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.

Qwiic Distance Sensor (VL53L1X, VL53L4CD) Hookup Guide
The Qwiic Distance Sensor - VL53L1X is a time of flight sensor that is capable of several modes, as well as having a range of 4M. It's cousin VL53L4CD is also a time of flight sensor with similar characteristics but it has a range of about 1.3M. Let's hook it up and find out just how far away that thing over there is.
