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.
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.

Parts:

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

Or one with a cover on AliExpress

28 AWG gauge wire from AliExpress

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.
Small (what Prohurtz uses): AliExpress
Large: AliExpress

This is our latest setup recommended for users with wired headsets such as the Valve Index.
Pros:
Cons:
Parts:
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
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.
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.
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.
Amazon alternative (note that you will have to manually remove the IR filter)
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
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
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)
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.
1x Hot glue or another form of glue.
