Keep in mind that’s he card with a M.2 edge connector on one end. Mostly you’d be plugging that into something, at least to hook up the power/data lines. They sell “Note Carriers” for that, which end up making the combo bigger than that.
Here’s a pic of the note card plugged into their Raspberry Pi note carrier. That’s a standard 40 pin 0.1” spacing connector on the left, so it’s 2” plus the mounting holes in that dimension. 65x57mm and about 20mm tall for the stackable 40 pin socket+pins.
