| [[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

| |
| *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]
