The Raspberry Pi is based on the Broadcom BCM2835 system on a chip, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU and was originally shipped with 256 megabytes of RAM, later upgraded (Model B & Model B+) to 512 MB.
Currently only rev 1 is supported.
GPIO Supported on pin 6,10,11,12,14,15,17,21
PWM Whilst the Raspberry Pi is meant to have 1 PWM channel this is currently not supported.
I2C The blacklist for the kernel module will need to be removed and the i2c-dev needs to be loaded.
SPI The blacklist for the kernel module needs to be removed and spidev loaded
