This project is for a Raspberry Pi expansion board to accommodate a Digi XBee ZB SMT board.
The main intention of targeting the ZB SMT is so that the module can be driven over the SPI bus instead of using the UART. This has several advantages, one of which is it does not use up the UART so that it can still be used for other functionality.
The expansion board / backpack is able to host a non-SMT module using the standard 2mm header. Note that it is impossible to use SPI for modules connected using this header as the pins are not connected.
Solder jumpers are available to select which SPI chipselect line to use, to connect the ZB UART to the Raspberry Pi's UART and to connect GPIOs to various ZB pins (DTR/SLEEP_RQ and INTR).
