With the qualification that this now-deprecated (but not replaced and not likely to go away) I/O method works: Digital output to pins on a Pi Zero W with MMB4L

One reason this is deprecated is that there is nothing in Linux to prevent a program from trying to do I/O on a pin which another program is already using. For hobby use cases, this issue can probably be ignored. (I don't remember whether there is any clean-up if a program has failed.)
