ConnectCore 6 SBC features and functionality
ConnectCore 6 Hardware Reference Manual 2
ConnectCore 6 SBC overview
The ConnectCore 6 SBC is a Pico-ITX board featuring the Digi ConnectCore 6 module that
integrates a Freescale i.MX6 application processor, DDR3 DRAM memory, eMMC memory, WLAN/
Bluetooth module, power management IC for optimized power consumption applications and a
programmable microcontroller assistant for supporting additional interfaces.
The ConnectCore 6 SBC provides a selection of I/O interfaces including two USB 2.0 ports, one
micro USB OTG connector, micro SD card slot, HDMI, audio jack for stereo audio output and a
Gigabit Ethernet port. All these connectors together with the main power connector are located
on the front edge of the board making them easily accessible if the board is assembled into an
enclosure.
The rear edge of the ConnectCore 6 SBC provides a great selection of multimedia connectors
including LVDS, MIPI CSI-2 camera, MIPI DSI display, 8-bit parallel camera and 24-bit parallel
display.
Additional on board connectors provide support for SATA interface with power supply, JTAG and
console debug ports, coin cell connector to supply the RTC, and expansion connectors for USB,
second LVDS, second 8-bit camera interface, two CAN ports, I2C, SPI, three UART ports, twelve
GPIOs and audio input and output.
The board provides a mini-PCIe socket for connecting full or half size PCI express mini cards. A
micro-SIM card is connected to the mini PCIe slot making the ConnectCore 6 SBC ready for a mini
PCIe cellular card.
The ConnectCore 6 SBC also has a connector for a Digi XBee module.
The board is powered from a single 5V DC supply. An overvoltage circuit protects the board from
input voltages up to 12V.

ConnectCore 6 SBC DC-In Connector
ConnectCore 6 Hardware Reference Manual 6
ConnectCore 6 SBC Interfaces
ConnectCore 6 SBC DC-In Connector
The ConnectCore 6 SBC has a +5V DC-In power connector (J1) to provide power to the system. A
DC-Jack connector is used to connect the DC-In power supply.
Power LED
A green LED near the power connector shows the status of the power input. This LED is ON when
a valid power supply is present. If the power supply voltage is higher than 5.5V the overvoltage
protection circuit will block the power supply input and the power LED will turn off.
LED Signal Note
POWER VSYS Green LED

ConnectCore 6 SBC DC-In Connector
ConnectCore 6 Hardware Reference Manual 7
Overvoltage protection
An overvoltage protection circuit is implemented on the ConnectCore 6 SBC. If the voltage value
of the DC-In supply signal is higher than 5.5V the supply input is disconnected of the system.
5V regulator
The ConnectCore 6 SBC has several interfaces that need a regulated 5V supply. To generate this
supply one LTC3125 step-up DC/DC converter is used. This DC/DC converter can generate a
regulated 5V from an input supply ranging from 1.8V to 5.5V. The LTC3125 will maintain voltage
regulation even when the input voltage is above the desired output voltage.
The 5V regulator is enabled by the ConnectCore 6 signal PWR_EN (PMIC_GPIO7). On low power
mode this regulator is disabled.
The following table lists the interfaces of the ConnectCore 6 SBC that are sourced from the +5V
supply.
Interface Comments
USBH1_VBUS Power supply for the USB Host controller of the i.MX6 CPU
SATA Supply for the SATA interface
USB OTG Supply for the USB devices connected to the USB OTG
USB Host Supply for the USB devices connected to the USB Host ports
LVDS0 Supply for the LVDS backlight
HDMI Supply for the HDMI display
Parallel display Supply for the parallel display
MIPI display Supply for the MIPI display
MIPI camera Supply for the MIPI camera

SBC coin cell connector
ConnectCore 6 Hardware Reference Manual 8
SBC coin cell connector
The ConnectCore 6 SBC provides a 2-pin, 1.25mm pitch straight connector for connecting an
external coin cell or super capacitor to power the RTC interface when the main supply is off. If
higher voltage is present on the main supply, it will be used as a power source for the RTC.
The following table shows the pinout of the coin cell connector.
There are three types of components that can be connected to this connector: Lithium coin cells
(Primary cell: non-rechargeable), Lithium coin cells (Secondary cell: rechargeable), and Supercaps.
When a Primary Lithium coin cell is connected, the PMIC backup battery charger must be turned
off and this pin is used strictly as an input. It is hazardous to attempt to charge Primary Lithium
cells as they may vent or explode. Secondary Lithium coin cells are only made available directly to
manufacturers of equipment that could use them, in that case they are normally required to
design their product to prevent the user gaining access to this part since there is a danger to the
user if by replacing it, they fit a primary type (the only sort that they are likely to be able to source)
into the charging circuit. When a Secondary Lithium coin cell is used, both the charging current
and the termination voltage are programmable. When a Supercap is used, both the charge
current and termination voltage should be set to the maximum values.
The advantage of using a Primary Lithium coin cell is that the energy density usually allows years
of service since the self discharge rate is low. The advantage of using a Secondary Lithium coin
cell is that the self discharge rate is usually sufficient to allow a few months of support for the
RTC before it will need recharging. The advantage of the Supercap is that it is intrinsically safe and

can out-last the Primary Lithium coin cell option, however the self discharge rate is high meaning
that a 1F capacitor at 25° C is likely to support the RTC for approximately 5 to 10 days.
A programmable constant charge current charger with a programmable top-off charging voltage
is provided for charging of Secondary Lithium-Manganese coin cell batteries and super
capacitors. Charging current is programmable from 100uA to 6mA. Termination voltage is
programmable from +1.1 to +3.1V.
The minimum voltage of the coin cell supply is +2V. The maximum voltage of the coin cell supply
is +3.6V.

Boot mode
ConnectCore 6 SBC provides four resistors to configure the boot mode. These resistors are used
to override the boot mode configuration selected on the ConnectCore 6 module. By default these
four resistors are not populated and the ConnectCore 6 SBC will boot with the default boot mode
selected on the module.
The following table shows the resistors configuration for the different boot modes.
Note A different resistors configuration than the ones listed on the table might prevent the
ConnectCore 6 SBC from booting.
