Hopefully everything over in the thread should sort you out with the Launchpad Minis (Mk 3s in my case) as a grid, which I have been using happily with many scripts for a few months now. There may be some configuration tweaks for the minis required to match particular use cases (it’s been a while since I set mine up) such as midi device names to be aware of, and feel free to ask for assistance if you need it.
Norns is amazing, and even with a limited form of grid it becomes so much more playable.
