= 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.

<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-SOM-T43 on-board battery charger (U25 in SB-SOM schematics) and charging supervisor (U24 in SB-SOM schematics).
</blockquote>
</blockquote>

== Serial Console ==
Serial console is available through one of the following interfaces:
* Serial over USB using micro-USB2.0 Type-B  '''P7''' connector. Continue to [[SB-SOM: HOWTO: USB Console|USB console guide]] for USB interface setup instructions.
* Serial over RS-232 using the  '''P8''' connector with custom RS-232 cable (included with the evaluation kit). Continue to [[SB-SOM: HOWTO: RS-232 Console|RS-232 console guide]] for RS-232 interface setup instructions.

== USB ==
Both CM-T43 USB ports are accessible with this evaluation kit:
# CM-T43 USB Port 0 is available through the  OTG connector '''P3''' (only USB2.0 part of the connector is utilized).
#* USB Host connection: The micro-USB to USB type-A adapter (included with evaluation kit) 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.
# CM-T43 USB Port 1 is available through one of the following connectors, depending on the state of  jumper '''E7'''.
#*  '''E7''' <u>not</u> populated: Only Dual stacked USB2.0  '''P6''' connector and  '''P16''' mini-PCI-express connector are enabled.
#*  '''E7''' populated: Only  '''P26''' USB2.0 connector is enabled.

== CAN ==
CAN bus nodes can be connected to evaluation kit  header '''P5''' as described in [[SB-SOM:_HOWTO:_CAN_Connection|CAN hardware connection guide]].

== Ethernet ==
The kit features two 1Gbps copper Ethernet ports.

<blockquote>
=== Primary Ethernet ===
The primary Ethernet port is available through  RJ45 connector '''P21'''.

==== Secondary Ethernet ====
The secondary Ethernet port is available through  RJ45 connector '''P22'''.
</blockquote>

== Wireless ==
<blockquote>
=== WiFi/Bluetooth ===
Connect both antennas (included with evaluation kit) to CM-T43 connectors J1 and J2 for WiFi and/or Bluetooth operation.
=== NFC ===
Connect your NFC antenna to CM-T43 connector J3 NFC antenna connector.
</blockquote>

== Display ==
Evaluation kit supports display interfaces listed below (not simultaneously). Selection of active display interface is set by software.
<blockquote>
=== LCD ===
LCD panel (included with evaluation kit) is the display enabled by default with [[CM-T43:_Linux:_Debian|CM-T43 linux demo image]].
Connect the LCD panel the evaluation kit through the FPC connector  '''P10'''.


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


=== LVDS ===
The LVDS display interface is accessible through evaluation kit  header '''P11'''.
This header enables simple connection (with jumper wires) to any LVDS panel.
Please refer to SB-SOM schematics for detailed information on  '''P11'''.
</blockquote>

== 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 CM-T43 reference guide.
* Pressing and holding the  ALT.BOOT button ('''SW3''') during power-up or cold reset forces alternative boot sequence.
* Populating the  '''E1''' jumper, constantly forces alternative boot sequence.
* Indication of selected boot sequence is shown with the  '''DS12''' LED.

=== Power ON / Cycle ===
* Pressing the  PWRDn button ('''SW1''') generates a wake/power-on request.
* Pressing and holding this button results in constant power-cycling of evaluation kit (8 seconds interval by default).

=== RTC ===
The evaluation kit RTC (implemented onboard CM-T43) 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'''.
</blockquote>

== Multi functional signals access ==
<blockquote>
===Camera===
Part of the CM-T43 camera interface signals are accessible through the evaluation kit  '''P18''' header.

Please refer to CM-T43 reference guide and SB-SOM schematics for details.

=== UART ===
CM-T43 UART interfaces are partially accessible through headers  '''P4''',  '''P5''' and  '''P18'''.

Please refer to CM-T43 reference guide and SB-SOM schematics for details.

=== SPI ===
CM-T43 SPI interface signals are partially accessible through headers  '''P4''',  '''P5''' and  '''P18'''.

Please refer to CM-T43 reference guide and SB-SOM schematics for details.

=== I2C ===
CM-T43 I2C interface signals are partially accessible through headers  '''P4''',  '''P5''' and  '''P18'''.

Please refer to CM-T43 reference guide and SB-SOM schematics for details.

=== GPIO ===
Some of the CM-T43 GPIO signals are accessible through headers  '''P4''',  '''P5''' and  '''P18'''.

Please refer to CM-T43 reference guide and SB-SOM schematics for details.
