Nope.  Is it really outputting PPS 10 times a sec?  Not much point
to that.

Yup.

I'm looking at the data sheet.  It says 1PPS, not 10PPS.  So I suspect your
rpboelm is eleswhere.

What version of gpsd and what command line are you using to start
it.  Try high debug levels like this:
        gpsd -nD 6 /devv/ttyS0 |& fgrep PPS
