digi ConnectCore 8M Nano platform’s pre-certified wireless connectivity, integrated device security framework, remote management, cloud integration, and complete Linux software platform based on Yocto Project™.
Enhance Design Functionality and Reduce Development Time
The DigiConnectCore 8M Nano system-on-module (SOM) is part of a family of SOMs that are designed to speed up development time while increasing functionality to the end product. All Digi ConnectCore SOMs are constructed with a built-in security framework, a range of software enhancements and pre-certified connectivity. In turn, these enhancements support more stable and predictable product development and maintenance costs.
What to Consider in an SOM Partner
All Digi ConnectCore SOMs and single-board computers, including the 8M Nano, come with Digi Embedded Yocto (DEY). DEY is an open-source, production-ready Yocto Project based embedded Linux distribution with fully tested and maintained BSPs and APIX software extensions for security, power management, and wireless connectivity. As a distribution, DEY provides the following:
- • Digi BSP - DEY provides precompiled images that are ready to use, but you can also compile the whole distribution from source. The distribution contains the following components, which have been customized and tested for the ConnectCore module.
- • A U-Boot - based bootloader customized for the ConnectCore module to booth the Linux image. You can configure U-Boot at boot time, and it integrates a useful set of commands so you can program your own scripts. Digi provides source code that can be tailored to your design requirements as well as integrated within the build system. When the Yocto image is built, the U-Boot image is built with it.
- • A Linux kernel customized for ConnectCore products. DEY includes the kernel source as well as device tree configuration files.
- • Reference root file system images using the DEY reference distribution. The DEY distribution makes the following choices:
- • The default selection of packages through the supported images
- • Systems as initialization manager
- • Framebuffer and XWayland support
- • Bluez5 support
- • QT5 support
- • Pre-compiled framebuffer images (dey-image-qt-fb) or XWayland images (dey-image-qt-xwayland)
- • Multimedia enabled (using the gstreamer open source framework)
- • Standard Linux networking tools NetworkManager and ModemManage
You can further customize it by creating your own DEY-based distribution.
- • SDK - DEY includes a precompiled C/C++ toolchain. You can use it to cross-compile applications to run on Digi embedded platforms.
- • Precompiled images - DEY includes pre-built reference images to accelerate your development process.
- • Documentation - DEY comes with comprehensive documentation covering all the development and technical aspects of the ConnectCore products.
- • Software extensions - DEY is designed to improve your time to market with common and simple to use software features that work out of the box.
Think About Security Up Front
As the IoT development grows, it’s critical to make security a top priority for every application, especially if an application transmits sensitive data.
Digi TrustFence® is the security framework for Digi ConnectCore solutions. Digi TrustFence is an integrated, tested, and complete Linux device security framework that simplifies building secure connected products. Designed for the long product lifecycles of embedded devices, Digi TrustFrence allows designers to easily integrate device security, device identity, and data privacy capabilities.
The built-in security from Digi TrustFence offers immediate access to critical features including secure connections, authenticated boot, encrypted data storage, access-controlled ports, secure software updates, and seamless integration of the dedicated on-module Secure Element.
The full range of Digi TrustFence’s built-in features include:
- • Secure Boot: Ensures only signed software images can run on a device.
- • Encrypted Storage: Local file system encryption keeps internal device data safe.
- • Protected Ports: Access-controlled internal and external ports prevent unwanted “back doors”.
- • Device Identity: Root of trust, certificate management, and secure key storage identity protection.
- • Secure Connection: Enterprise-level data encryption for wired and wireless network privacy.
- • Lifecycle Longevity: Rely on Digi-maintained future-proof platform architecture.
Design for Future Scalability with the 8M Nano SOM Platform
As the speed to market increases, designers have less time to make critical decisions. The Digi ConnectCore family of SOMs are designed with longevity in mind to meet the future requirements of products with a 10+ year lifespan. Digi ConnectCore provides functional scalability from the single-core i.MX 6UL to dual/quad-core versions of the 8M Nano SOM and 8X SOM. In addition to various processor core options, Digi ConnectCore includes upgradable memory up to 16 GB eMMC flash and up to 2 GB LPDDR4 to meet a range of deployment options. This provides the ability to scale with increased processor cores and memory to future-proof your designs.
Additional Built-In Benefits
Digi International’s “hardware enabled, software defined” strategy offers the ability to streamline your product development process, maintain products over the long-term and redeploy existing applications to new business cases. All Digi ConnectCore SOMs come with an integrated pre-certified dual-band WiFi 802.11 ac and Bluetooth 5, as well as enterprise WiFi capabilities not typically supported by other SOMs.
