LuckFox Pico Pro Max: which converter cable for an Arducam 16MP?

[brainstorm]

I was looking at the Luckfox Pico Pro Max schematic and I noticed an unusual 20P camera connector:

Normally it's either 15-pin or 22-pin and there are convenient cables to adjust pitch and smaller boards:

I.e, Raspberry Pi Zero 2W has a 22 pin connector like so:

Are you planning to sell those custom FFC 0.5mm 20P adapter cables for other cameras other than the "SC3336 3MP Camera Module (B)" which uses this one that seems to be incompatible with i.e any of those Arducam cameras?

I'm thinking on manufacturing one myself but before I do that, I wanted to check w/ you... @luckfox-eng33 ?

It would also be very nice to have a pico MAX "plus" with 4 mipi lanes, instead of two.

Would the arducam 16MP sensor work with two lanes only?

[luckfox-eng33]

RV1103 supports a maximum of 4M@30fps RV1106 supports a maximum of 5M@30fps In addition, other cameras may need to be debugged by themselves.

If it can do 5M@30fps, can it do 2M@60fps ? It's less pixel/s. It would be nice to have a camera with higher framerate.

[luckfox-eng33]

Theoretically it's possible, but it hasn't been tested

Would it be possible to make a pico compatible with raspberry PI cameras? and with a faster ISP? Its size makes it a perfect fit for a HD system broadcasting OTA from a drone but high framerate is required for low latency.

[luckfox-eng33]

If you need low latency, you may need to write a streaming program, but the RKIPC latency may exceed 1.5S

Hey unfortunately it's not going to be easily possible.

I mapped the pins between different connectors at https://plati.ma/wp-content/uploads/2024/04/Schematic_MIPI-CSI_2024-04-28.pdf and then drafted a list of what has what at https://github.com/platima/sbc-cameras/blob/main/readme.md

Luckfox is annoyingly unique in these messed up 22 pin MIPI CSI connectors -_- I am considering fabricating an adapter board for it though if anytone is interested? Would be a few bucks, depending on the quantity.

If it can do 5M@30fps, can it do 2M@60fps ? It's less pixel/s. It would be nice to have a camera with higher framerate.

Should work - it's just about the memory reserved (64MB by default in RV1106 I think) and the bitrate. 5M at 30fps is around 2.4Gbps (yuv422) which is about the max of MIPI CSI2 using 4-lanes from what I know. As long as you don't exceed this, and the ISP can handle it, then you should be fine.

Possibly, as it usually negotiates, but you'd be capped at about ~9fps if it does work.
