Parts List

CAUTION

Please note that no hardware has been fully set in stone, all purchases are at your loss if hardware changes.

This page will include a basic part list for building an EyeTrackVR setup

NOTE

It is good practice to buy more than needed in some cases, namely cameras,programmers and ESPs. This reduces the risk of a DOA (dead on arrival) causing a delay.

ESP setup

DANGER

There are two primary categories of trackers supported: wireless and wired.

It's super important that you really look at all your options and consider your use case before making a decision.

Option 1: Wireless over WiFi 2.4 GHz

This offers a good starting point as the ESP boards are cheaper than wired capable trackers. However, they can be a bit more temperamental and if you are using a wired headset, they start to make less sense.

Pros:

  • Wider user adoption and greater support
  • Low weight, less cables, easier to manage

Cons:

  • Requires two external antennas for optimal streaming quality
  • Requires WiFi 2.4 GHz router or access point in reasonable proximity
  • Risk of radio interference with FBT and other WiFi 2.4 GHz devices
  • ESP32-CAM uses more power and heats up due to radio module power needs

Parts:

  • 2x ESP-CAM-32 modules

AliExpress

  • 1x ESP-CAM programmer / MB

AliExpress
Amazon for 3 ESP32-Cams and programmers without the proper cameras

  • 1x USB type-A male port to power both ESPs

Bare breakout on AliExpress
Amazon

Or one with a cover on AliExpress
Amazon

  • 1x Lower gauge wire to power ESPs

28 AWG gauge wire from AliExpress
28 AWG Amazon

  • 2x External antennas for ESPs

Required if you're running vive/tundra full body tracking or having issues with streaming. See the full build guide on how to configure the ESP board for antenna use.

Large: AliExpress

  • 2x-4x Heatsinks (Optional)

AliExpress (14mm for ESP, 8mm for voltage regulator)

Option 2: Wired over USB Serial (in beta)

This is our latest setup recommended for users with wired headsets such as the Valve Index.

Pros:

  • Much better performance and higher framerates up to 70 FPS with lower latency
  • No conflicts with advanced FBT setups such as Vive or Tundra Trackers
  • No heatsinks required due to lower power consumption and heat emission
  • Can be wireless or wired
  • Less soldering required

Cons:

  • Requires USB port i.e. on Valve Index and USB hub mounted on your headset
  • Can be more costly

Parts:

  • 2x ESP32-S3 modules

2x SeedStudio XIAO ESP32-S3 Sense Modules (Recommended) Very small size, lower price in some cases. SeedStudio

OR

2x Freenove ESP 32-S3 WROOM
Much larger, price may be higher than the XIAOs Amazon

  • 1x USB 3.0+ hub

Ensure that it is of good quality, lightweight, compact in size, and I suggest including three ports - one for the face tracker and two for ESP32-S3 boards. Ensure that you acquire appropriate USB-A to USB-C adapters wherever required, such as for the Valve Index which has only one USB-A port.

  • 2x USB C cables (as short as possible) to connect both ESPs

As the ESP32-S3 has USB-C connectors, you may require some USB-C to USB-A cables depending on your USB hub. It's worth noting that the HTC Face Tracker requires a USB-C port, so you may need to consider this requirement as well.

DANGER

Irrespective of whether you opt for a wired or wireless setup, additional components will be required to set up eye tracking cameras around your headset's lenses.

The list below remains the same for both wired and wireless setups.

Camera Parts:

If the cameras are Dead on Arrival (DOA), keep in mind that you can swap the lenses with the ones that come with the stock cameras that were included with the ESP32 boards.

There is an experimental option to purchase OV2640 120° FOV cameras and manually remove the IR filters. This can result in a clearer view of the eye, but it's not a default recommendation.

  • 2x OV2640 160° FOV IR / Night vers 75mm (850nm)

AliExpress

Amazon alternative (note that you will have to manually remove the IR filter)

  • 1x Higher gauge wire to power IR emitters

34 AWG AliExpress

  • 2x Camera cable extensions

Certain mounts may require a cable extension (ex: MUTE's frunk mod) To use a mount like that you will need a cable and a connector for each camera. Headsets like the Quest 2 do not require extensions.

Cables (select 0.5mm pitch type A) AliExpress (200mm for MUTE's)

Connectors (select 24P) Aliexpress

IR Emitters

If you do not want to source things from multiple places or save money and time on assembly, you can buy an official LED kit on our store:
Pre soldered kit
Raw component kit

Alternatively you can source the parts yourself:

  • 4x Unfocused SMD IR emitters
    (Recomended) from LCSC here.
    (Alternative) from Digikey here.
    The difference between them is the ones from LCSC are rated for lower power, which means in the event of a short or mishap they should be safer, as well as being smaller in footprint, hence why they are recommended.
NOTE

The smaller ones can not be soldered at temps above 245C or they will burn. Low temp solder is recommended.

DANGER

If they look like something you would find in a TV remote, do NOT use them. Even if you think you can alter them THEY WILL NOT WORK AND PUT YOU AT RISK. If you aren't exactly sure what you are doing, buy them from the LCSC or Digikey link.

DO NOT BUY FOCUSED ONES!

  • 4x IR emitter PCBs (highly recommended) Gerber files and schematics located here.

  • 4x 350ohm 1206 SMD resistors for IR emitters (If you are not using PCBs for the emitters then buying regular through-hole resistors is acceptable)

  • 357 ohm Digikey here

  • 348 ohm LCSC here

This ensures you get the correct IR emitter parts. If you are a Patreon please check out discount codes available to you, and also check out unit pricing.

3D Printed Mounts

Mounts with a next to them are the recommended mounts for the respected hmd. This is based on user feedback on what works best for most people.

Other Headsets

If you own another headset not listed above, that means there are no mounts designed for them yet. If you have basic skills in modeling or think up a solution to mount cams and emitters, please try to make a mount and then let us in the discord know so it can be added here. Any headset that can fit the camera is potentially compatible. If you are willing, give it a shot to design a mount for the rest of the community.

Check out our basic guide on making your own mount here.

TIP

If you have a headset mount that is not listed above, please let us know in the discord so it can be added here.
