How to Buy

The network-enabled Digi ConnectCore for i.MX53 is a highly integrated and future-proof system-on-module (SoM) solution based on the new NXP/Freescale i.MX53 application processor with a high performance 1 GHz ARM Cortex-A8 core, wired and wireless connectivity, powerful 1080p/720p video encoding/decoding capabilities, dual-CAN bus interface and a complete set of peripherals.

The Digi ConnectCore for i.MX53 family builds on the successful ConnectCore for i.MX51 modules by providing a form factor compatible option with significantly improved processing, memory, video and connectivity capabilities. It is a scalable and energy-efficient module family that is ideal for medical devices, security/surveillance equipment, industrial applications, kiosk systems and digital signage integration.

The ConnectCore for i.MX53 modules combine industry-leading performance, low power consumption and easy design integration with key features like integrated power management IC, on-chip multimedia support, including multi-format 1080p video hardware decoding, 2D/3D graphics acceleration, dual display/camera interface, hardware encryption engine, 802.11abgn Wi-Fi interface (150 Mbps), Bluetooth 4.0 with HDP support, dual 10/100 Ethernet option, dual-CAN bus, SATA II storage interface and a comprehensive set of additional peripherals.

Modules in the ConnectCore i.MX family feature the design, development and administrative advantages offered by Digi Remote Manager. This robust cloud platform makes it easy to configure and manage deployments and integrate devices with virtually any application. Device manufacturers can build secure, highly scalable and cost-effective solutions that seamlessly tie assets to applications, regardless of location.

Complete and cost-efficient Digi JumpStart Kits® for Digi Embedded Linux, Android and Microsoft Windows Embedded Compact 7 allow immediate and professional embedded product development with dramatically reduced design risk and time-to-market. Additional support for Yocto Embedded Linux is also available for download.
