Pandora PCB rev 5

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

OMAP3530 (600MHz units)

• OMAP3xxx: Main page on TI site[1]

• OMAP3530 specific page[2] This lists the features of the chip and has all the applicable Technical Documents

Cortex-A8

This processor is part of the ARM risc cpu family[7] that is licensed by a lot of hardware vendors. It has multiple command extensions as NEON (similar to MMX for x86 architecture)

• r1p1[8] Note: OMAP3530 uses rev1p2
• UPDATE: r2p2 Documentation [9] Note: OMAP3530 uses rev1p2
• NEON instruction set [10]
• NEON memory hazards[11]

Connectivity

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) [17]
