Module Connectors, X28 and X29
The development board provides two 10-pin, 2.0mm connectors, X28 and X29, supporting a
Digi XBee module.
The XBee serial port is shared with UART port 3 on the development board. Two jumpers (J30
and J31) are used in the development board to select the connector where serial port 3 will
be available. Refer to the “Jumpers” section of this document for more information.
The table below shows the pinout of the XBee module connectors.
