cores will not align perfectly with the typical Pmod pinouts for these interfaces. This means that
UART or I2C devices connected to this Pmod may require some of the pins to be swapped
around externally using individual wires between the DSDB and the Pmod.
MXP Connector
The myRIO Extension Port (MXP) Connector is a standard connector interface designed by NI
to provide an interoperable ecosystem of educational add-ons. This connector was included on
the DSDB to provide the Zynq with access to these add-ons. Figure 21 shows the signals on the
DSDB MXP connector.
