About the ConnectCore® 6UL
The ConnectCore 6UL is a secure and extremely cost-effective connected System-on-Module platform.
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.MX6UL application processor, the module is the intelligent communication engine
for today’s secure connected devices. It integrates dual-Ethernet and pre-certified dual-band Wi-Fi
(802.11a/b/g/n/ac) with dual mode Bluetooth 4.2 connectivity.
