OMAP4460 Pandaboard ES开发系统

PandaBoard ES has an updated OMAP4 PandaBoard with the OMAP4460 processor from Texas Instruments. The development board features two ARM Cortex-A9 (M3) cores that can clock up to 1.2GHz, compared to the dual-core 1GHz cores on the original PandaBoard with the TI OMAP4430. In addition to all the existing features of the OMAP4430 processor-based PandaBoard, the PandaBoard ES also has a DSI expansion header, Bluetooth® low energy-capable WiLink™ 6.0 combo connectivity module and a switch to control bootorder. Like the original PandaBoard, the PandaBoard ES is ideal for the development and enhancement of feature-rich mobile platforms and products and can support Linux-based operating systems. The new PandaBoard ES is software-compatible with the original PandaBoard. Additional information about the board and its technology capabilities can be found at pandaboard、org
