BEAGLE BOARD MEANS• Bring your own peripherals• Entry-level cost ($149/179)• ARM Cortex-A8 (superscalar)• Graphics and DSP accelerated• Linux and open source community• Environment for innovators
BEAGLE BOARD HISTORY• IT AS TWO VERSIONS 1)BEAGLE BOARD• 2)BEAGLE BOARD XM• Feb 2008: Rev A concept demonstrated at meeting with key kernel maintainers and open source developers at TIDC• Jun 2008: Rev B launched broad availability with Digit-Key• Mar 2009: First hands-on ESC BYOES training• May 2009: Rev C doubles RAM to 256MB• Jan 2010: Rev C4 bumps performance to 720MHz and resolves USB power supply stability issue• Jun 2010: xM Rev A board demonstrated at hands-on ESC BYOES training
BEAGLE BOARD WHY? SD USB Stereo in Stereo out Power DVI-D Note: Beagle Board can be powered from the alternate jack (as shown) or via USB
WHY PRODUCTION OF BEAGLE BOARDXMIN BEAGLE BOARD THERE IS NO OVER VOLTGE PROTECTION CIRCUIT.IT IS HAVING ONLY ONE USB,NO INSERTION OF MMC CARD,CAMERA HEADER,MMC3 EXPANTION,MCBSP,IT IS HAVING ONLY 256MB OF MEMORY AS COMPARE TO THE BEAGLE BOARD XM.

POP MEMORY a MCP (Multi Chip Package) that contains both the SDRAM andNAND Flash.IT IS MULTI CHIP PACKAGE.
SD/MMC CARDS. The SD/MMC connector is supplied power from the TPS65950 using the VMMC1 rail When a card is inserted into the SD/MMC connector, the Card Detect pin is grounded. This is detected on pin P12 of the TPS65950. An interrupt, if enabled, is sent to the OMAP3530 via the interrupt pin If an SD card is inserted into the SD/MMC connector and the write protect pin is active, the Write Detect pin is grounded
S-VIDEO CABLEAn S-Video cable can be connected to the BeagleBoard andfrom there is can be connected to a TV or monitor that supportsan S-Video input.IT SUPPORTS NTSC AN PAL FORMAT.NTSC MEANS “NATIONAL TELIVISION SYSTEM COMMITEE”.PAL MEANSIt can be changed via the Software.
DIFFERENCE BETWEEN NTSC AND PAL:• NTSC IT USES THE
MCBSPMcBSP2The multi-channel buffered serial port (McBSP) McBSP2 provides a full-duplex directserial interface between the OMAP3530 and the audio CODEC in the TPS65950
MCBSP1McBSP1McBSP1 provides a full-duplex direct serial interface between the OMAP3530 andthe expansion interface. There are 6 signals supported on McBSP1.
MCBSP3McBSP3 provides a full-duplex direct serial interface between the OMAP3530 and theEXPANSION INTERFACE.
DVI-D CABLEIn order to connect the DVI-D output to a monitor, aHDMI to DVI-D cable is required.This cable is not suppliedwith BeagleBoard but can be obtained through numeroussource.

RS 232 HEADER:-In order to access the serial port of the BeagleBoard a flat cable isrequired to connect to a PC. The adapter will not plug directly into thePC and will require an external Female to Female twisted cable (NullModem) in order to connect it to the PC. The ribbon cableis not supplied with the BeagleBoard but can be obtained fromnumerous sources.
AUDIO CABLES:A 3.5mm standard stereo output audio jack is providedto access the stereo output of the onboard audio CODEC.The Audio CODEC is provided by the TPS65950.A 3.5mm standard stereo audio input jack isprovided to access the stereo output of theonboard audio Codec.
