I’ve winkled the details of the Raspberry Pi’s GPIO pinout out of the hardware guys: no pretty pictures in this post, but a lovely information dump that those of you who solder for fun will enjoy getting your teeth into.
Top row, left to right:
Bottom row, left to right:
– all the UART, SPI and I2C pins can be reconfigured as GPIO if needed.
– some of the do-not-connect (DNC) pins will likely be replaced by
GPIO in a subsequent board revision.
We will not be making the boards with pins in place, in order to shave some cost off the build; you’ll have to solder them on yourself. I have to add the usual legal warning here that this pinout is provisional, subject to change if we decide something’s wrong or not optimal, and all that jazz. The likelihood of any changes is very small indeed, but do be aware that it’s there if you are using this information to build any add-on hardware before you get your hands on a Raspberry Pi.
