General
- Official Hackers Manual (v1.01) from OpenPandora Ltd, includes warnings about damage and warranties (or loss of).
Board
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[1]
- OMAP3530 specific page[2] This lists the features of the chip and has all the applicable Technical Documents
Other OMAP3530 Projects
- Always Innovating Touch Book[3]
- Beagle Board Resources[4] As it uses the same SoC, many BB resources are also relevant for the Pandora.

Cortex-A8
This processor is part of the ARM risc cpu family[6] that is licensed by a lot of hardware vendors. It has multiple command extensions as NEON (similar to MMX for x86 architecture)
- r1p1[7] Note: OMAP3530 uses rev1p2
- UPDATE: r2p2 Documentation [8] Note: OMAP3530 uses rev1p2

PowerVR
C64x+
Digital signal processors allow to do complex calculations within only a few cycles

Display
- Screen datasheet (TD043MTEA1)[17] 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. --[18]

Keyboard
- The keyboard is listed on p.20 of the hackers manual, and a more readable version is shown here.
Touchscreen
