Getting Started

Follow these steps to set up OpenGlass:


  1. Gather the required components:

  2. 3D print the glasses mount case using the provided STL file.

  3. Open the firmware folder and open the .ino file in the Arduino IDE.

    • If you don't have the Arduino IDE installed, download and install it from the official website.
  4. Follow the software preparation steps to set up the Arduino IDE for the XIAO ESP32S3 board:

    • Add ESP32 board package to your Arduino IDE:
      • Navigate to File > Preferences, and fill "Additional Boards Manager URLs" with the URL:
      • Navigate to Tools > Board > Boards Manager..., type the keyword esp32 in the search box, select the latest version of esp32, and install it.
    • Select your board and port:
      • On top of the Arduino IDE, select the port (likely to be COM3 or higher).
      • Search for xiao in the development board on the left and select XIAO_ESP32S3.
  5. Before you flash go to the "Tools" drop down in the Arduino IDE and make sure you set "PSRAM:" to be "PSRAM: "OPI PSRAM"

Like this

  1. Upload the firmware to the XIAO ESP32S3 board.


  1. Clone the OpenGlass repository and install the dependencies:

    git clone
    cd openglass
    npm install

    You can also use yarn to install, by doing

    yarn install
  2. Add API keys for Groq and OpenAI in the keys.ts file located at

  3. For Ollama, self-host the REST API from the repository at and add the URL to the keys.ts file.

  4. Start the application:

    npm start

    If using yarn start the application with

    yarn start

    Note: This is an Expo project. For now, open the localhost link (this will appear after completing step 5) to access the web version.
