I/O Connection
All pins to the module are available through standard pin rows using a pitch distance of 100
mils (2.54 mm). These pins are connected to 4 x 10 pins holes named P4 to P7. The table
below gives an overview of the edge connectors and their logical signals. Details on the
pinning can be found in module datasheet.
