Context: Varifocal
We need to make a board to deliver power to all of the various breakout boards, as well as the voice coil motors.
As a bonus, this board could have the MCU/IMU for tracking integrated, as well as the PWM output for the voice coils. This would make it essentially the motherboard of the varifocal headset.

The headset should be as standalone as possible. Current plans are all electronics are powered from within the headset. Only cable to the computer should be the display cable.
We are currently using the Northstar displays, display driver board, and SLAM functionality, which serves as it’s own separate system. It receives power from the same USB-C cable it receives data. This is currently completely separate from the Motherboard.
No plans currently. May change in the future.
We reached out to GEEPLUS for their offerings.
We chose both the 180 and 112 models to prototype with.
