==General==
 
* Official Hackers Manual ([http://www.openpandora.org/downloads/PANDORA_Hackers_manual_v101.pdf v1.01]) from OpenPandora Ltd, includes warnings about damage and warranties (or loss of).
 
 
 
==Board==
 
[[image:Board_rev5.jpg|thumb|Pandora PCB rev 5]]
 
The Pandora is based 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
 
 
 
===OMAP3530===
 
*OMAP35x: Main page on TI site[http://focus.ti.com/general/docs/gencontent.tsp?contentId=36915]
 
*OMAP3530 specific page[http://focus.ti.com/docs/prod/folders/print/omap3530.html]  ''This lists the features of the chip and has all the applicable Technical Documents''
 
 
 
====Other OMAP3530 Projects====
 
*Always Innovating Touch Book[http://www.alwaysinnovating.com/wiki/]
 
*Beagle Board Resources[http://beagleboard.org/resources] As it uses the same SoC, many BB resources are also relevant for the Pandora.
 
*Beagle Board Google Group[http://groups.google.com/group/beagleboard]
 
 
 
====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]
