Hi @nunaisi ,
Welcome to the community!
You can't create a default board that will get oped when starting or opening Trello from your browser or app.
If you are using an app the last board that you have opened before closing the app that board will open when you open the Trello app for the next time!
If you are using a browser and visiting Trello.com you will get to see the home screen.
The best option you can try is to use a browser and bookmark your favorite board that you want to be open when you visit Trello!
