The i2secho example cannot be used on CC13XX due to pin incompatibilities between the launchpad and the audio booster pack.

The BoosterPack does not need to be connected directly to the LaunchPad. You can sit them side-by-side and connect with jumper wires. We just need to update the documentation and Board files to show which wires to connect. We've done this for other examples where the BoosterPack has pin conflicts with LPs
