The GPIOs of the 10 Pmods (J10 to J17, J20, J21) are connected with 100 Ohm differential routing to the B2B connector. J21 is a pure I²C compatible Pmod, without additional signals. The other 9 are GPIO Pmods where despite J20 all others can be used as dual Pmods. By default VCCIO_35 is NOT connected. Via pin header J19 the variable bank power VCCIO_35 for the Pmods J10, J11, J12, J13, J14, J16 can be selected. Respect power regulator limits!
