Required Equipment
To start measuring bio-data with the PiEEG XR, you will need the following parts in addition to the device itself:
| Item | Purpose |
|---|---|
| Power bank (5 V) | Supplies power to the PiEEG XR |
| USB-C cable | Connects the PiEEG XR to the power bank |
| VR headset | Runs the XR experience |
Power
The PiEEG XR is powered by a 5 V power bank connected over a USB-C cable.
[!IMPORTANT] Use only USB-C supplies rated for power delivery. For the most reliable connection, we recommend a USB-C to USB-A cable.

Headset
We recommend a headset with a built-in battery, so it can also supply power to the PiEEG XR.

Compatibility
The PiEEG XR works with Meta Quest, Meta Quest 3, PICO, and other headset models.
[!IMPORTANT]
The device housing and mask are configured for the specific headset model they were made for. For example, a unit built for the Meta Quest 3 fits only the Meta Quest 3.
If you want to adapt the setup for a different headset or mask, a DIY kit manual is coming soon. It will let you customize the configuration for any device and mask.
