BeagleBoard

The Beagle Board is a low cost single-board computer based on the OMAP3530 SoC from Texas Instruments. The hardware design is free. It can be downloaded free of charge, which makes it possible to produce the board itself. In his mind in mid-2008 the Beagle Board met with a great response in the media.

Hardware

In addition to an ARM Cortex- A8 processor contains the OMAP3 system-on -a-chip and a TMS320C64x DSP and a GPU of PowerVR Technologies. The graphics output via HDMI or S-Video. Other connections include USB, RS -232, SD Card, JTAG and stereo input and output. The board can be powered via USB or an AC adapter with 5V either. Due to its low power consumption, it does not require additional cooling. It has 256MB of NAND flash memory and 256 MB of memory ( the first revisions had only 128 MB of RAM ). It can be from NAND memory, from the SD card, boot from USB or the serial interface.

Available Linux distributions

Some Linux distributions have previously been ported to the BeagleBoard, so among other things angstroms and Maemo. As a result, the BeagleBoard is also suitable for the development of software for the Maemo -based Nokia N900 smartphone.

Development

BeagleBone Black

Since April 23, 2013 at a price of 45 U.S. dollars is the BeagleBone Black available. Among other things, it offers 512 MB RAM, clocked at 1 GHz Sitara AM3359 ARM Cortex- A8 from Texas Instruments, in contrast to its predecessor, the derived in a compact version for hardware hackers from BeagleBoard BeagleBone, a micro - HDMI port and 2 GB eMMC Flash memory on board. Native Angstrom Linux is installed in eMMC, which allows immediate start of the board. The system supports Android ( rowboat ), Ubuntu, Debian, openSUSE, and Angstrom, and several other operating systems such as FreeBSD, OpenBSD, QNX, and Windows Embedded.

Variety of expansion boards ( Capes ) are available for the BeagleBone, which greatly expand its functionality. A single cape is attached to the double row, 46 pins comprehensive expansion interface on the Beagle Bones and offers itself is a necessary interface to the expansion using capes. A BeagleBone can be expanded with up to four Capes simultaneously.

XM version

Since 2010 there is a new version of the Beagle xM boards, which has, among other things, 512 MB RAM and 4 x USB 2.0.

PandaBoard

End of October 2010, the Panda Board was presented. It is, like the Beagle Board on an exposed ARM architecture and has been updated over the first version of the Beagle Board with respect to its hardware. It is, for example, a dual-core processor (OMAP4460 SoC from Texas Instruments ) with 1 GHz, 1 GB RAM, three video outputs ( two used in parallel, such as DVI -D and HDMI) as well as LAN, Wi-Fi and Bluetooth equipped. Despite the significant increase in power, it is offered at a slightly higher price than the original version of the BeagleBoard, but even without flash memory.

Distribution

Originally, the BeagleBoard was sold exclusively through Digi -Key, there are now more options with respect and in Germany. Several manufacturers produce compatible boards.
