Overview ¶
Package rpi contains Raspberry Pi hardware logic. It is intrinsically related to package bcm283x.
Assumes Raspbian but does not directly depend on the distro being Raspbian. Windows IoT is currently not supported.
Physical ¶
The physical pin out is based on http://www.raspberrypi.org information but http://pinout.xyz/ has a nice interactive web page.

Pin as connect on the 40 pins extension header.
Schematics are useful to know what is connected to what: https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/README.md
The actual pin mapping depends on the board revision! The default values are set as the 40 pins header on Raspberry Pi 2 and Raspberry Pi 3.

P1 is also known as J8 on A+, B+, 2 and later.
