Processor
| TMS320DM355 Processor -> This processor is used in digital still cameras, digital photo frames, IP security cameras, video door bells, and other low cost portable digital video applications. It combines high performance MPEG4 HD (720p) codecs and JPEG codecs up to 50Mpixels per second, high quality, and low power consumption at a very low price point. DM355 processor
|
| NAND flash
| 2Gb Micron NAND Flash. +3.3V powered, 256M x 8-bit. Compatible with 1Gb NAND Flash
|
| DDR2 SDRAM
| 1Gb Micron DDR2 SDRAM (128MB). +3.3V powered, 8M x 16 x 8 banks
|
| Camera Interface
| VGA CMOS Image Sensor by Default, Optional: 1.3M, 2M, 3M and 5 Mega-pixel CMOS Sensors are supported
|
| Audio In/Out
| Low power stereo audio codec TLV320AIC3104 -> A 2.5mm standard stereo audio input jack is provided to receive stereo audio input
|
| JTAG port
| JTAG Debugging Port -> A 14 pin JTAG header is provided in order to facilitate spftware development and debugging in the board by using various JTAG emulators
|
| Serial Port RS-232
| UART Debugging Port -> Support for RS232 is provided by a 2.5mm stereo audio jack for access to an on-board RS232 transceiver. Access to the serial port requires a 2.5mm stereo audio jack to DB9 Female converter cable, which is an accessory part
|
| USB 2.0 Port
| USB 2.0 HS -> The LeopardBoard requires a mini-B to USB type-A cable. LeopardBoard can be accessed through USB cable and the device can be powered by USB port
|

|
| Power Management
| TPS65053 Power management chip -> Powerful 5-Channel Power Management IC with two step-down converters and 3 low-input voltage LDOs chip
|
| Power Input
| +5V Power Input -> 2.1mm I.D. x 5.5mm O.D. x 12mm Female
|
| Video Output Port
| PAL/NTSC Output -> A video jack is provided for composite video output. It supports NTSC or PAL output formats to a standard TV. The default is NTSC, but it can be switched to PAL through software configuration
|
| Network Interface
| Standard RJ-45 connector for 10/100 Mbps ethernet networks
|
| LCD/DVI Interface
| LCD/DVI Interface through adapter board -> LeopardBoard has a 50-pin connector, which is fully compatible with the DM355EVM
expansion connector; it supports an LCD daughter card or a DVI daughter card
