ESP setup options:
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: Wired over USB Serial
Wired Capable ESPs:
- Seeed Studio XIAO Sense
- FREENOVE ESP32-S3-WROOM CAM Board
This is our latest setup recommended for users with wired headsets such as the Valve Index.
Pros:
- Much better performance and higher framerate up to 70 FPS with lower latency
- No conflicts with advanced FBT setups such as Vive or Tundra Trackers
- Can be wireless or wired
- Less soldering required compared to ESP32-CAM boards
Cons:
- Requires USB port i.e. on Valve Index and USB hub mounted on your headset
- Can be slightly more costly
- When in use with a Vive Facial Tracker or other bandwidth sensitive components, a MTT USB hub is required or the devices will be unusable (low FPS).
- Requires beta app versions until the v2.0 app is released
Option 2: Wireless over WiFi 2.4 GHz
Wireless Capable ESPs:
- Seeed Studio XIAO Sense
- ESP32-CAM
- FREENOVE ESP32-S3-WROOM CAM Board
This offers a good starting point as the ESP32-CAM boards are cheaper than wired capable trackers. However, they can be a bit more temperamental and if you are using a wired headset, they don't really make sense.
Pros:
- Less cables (power only)
- No issues with USB hubs
- Easier to flash
Cons:
- Requires two external antennas for optimal streaming quality
- Requires WiFi 2.4 GHz router or access point in reasonable proximity
- High risk of radio interference with FBT and other WiFi 2.4 GHz devices
- Uses more power and heats up due to radio power needs
