The Pandora is based upon the [[Beagle Board]] layout. It bases upon a OMAP3530 System-on-a-chip, that includes a whole family of processors in one single chip:
 
*[[ARM]] Cortex-A8 CPU
 
*PowerVR SGX graphics core
 
*C64x+ DSP core

===Cortex-A8===
 
This processor is part of the [[ARM]] risc cpu family[http://www.arm.com/products/processors/cortex-a/cortex-a8.php] that is licensed by a lot of hardware vendors. It has multiple command extensions as [[NEON]] (similar to MMX for x86 architecture)

==Display==
 
*Screen datasheet (TD043MTEA1)[http://beyondinfinite.com/lcd/Library/Toppoly/TD043MTEA1.pdf] The Pandora uses the display from the Archos 605 Media Player. However, on the Archos LCD the pinout is reversed as well as the cable having a 45 degree angle which would make it fail to line up with the Pandora LCD cable in the lid. --[http://boards.openpandora.org/index.php?/topic/3114-replacement-lcds/page__p__53657#entry53657]
