Core Module naming information
The idea is to put more Core Module specific technical information into the product name. New Core Module names
will have following technical information covered in their names.
•
Product Family,
•

Operating Temperature Range,
•
Crystal Frequency [MHz],
•

That expands of course the name but allows the customer to get the most important Core Module specific
information at the first sight. Have a look at the example below to get an idea of the new Core Module names.

4 Extension Connectors
The Extension Connectors enables the connection of additional hardware(e.g. Extender boards) to the SBC-i.MX51.
Bluetechnix offers additional hardware for the SBC-i.MX51 such as a display, communication and experimental
extender board. See our website for more information. (http://www.bluetechnix.com/goto/ext-sbc-i.mx51-ov)
All connector I/O pins are either connected to the i.MX or to the MC13892 (see pin description). Most of the pins
connected to the i.MX have alternate functions; for more details see the Pin Description Tables and consult the
i.MX51 datasheet.
The connectors for the GPIO- and Video Extension Connectors are FX10A-80P/8-SV1(71) from Hirose (mating part is
FX10A-80S/8-SV(71)). All other connectors are standard 2.54mm-pitch headers.

Digital Video Connector (X11)
The Video Extension Connector is designed to add a custom video extension board with user-defined camera and
display components, e.g. a CMOS sensor and a LCD display.

Additionally, some GPIOs are available for configuring the interface and handshaking. Touch screen functionality
can be implemented by connecting four analog lines, which are routed to the MC13892, to an appropriate display.

The Video Extension Connector provides six different supply voltages. They can be used for a custom extension
board. Some supply voltages are generated by the MC13892 and can be set to different values. They must be set
and enabled first, by configuring the companion IC. The following table shows the maximum supply current for
each voltage.

It is not advisable to alter these voltages; otherwise the board may get damaged.
The P_SWLED voltage drives the LEDs connected to the LED-Driver Pins. The output voltage will be set
automatically by the MC13892. For LED connectivity, see Figure 4-3. Please also refer to the MC13892 errata sheet
available from the Freescale website.

Be aware that this power supply is available on both extension connectors and this is the maximum current that
can be drawn altogether.

Battery Operation
The SBC-i.MX51 is not designed for battery operation. Anyhow there is a possibility to connect a Li-Ion or LiPobattery to the Board, with some small board modifications. If you want to do this, please contact Bluetechnix for
support.
5.7
Backup Battery
There is also a possibility to add a 6.8mm rechargeable or non-rechargeable lithium coin cell to keep the RTC
running and the RAM self-refreshing. The SBC is delivered only with a 6.8mm coin cell holder but without battery.

9 Dependability
9.1
MTBF
Please keep in mind that a part stress analysis would be the only way to obtain significant failure rate results,
because MTBF numbers just represent a statistical approximation of how long a set of devices should last before
failure. Nevertheless, we can calculate an MTBF of the SBC-i.MX51 using the bill of material. We take all the
components into account. The PCB and solder connections are excluded from this estimation. For test conditions
we assume an ambient temperature of 30°C of all SBC-i.MX51 components except the i.MX® processor (80°C) and
the memories (70°C). We use the MTBF Calculator from ALD (http://www.aldservice.com/) and use the reliability
prediction MIL-217F2 Part Stress standard. Please get in touch with Bluetechnix ([email protected]) if you are
interested in the MTBF result.

Description
I2C-1 pullups could be overdimensioned. In such cases, certain voltage might not
be available since the i.MX51 cannot communicate with the power management
IC (MC13892). A fix for this issue is provided by replacing two resistors (currently
populated: 4k7, new value: 1k5). This will be fixed starting with revision 2.2 and all
devices delivered after 2011/08/22.
https://support.bluetechnix.at/wiki/Known_Issues_(SBC-i.MX51)
It is recommended to take care of active cooling when multiple USB devices are
attached, HDMI is active and you are using supply voltages above 16VDC.
The USB hub is working in bus powered mode. For information on how to use self
powered mode please see:
https://support.bluetechnix.at/wiki/Known_Issues_(SBC-i.MX51)
Using the USB OTG in device mode applies 5 volts on the USB port (Pin x) which
doesn’t comply with the USB-OTG standard. It may lead to small equalizing
currents.
