The Digi ConnectCore® 6UL module delivers a secure and extremely cost-effective connected System-on-Module platform that is slightly bigger than a postage stamp. Its patent-pending Digi SMTplus™ surface mount form factor allows you to choose simplified design integration leveraging proven and easy-to-use edge-castellated SMT technology, or a versatile LGA option for ultimate design flexibility with access to virtually all interfaces.

Built on the NXP i.MX6UL UltraLite application processor, the module is the intelligent communication engine for today’s secure connected devices. It seamlessly integrates dual-Ethernet and pre-certified dual-band Wi-Fi (802.11a/b/g/n/ac) with Bluetooth 5 connectivity.

Embedded device security is a critical design aspect for the growing number of connected applications (“IoT”) and the ConnectCore 6UL removes the implementation barriers by providing you with Digi TrustFence, a fully integrated secure module platform with complete Linux software support.

* Patent-Pending

** DIGI ConnectCore 6UL products have the cryptographic functions implemented only within the following: Digi TrustFence® Embedded Security Framework (cryptographic algorithms are implemented within Linux OS v. 4.1.38), Wi-Fi module (802.11a/b/g/n/ac) and Bluetooth 4.2 module. Cryptographic and other functions and abilities of Digi TrustFence® Embedded Security Framework are accelerated by embedded NXP i.MX6UL processor. The processor itself is not used as a separate cryptographic module and does not accomplish any cryptographic functions by itself.
