| Raspberry Pi Camera Module Cables - Round? |
| << < (2/2) |
| amyk:
You can create your own round cable from suitable lengths of wire and a bit of manual effort. I'm not sure how much bandwidth it needs to have, but looking at the FFC I assume twisted pairs for the signal and power should be OK. |

Those old rounded IDE cables did exactly what the cable in the picture that wrapper posted does. They cut the ribbon into segments and sleeved the result. I only used those many years ago, and only once or twice, so I do not remember if that kind of construction had any influence on the performance. |

Doubt you're going to find a cable that's smaller than what you could coil an FFC to. Maybe the cables they use for LCDs in laptops, but you still have teh issue of passing a connector through the hole If you remove teh stiffner you could maybe curl it into a spiral to get through a significantly smaller hole than the width of the cable. One nice thing about FFC cables is they don't need a hole any bigger than the cable to pass a connector through, you just need a long, thin hole. |

CSI-2 is a high speed differential interface with controlled-impedance pairs. 50 \$\Omega\$ single-ended, 100 \$\Omega\$ differential, length matched. You’ve typically got two data lanes, a clock lane, so that’s six wires for the high speed pairs. Maybe some extra coplanar grounds. Plus 3.3V and ground, and two wires for I2C control, but those four are not so high speed. Personally I think the FFC sucks, and something like a USB3 or SATA connector might work nicely. |
