Raspberry Pi – Specs and Features (Summary)

This is not an howto or a project per se, but it will definitly be reference in upcoming howto’s and projects.


What I present here is a summary of the Raspberry Pi specs and features:

Model A 
- 256MB RAM
- one USB port
- no Ethernet 
- Power: 500 mA  model

Model B
  - 512MB RAM
  - 2 USB ports
  - Ethernet port
  - Power: 700-1000mA

Model A&B
- Main Specs
   - 700 Mhz (Most devices will run happily at 800MHz)
   - 8 dedicated GPIO pins
   - UART (Rs232)
   - i2c bus
   - SPI bus with two chip selects (also in arduino)
   - i2s audio
   - Power - 3v3, 5v, and ground.
   - If you dont use UART, i2c, etc (and use all for GPIO)
      - Revision 1 - 17 GPIOs
      - Revision 2 - 21 GPIOs.
   - GPIOs can theoretically be expanded indefinitely by I2C or SPI bus.
 
- Physical     - Measures 85.60mm x 56mm x 21mm
    - It weighs 45g.

- Network
    - 100 Mbps (model B only)
    - Ethernet is attached via the USB 2.0 bus (Gigabit not possible)
    - No netbooting or pxe
   
 - Power
    - Tension: 4,75 Volts - 5,24 Volts (You can test it on the TP2 and TP1 contacts)
    - Maximum Power - 1 Amp (1000 mA)
    - GPIO pins can draw 50mA safely (all)
    - Individual GPIO pin can only safely draw 16mA
    - Camera module requires 250mA
    - Keyboards and mice can take as little as 100mA or over 1000mA!!! (be aware, and chose low power keyboards an mice)

- Video       
   - Raspberry Pi can record and play h.264 (mp4/mkv)    
   - Two additional codecs can be purchased (RBPi Store):
      - MPEG-2 - DVDs Codec
      - VC-1     - BlueRay Codec (Microsoft format - Blu-ray discs, Windows Media, Slingbox, and HD-DVDs)

- No real time clock (RTC)

- Camera Board (Omnivision 5647)
    - Is the only camera module that is compatible
    - Connects via the CSI-2 camera port using short ribbon cable
    - The  ribbon cable can be up to 4 meters
    - Connects to the Image System Pipeline (ISP)
    - Camera module (Omnivision 5647) specs are:
       - Photo - 5MP (2592×1944 pixels)
       - Video - 1080p 30Fps 1920x1080x30fps)
       - Power - 250mA
