SlimeVR-MOD

Introduction:

SlimeVR is a set of open hardware sensors and open source software developed by foreign experts and open sourced based on the MIT open source protocol , which can promote full body tracking (FBT) in virtual reality. SlimeVR does not require a base station, making wireless VR tracking economical and comfortable, and can be used for SteamVR's full-body tracking.

This project is the open source hardware of SlimeVR that I drew personally. Please go to the official github to view the software and firmware part or view the official DIY tutorial.

The main parts are:

ESP12F (ESP8266)

GY-BNO08X sensor module

TP4056 lithium battery charging IC

RT9013-33GB lithium battery voltage stabilizing IC

CH340K serial port IC

ESP8266 automatic download circuit

1200mah lithium battery

Circuit description

The circuit part includes automatic download circuit and manual download circuit respectively. There is no need to weld components numbered C7, R13, R12, RTS, FLASH in the manual download circuit part if there are no special needs.

Number U7 is a magnetic connector, which is reserved for subsequent 5-way magnetic chargers. You can also charge directly with a data cable. If you don’t want to use magnetic connectors, you don’t need to solder the components numbered U7 and D1.

The number BAT is the battery interface

Number U6 is the second sensor interface, which can be connected using a connector with a pitch of 2.54mm.

The serial port needs to be recognized after soldering the battery, so please turn on the switch after soldering the battery and then burn the firmware.

※: Now the price of GY-BNO08X module has increased to ridiculous levels, and the BNO085 sensor IC is also out of stock. When the BNO085 sensor IC is in stock, we will directly integrate the IC into the PCB, which will be much cheaper than using modules.
