- Official Hackers Manual (v1.01) from OpenPandora Ltd, includes warnings about damage and warranties (or loss of).
The Pandora is based upon OMAP3530 and DM3730 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

Two usb host ports. Bluetooth,two SD slots with SDIO capability, and a serial UART for adding whatever additional widgets you want (such as a USB GPS system). Solder pads were designed into the PCB for "hacking" in extra internal hardware.
RTC and RS-232?
It has RTC and RS-232 (CMOS level)
