== Interfaces and Functions ==
=== Main Power ===
----
Evaluation kit main power can be provided from either a Li-Poly battery, or a DC power source.
<blockquote>
==== Option 1 - DC only ====
Connector '''J6''' is the main DC power source of thе evaluation kit.
The DC power supply unit included with the evaluation kit provides 12V DC power to the system through '''J6'''.

==== Option 2 - Li-Poly Battery ====
Battery powered operation of the evaluation kit is supported through the main battery connector '''P19'''.
The evaluation kit is shipped with an accessory battery adapter allowing '''P19''' connection to custom batteries.
Please refer to [[SB-UCM:_Li-Poly Battery|battery specification]] for details on supported batteries.
<blockquote>

==== Main Battery Charging ====
This evaluation kit supports main battery charging when both power sources (Battery + DC) are available.
The '''DS1''' LED indicates battery charging is in progress.
Detailed status of the battery and charging process is available to software through I2C access to the SB-UCM on-board battery charger (U25 in SB-UCM schematics) and charging supervisor (U24 in SB-UCM schematics).
</blockquote>
</blockquote>


=== Serial Console ===
----
Serial console is available through USB interface, using micro-USB2.0 Type-B connector '''P7'''. Continue to [[SB-UCM: HOWTO: USB Console|USB console guide]] for USB interface setup instructions.



=== USB ===
----
All UCM-iMX7 USB ports are accessible with this evaluation kit:
# UCM-iMX7 Native USB Port 1 is available through the OTG connector '''P3'''.
#* USB Host connection: The micro-USB to USB type-A adapter included with evaluation kit (available for purchase [http://www.compulab.com/support/cables-connectors-accessories/ here]) allows usage of connector '''P3''' as a standard USB2.0 host port.
#* USB Gadget connection: A standard micro-USB cable (included with evaluation kit) enables connection of the evaluation kit as a USB gadget to the USB port of your host computer.
# UCM-iMX7 Hub USB Port 1 is available through the bottom port of the dual stacked USB2.0 connector '''P6'''.
# UCM-iMX7 Hub USB Port 2 is available through the mini-PCI-express connector '''P16''', enqabling connection of mini-PCIe form-factor USB devices such as 3G modems etc.
# UCM-iMX7 Hub USB Port 3 is available through the top port of the dual stacked USB2.0 connector '''P6'''.
# UCM-iMX7 Native USB Port 2 is accessible through the general purpose 100mil header '''P5''' . Using the CONUSB adapter included with the evaluation kit (available for purchase [http://www.compulab.com/support/cables-connectors-accessories/ here]), allows connection of standard USB2.0 devices to these ports. '''P5''' pins used the port are shown in table below

.

=== CAN ===
----
By default, only CAN1 interface is connected to the SB-UCM onboard CAN PHY and Isolator components with this evaluation kit.
# CAN bus nodes can be connected to evaluation kit header '''P5''' as described in [[SB-UCM:_HOWTO:_CAN_Connection|CAN node connection guide]].
{{note| Removing R143 + R145, then populating 0Ω resistors in R144 and R142 placeholders, enables connection of the CAN2 interface to SB-UCM onboard CAN PHY and Isolator components instead of CAN1}}



=== Ethernet ===
----
The kit features a single 1Gbps copper Ethernet port. The ethernet port is available through RJ45 connector '''P21'''.



=== PCI-Express ===
----
Plug your mini-PCIe device into the evaluation kit mini-PCIe connector '''P16'''. Full/Half size mini-PCIe boards are supported.



=== Wireless ===
----
<blockquote>
==== WiFi/Bluetooth ====
Connect the antenna (included with evaluation kit) to UCM-iMX7 connector J1 for WiFi and/or Bluetooth operation.

==== Cellular ====
USB and/or PCI-express interfaced cellular modems (2G/3G/4G etc.) can be plugged into connector '''P16''' (mini-PCI-Express) as explained below:
# Plug your modem into '''P16''' mini PCI-Express connector.
# Insert your micro-SIM card into the '''P13''' micro-SIM slot (only relevant if your cellular modem requires a sim card access while not featuring an onboard SIM slot).
</blockquote>



=== Display ===
----
Evaluation kit supports display interfaces listed below (not simultaneously). Selection of active display interface is set by software.
<blockquote>
==== LCD ====
Connect the LCD panel included with the evaluation kit the the system through the FPC connector '''P10'''. Consult the software documentation in order to make sure system is configured utilize LCD display on '''P10'''.


==== DVI ====
The DVI display interface is accessible through the HDMI connector '''J5'''. 


==== MIPI-DSI ====
The UCM-iMX7 MIPI-DSI two lane display interface is accessible through evaluation kit header '''P11'''.
This header enables simple connection (with jumper wires) to any MIPI-DSI enabled panel.
Please refer to SB-UCM schematics for detailed information on '''P11'''.


=== System ===
----
<blockquote>
==== Reset ====
Pressing the reset button ('''SW2''') triggers evaluation kit cold reset.

==== Boot Sequence Selection ====
Evaluation kit supports normal and alternate boot sequences. Detailed description of the sequences is available in the UCM-iMX7 reference guide.
:* '''Normal Boot Sequence:''' During early boot stages, UCM-iMX7 executes the U-Boot firmware flashed into the onboard SPI Flash.
:* '''Alternate Boot Sequence:''' During early boot stages, UCM-iMX7 attempts to execute U-Boot firmware (if available) flashed into an SD card (at micro-SD slot '''P8''') before falling back to U-Boot firmware pre-flashed onto the onboard SPI Flash.
# Pressing and holding the "Alternate boot select" button ('''SW3''') during power-up or cold reset forces execution if the "Alternative Boot Sequence".
# Populating the '''E1''' jumper, forces the "Alternate Boot Sequence" for every boot attempt.
# Indication of selected boot sequence is shown with the '''DS12''' LED. (ON = "Alternate Boot Sequence" enabled).

==== Power ON / Cycle ====
* A short press of the ON/OFF button ('''SW1''') while system is operational, generates an OFF request to be serviced by software.
* A long (>5Sec) press of the ON/OFF button ('''SW1''') while system is operational, unconditionally shuts down the system (same as simply removing power source).
* A short press of the ON/OFF button ('''SW1''') while system is off, triggers the system start-up sequence.

==== RTC ====
The evaluation kit RTC (implemented onboard UCM-iMX7) is powered by a coin cell battery. RTC power can be disconnected by:
* Removing the coin cell battery.
* Removing jumper '''E8'''.

To quickly discharge the RTC power, momentarily short pins 1 and 2 of jumper '''E8'''.
{{note|Never short pins 1 & 2 of jumper '''E8''' while system power is available}}
