ESP8266 Motion Capture Devices for SlimeVR Ecosystem
Thinnest SlimeVR Tracker!
Full SMT PCB operating in MPU-6500 6DoF mode
Operate with all 5V chargers, including C to C PD chargers.
You can use it simply by ordering it from the fabricator
It is because of the start-up calibration of the MPU-6000 series.
When the MPU first powers up, the DMP measures the static noise, but this needs to be done on every boot. In other words, to reboot the tracker in-game, you must detach it from your body. Not only does this strap adapter help make it very convenient, but it is also a great help in tracker maintenance!
It only takes 10 seconds for you to assemble the tracker sensor and adapter, and less than 30 seconds to assemble all the trackers to your body :P
It is eco-friendly to save the life of Velcro straps and easily replace broken adapters.

The thinner the tracker, the closer the IMU is to the bone and the better the tracking accuracy. It is less affected by inertial force in fast movements.. Above all, it is comfortable when lying on the bed facing the tracker!
This hardware is licensed under the CERN-OHL-P v2 license, which is a permissive, non-viral and non-reciprocal open hardware license. Unlike software licenses like MIT and Apache 2.0, it better handles the nuances of hardware and protects both the licensor and licensee from patent lawsuits.
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in this work by you, shall be licensed as above, without any additional terms or conditions.
Note that as part of the CERN-OHL-P v2 license, recipients of manufactured hardware must also receive notice of the above license. One such method of conveying the notice is to include a link to the original source repo, or printing "Licensed under CERN-OHL-P v2" on the PCB silkscreen. For more info, see here.
This is conceptually similar to the MIT/Apache 2.0 Licenses, where the original license must still be included as a notice even when the source is modified and subsequently relicensed under different terms.
