Raspberry Pi, la board ideale per un VDR "diverso" ?

Hello
Anche se un po' presto ma, non voglio farmi fregare il 1. posto
questa board secondo me e molto interessante
componenti provisori :
SoC: Broadcom BCM2835 media processor system-on-chip featuring:
CPU core: ARM1176JZF-S ARM11 core clocked at 700MHz; ARM VFP.
GPU core: a Broadcom VideoCore GPU providing OpenGL ES 1.1, OpenGL ES 2.0, hardware-accelerated OpenVG 1.1, Open EGL, OpenMAX and 1080p30 H.264 high-profile decode. There are 24 GFLOPS of general purpose compute and a bunch of texture filtering and DMA infrastructure. Eben worked on the architecture team for this and the Raspberry Pi team are looking at how they can make some of the proprietary features available to application programmers
DSP core: There is a DSP, but there isn't currently a public API
RAM: 128MiB (Model A) or 256MiB (Model B) of SDRAM.
Micro USB power jack (5v)
SD/MMC/SDIO memory card slot (underside)
HDMI connector providing HDMI 1.3a out
Audio connector: 3.5mm stereo jack
Composite Video connector: RCA
Either 1x USB 2.0 (Model A) or LAN9512 (Data Brief | Data Sheet) providing 10/100Mb Ethernet and 2x USB 2.0 (J10: Model B)
DSI interface. Believed to be a 15-pin surface mounted flat flex connector (possibly no-fit).
MIPI CSI-2 interface. Believed to be a 15-pin surface mounted flat flex connector (possibly no-fit).
Expansion. 26-pin 2.54mm header, 15-pin 2.54mm header providing:
6-pin GPU JTAG (ARM11 pinout)
4-pin UART serial console, 3v3 TTL (debug)
~16 GPIOs at 3v3
2x I2C interface (3v3)
I2S interface
SPI interface (3v3)
ARM JTAG
Dimensioni della board (formato carta di credito) :
85.60mm x 53.98mm. Altezza 20mm.
Peso <40g
6 layer PCB
Anteprima PCB con layout : probabile uscita : dicembre 2011
costo :25$ per la versione A 35$ per la versione B

la tengo sott' occhio da un bel po'
