This is the same as [[RPi_BCM2835_Pinout]], but showing the signal each pin connects to rather than the pin-name. The same disclaimers apply ;-)

And the corresponding signal connections for the Rev2.0 RaspberryPi boards are [[RPi_BCM2835_Signals_Rev2.0|here]] (the only differences are in A6, B5, C3, C4, C6 & D5).

Back to RPi_schematics_breakdown

Raspberry Pi GPU/CPU signal connections

This is the same as RPi_BCM2835_Pinout, but showing the signal each pin connects to rather than the pin-name. The same disclaimers apply ;-)
And the corresponding signal connections for the Rev2.0 RaspberryPi boards are here (the only differences are in A6, B5, C3, C4, C6 & D5).
