This accessory is experimental. The latest hardware revision is either untested, incomplete, or broken. Capabilities are unproven. Form factor and design requirements may change entirely. Intended for use by hardware contributors.
TODO
- Copper pads under power supply
- Clean up and condense
- ESD Protection
Face Tracker (Headset-Agnostic Version)
Headset-agnostic face tracker. Can be used with Frame by using the USB-C port on the battery.
Current Isseus
Q1 is setup improperly, removing it and R10 as well as bridging the now empty pads solves the issue. Will fix in EV3 along with some changes to layout and LEDs.

Questions
How big is the Primis FaceTracker PCB?
It measures 95 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Primis FaceTracker use?
50 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, XC6206P122MR and XC6206P282MR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Primis FaceTracker KiCad files?
From the Nieko27/Frame-Workshop repository on GitHub, at the commit this page was made from: the board is KICAD Projects/Primis_FaceTracker/Primis_FaceTracker.kicad_pcb and its schematic KICAD Projects/Frame_FaceTracker/Frame_FaceTracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Primis FaceTracker design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
