Carrier Board Interfaces and Functions
Main Power
Evaluation kit main power can be provided from DC power source. Connector J2 is the 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 J2.
Serial Console
Serial console is available through serial over RS-232 using the P11 connector. A custom RS-232 cable is included with the evaluation kit.
USB
All of the CM-T335 USB ports are accessible with this evaluation kit:
- CM-T335 Native USB Port 0 (U1 option) is available through the OTG connector P19.
- USB Host connection: The micro-USB to USB type-A adapter included with evaluation kit (available for purchase here) allows usage of connector P19 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-T335 onboard USB hub ports (U4 option) are accessible through the P25, P26, P27 and P28 ports.
Ethernet
The kit features GbE copper Ethernet port. The Ethernet port is available through RJ45 connector P2.
Wireless
WiFi/Bluetooth
Connect both antennas (included with evaluation kit) to CM-T335 (WB option) connectors J1 and J2 for WiFi and Bluetooth operation.
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-T335 Linux demo image. Connect the LCD panel the evaluation kit through the FPC connector P5.
DVI
The DVI display interface is accessible through the HDMI connector J1.
System
Boot Sequence Selection
Evaluation kit supports normal and alternate boot sequences. Detailed description of the sequences is available in the CM-T335 reference guide.
- Pressing and holding the ALT.BOOT button during power-up or cold reset forces alternative boot sequence.
RTC
The evaluation kit RTC (implemented onboard CM-T335) is powered by a coin cell battery. RTC power can be disconnected by:
- Removing CM-T335 from SB-T335.
Multi functional signals access
UART
CM-T335 UART interfaces are partially accessible through headers P20.
Please refer to CM-T335 reference guide and SB-T335 schematics for details.
SPI
CM-T335 SPI interface signals are partially accessible through headers P20.
Please refer to CM-T335 reference guide and SB-T335 schematics for details.
I2C
CM-T335 I2C interface signals are partially accessible through headers P20.
Please refer to CM-T335 reference guide and SB-T335 schematics for details.
GPIO
Some of the CM-T335 GPIO signals are accessible through headers P20.
Please refer to CM-T335 reference guide and SB-T335 schematics for details.
