= SPI connector pinout =

For the interconnect between the SPI masters and the SPI expansion boards BitWizard uses a 6-pin SPI cable.

The pinout is the same (or very similar) to the pinout of the 6-pin ICSP programming connector that lots of AVR boards have.

The connector is laid out as follows:

The board usually has pin 1 and six marked.

 You could use other pins, but then you have to make a software SPI implementation. This is not too difficult, but might be neccesary if something else is already on the SPI pins. On the other hand, you might be able to still use the hardware SPI module by just moving the "SS" pin somewhere else.
+Arduino tells me that with differing chips being used as the "heart" of the module, the SPI pins are always available on the connector marked "ISP". The pin 5 or slave select is connected to the reset line, so it is not available to drive external slave select.
+On BitWizard Raspduino and ftdiatmega boards you can chose if that connector becomes SPI out or ISP.
