Maximum data rate: 400Mbit/s (in 4 bit Mode)
The microSD card must be inserted with the contacts facing the heat sink.
MicroSD cards available in consumer electronics stores are generally not designed or
suitable for industrial applications. A lifetime in terms of write/erase cycles is often not
specified for these cards and is in the range of a few hundred cycles.
When purchasing microSD cards, make sure that the card is suitable for the application and
environmental conditions.
Unexpected data loss or device failure can result when using unsuitable microSD cards.
Kontron recommends microSD cards from swissbit®.
eMMC
The bootable eMMC (JEDEC 5.0) built into the Control Unit serves as operating system and program memory.
Depending on the version and geographical region, the storage capacity is 4GB, 8GB, 16GB, 32GB, 64GB or 128GB.
Status LEDs
There are two status LEDs next to the X1 Power connector.
Table 5: Status LEDs

G2/S5 (see chapter 3.1.8)
S1 Blue Connected to GPIO of the processor. Can be controlled by user software. In
delivery state without function (always on).
Power Management and Power Button
The Power Button is located below the power connector X1 next to the PWR status LED.
The Control Unit supports the following power states of the Intel processor:
Table 6: Power Management Energy States (ACPI)
G/S State Description
G0/S0 FULL ON CPU is running. Peripherals can be individually set to power save
mode.
G1/S3 Suspend-to-RAM (STR)
Standby-Modus Most of the hardware is switched off, the operating status is
stored in the volatile memory (RAM). The system can be woken up.
G1/S4 Suspend-to-Disk (STD)
Idle state The operating state is stored in non-volatile memory (boot
medium). The system can be woken up.
G2/S5 Soft-Off System is switched off (except RTC), but the supply voltage is
present, therefore the system can be reactivated via the Power
Button.
