## Configuring the NeuropixelsV2e headstage

The `HeadstageNeuropixelsV2e` operator is set to configure the NeuropixelsV2e Headstage; this can enable streaming of electrophysiology data from a Neuropixels 2.0 probe and orientation data from a Bno055 IMU. This is accomplished in the NeuropixelsV2e Headstage example workflow by leaving all of the `HeadstageNeuropixelsV2e` properties set to their default values.
