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.

pin function remark
1 MISO Master In Slave Out
2 VCC power
3 SCK Shift Clock
4 MOSI Master Out Slave In.
5 SS Slave Select
6 GND Ground 0V

The connector is laid out as follows:

1 2
3 4
5 6

The board usually has pin 1 and six marked.
