This page collects information about Raspberry Pi's $25 Linux computer for Education, based on a new Broadcom media processor (Raspberry Pi are currently redacting the chip model number in comments on their forum) and featuring an ARM1176JZF-S core.

Events


Hardware

The first product is about the size of a credit card, and is designed to plug into a TV or be combined with a touch screen for a low cost tablet. The expected price is $25 for a fully-configured system.

Provisional specification

  • 700MHz ARM11 (ARM1176JZF-S) core
  • 128MB (Model A) or 256MB of SDRAM (Model B)
  • OpenGL ES 2.0
  • 1080p30 H.264 high-profile decode
  • Composite and HDMI video output
  • One USB 2.0 port provided by the BCMxxxx
  • SD/MMC/SDIO memory card slot
  • General-purpose I/O (About 16 3v3, brought out to 1.27mm pin-strip)
  • Optional integrated 2-port USB hub and 10/100 Ethernet controller (Model B)
  • Open software (Ubuntu, Iceweasel, KOffice, Python)

Components

  • Board size: Credit-card or smaller.
  • Weight: <37g
  • Currently 6 layer PCB; target: 4 layer


Manual

Documentation will presumably be available when the product is release (current target ~November 2011)

Schematic / Layout

Errata

Clocking

  • Provisional main CPU clock speed is 700MHz
  • No data currently released on the GPU or other component clock speeds

Power management

  • Target power consumption is <1W

DLP Pico projector

The boards have both Composite and HDMI outputs so should interface with a range od DLP Pico projectors on the market.

Interfacing to Raw LCD Panels

No data currently available.

Availability

Estimated availablility is End of November 2011.

Case

A protective case is an often-cited required accessory. Cases are likely to be offered both directly from Raspberry Pi and from 3rd party companies such as Special Computing.

Adapters

Provisional information is that the boards will feature a Coax-style DC Jack connector accepting 6-20v (or possibly 5-16v)

Expansion boards

It is likely that expansion boards will be offered both by Raspberry Pi Foundation and by 3rd parties.

BootRom

The boards do not include NAND or NOR storage - everything is on the SD card, which has a FAT32 partition with GPU firmware and a kernel image, and an EXT2 partition with the rootfs.

We're not currently using a bootloader - we actually boot via the GPU, which contains a proprietary RISC core (wacky architecture ;) . The GPU mounts the SD card, loads GPU firmware and brings up display/video/3d, loads a kernel image, resets the SD card host and starts the ARM.

You could replace the kernel image with a bootloader image, and that would work fine.


Code

Code and binaries for Raspberry Pi will be available at various places from launch.

Binaries

Source

Compiler

The Broadcom processor on Raspberry Pi contains an ARM v6 general purpose processor and a GPU of currently unknown origin. No data is currently available on other cores (if any) available in the BCMxxxx.

ARM

There is broad compiler support including gcc - please see ARM Compilers

DSP

It is currently unknown if there is a DSP present.

Development environments

Instead of just using compiler + editor, you can use complete image create "development tool chains" which integrate compiler, build system, packaging tools etc. in one tool chain.

OpenEmbedded

Eclipse

Meego

Android

EMBINUX

Mamona

Ubuntu

Debian ARM

GeeXboX ARM

Scratchbox
