I'm using JF PMOD in my hardware design and looks like pin descriptions in a manual are incorrect. I didn't get the whole picture yet, but signal routed to M19 which is supposed to be on Pin1 of JF PMOD, appear on Pin3; M17 appear on Pin4 instead of Pin2; M18 appear on Pin8 instead of Pin4.
Those M19,M17 and M18 - my outputs and the rest are inputs, so I can't figure out them easily.
Gary could you please verify it.
