About the ConnectCore 6

The ConnectCore 6 is an ultra-compact and integrated system-on-module solution based on the NXP

i.MX6 Cortex-A9 processor family.

With processor speeds up to 1.2 GHz and fully interchangeable single-/dual-/quad-core variants, the

ConnectCore 6 offers a truly future-proof platform solution with scalable performance and pre-

certified wireless 802.11a/b/g/n and Bluetooth 4.0, including Bluetooth Low Energy connectivity.

Cloud Connector integration, as part of the Digi Linux and Android software platform support, offers

secure remote management and web services capabilities through Digi Remote Manager. Digi also

offers custom Remote Manager hardware and wireless design services as well as end-to-end

solutions for cloud integration and app development.

About the ConnectCore 6 Power supply architecture

ConnectCore® for i.MX6 Hardware Reference Manual 9

Power supply architecture

The ConnectCore 6 provides a primary 5 V power supply input. This supply is the main power domain

to the on-module Dialog DA9063 power management IC (PMIC), which generates all required supply

voltages for the module components as well as the carrier board.

About the ConnectCore 6 Power supply architecture

ConnectCore® for i.MX6 Hardware Reference Manual 10

The module provides support for a backup battery (coin-cell or super cap) powering the real-time

clock (RTC) on the module. In addition, rechargeable backup batteries (ML414, others) are also

supported.

The PMIC generates the following power domains that are available on the module pads:

n3.3 V (VGEN_3V3)

nMoreover, 5x PMIC LDO outputs are also available on the module pads:

lVLDO3

lVLDO4

lVLDO6

lVLDO7

lVLDO8
