Teardown

Einleitung

This teardown illustrates how to deconstruct the Acer MR Headset (DE). This teardown also identifies some of the components within the HMD, and is open to any edits or suggestions for unidentified elements.

Werkzeuge

Schritt 1

Acer Windows Mixed Reality Headset Developer Edition Specs:
Two high-resolution liquid crystal displays at 1440 x 1440
2.89” diagonal display size (x2)
Front hinged display
4.00m cable
Built-in audio out and microphone support through 3.5mm jack
Single cable with HDMI 2.0 (display) and USB 3.0 (data) for connectivity

Schritt 2

Remove nose clip
Pull the foam from the velcro on the headset

Schritt 3

Remove the 8 Screws holding the mold to the headset
Pop 4 clips on the bottom of the headset with the spudger and begin to spread the mold from the headset.
4 more clips are on the top side to fully pull off the mold

Schritt 4

Pop the top clips up with the plastic spreader.
there are two clips along the front edge
There is one more clip in the back corner near the lenses

Schritt 5

Release the clip along the bottom edge with the spudger. There is an opening in the side of the wall of the clip that allows room for the spudger to help separate the lens cap from the carriage

Schritt 6

It was easier splitting the cover on the side arms open with the spudger and work your way towards the front
Pop the nine clips on the top of the headset
Release the bottom five clips on the headset

Schritt 7

Remove the four screws in the corners of the lens
Remove tape connecting the ribbon cables to the PCB
Unplug the lens from the PCB

Schritt 8

Remove the four screws for the camera cable connector
Remove the five screws on the PCB

Schritt 9

Unscrew the two screws connecting the cable to the PCB
Cypress CYUSB3064-BZXC SuperSpeed USB Bridge Controller
Cypress CYUSB3304-68LTXI HX3 USB 3.0 Hub
STMicroelectronics medium-density STM32F103C8 performance line microcontroller.
Spectra7 VR8050 USB 3.0 Cable Equalizer
Spectra7 HT8181 HDMI 2.0 Cable Equalizer

Commented in your the HP XR headset not having a complete component identification, including those the process the cameras that make up the parallax inside/out positional tracking.

It it possible to receive the board when it’s brocken?

Is it possible to order the usb hdmi cable from somewhere mine was cut.

Schritt 10

Unscrew the 8 camera screws in the corners
Cameras were not easily identifiable, however, they looked identical to the cameras we found in our HP MR HMD teardown. Also had similar part numbers to the the Microsoft Surface 3 rear camera.

Schritt 11

Remove 6 screws
Peal tape on the top of the films and pull back the films
You can then remove the 2 high-resolution 1440x1440 liquid crystal displays.
Lenses: The lenses appear to be fresnel on the inside but smooth on the outside.

The ridging on Fresnel lens is not a process. A Fresnel lens has ridges due to the way Fresnel lenses work and most are smooth on one side. So the actual description is these are Fresnel lenses with a FL approximately 35mm (don’t remember the exact number I came up with). I don’t have any of the other specs, like physical/chromatic curvature. The are also about 45mm at their widest point, making the smaller than both the Oculus and HTC/Vive lenses.

I have not personally had a chance to review or tear-down the Samsung Odyssey, which not only have larger OLED displays, but use aspheric PMMA lenses that are part of the reason for the sharper viewing experience.

This is fantastic thank you! Any plans on tearing down the other four MR headsets from Microsoft?

I’m curious, where are the the eye displays? And are they purchasable? I want to replace the eye display, because one in the left eye is glitching out.

Hi there,

I am wondering if anyone knows the components I have highlighted.

My HP WMR unit had a power surge and has burnt out most of these components.

A good electrical engineer friend of mine has cast a close eye over all the other components on the board, showing no physical damage (which I know doesn’t mean that they all ok).

I live in hope that I will be able to repair my WMR headset, as I have myself had plenty of experience with SM components.

Just identifying the values of these components is proving to be mighty tricky!

I believe (A) 6 pin “EDVGA” are voltage regulators - SOT23-6?

(B) Transistor? - “NA ID9” ?

Appreciate any help :)
