Raspberry Pi Model B {#rasppib}
====================
Raspberry Pi {#rasppi}
============
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.
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. The Raspberry Pi 2 is based on an armv7 CPU but shares a number of
similarities with the original.
Revision Support
----------------
Currently only rev 1 is supported.
Raspberry Pi A/B/A+/B+
Raspberry Pi 2 B
Interface notes
---------------
**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
Pin Mapping
-----------
This pin mapping refers to the first generation 'B' model Pi but gives an idea
as to what the values are from mraa. Note that there is an emum to use wiringPi
style numbers.
| MRAA Number | Physical Pin | Function |
|-------------|--------------|----------|
| 1 | P1-01 | 3V3 VCC |
