Revision 10199-V1.0 of the board has an incorrect pin labeling on the
silkscreen, presumably because the board was initially developed
for a different E180 module and the silkscreen was not updated when
populated with a different E180 module.
It is very likely that if newer revisions of the test board get
produced, they will use the same very systematical routing as revision
1.0 and only the silkscreen labeling will be fixed. Hence, documenting
the correct pin mapping will be useful even for newer revisions.
