Interfaces and Functions

Main Power

Evaluation kit main power can be provided from either a Li-Poly battery, or a DC power source.

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 battery specification for details on supported batteries.

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).

More Details: Connector J6, Connector P19, Battery Specification.

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 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 RS-232 console guide for RS-232 interface setup instructions.

USB

Both CM-T43 USB ports are accessible with the evaluation kit:

  1. 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.
  2. CM-T43 USB Port 1 is available through one of the following connectors, depending on the state of jumper E7.
    • E7 not populated: Only Dual stacked USB2.0 connector P6 and mini-PCI-express connector P16 are enabled.
    • E7 populated: Only USB2.0 connector P26 is enabled.

More Details: Connector P3, Connector P6, Connector P16, Connector P26.

CAN

CAN bus nodes can be connected to evaluation kit header P5 as described in CAN node connection guide.

More Details: Connector P23, Connector P5, CAN node connection guide.

Ethernet

The kit features two 1Gbps copper Ethernet ports.

Primary Ethernet

The primary Ethernet port is available through RJ45 connector P21.

Secondary Ethernet

The secondary Ethernet port is available through RJ45 connector P22.

More Details: Connector P21, Connector P22.

Wireless

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.

Cellular

USB interfaced cellular modems (2G/3G/4G etc.) can be plugged into connector P16 (mini-PCI-Express) as explained below:

  1. Remove jumper E7 to enable USB interface on P16. DS6 LED indicates USB interface availability at P16.
  2. Plug your modem into P16 mini PCI-Express connector.
  3. 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).

More Details: Connector P16, Connector P13.

Display

Evaluation kit supports display interfaces listed below (not simultaneously). Selection of active display interface is set by software.

LCD

LCD panel (included with evaluation kit) is the display enabled by default with CM-T43 linux demo image. Connect the LCD panel to 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.

More Details: Connector P10, Connector J5, Connector P11.

System

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.
