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.
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.
