About the ConnectCore® 8X

The ConnectCore 8X delivers a secure and extremely cost-effective connected System-on-Module

platform that is slightly bigger than a postage stamp. Its innovative Digi SMTplus™ (patent-pending)

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.MX 8X 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 4.2 dual mode connectivity.
