Resources and Going Further
If you want more detailed information about the Wedge and the interfaces it breaks out, check out the following materials:
- To take a closer look at programming for the I/O on a Pi, in both Python and C, take a look at our Raspberry gPIo tutorial.
- If you want to use the synchronous serial interface broken out by the wedge, you can learn more in out I2C & SPI tutorial
- The design files for the PCB, and some WiringPi software examples can be found in the 40-pin Pi Wedge GitHib repository.
