The powerblock arrived quicker than expected, and removing the mausberry script is easy enough.
so that's what I did.
I know that by default they use different pins, but that can be changed in the configuration settings or simply connect to the same pins.
The mausberry pins are labeled IN and OUT and the powerblock pins are labeled S1 and S2
so it is just a matter of testing if IN means S1 and if OUT means S2 - or the other way around.
that'll be a test for another day. For now it is working with the default powerblock installed bash.
On a side note, it would be nice if the 2x6 female header was offered optionally as unsoldered for those of us that don't use it and want the board to sit low and flat in the case.
