You can buy an IMX477 board with CSI output and a CSI->USB board, ~$100 combined.
Not quite a fully assembled solution but all you have to do is screw the two boards together with a few standoffs.

The IMX477/R sensor supports Full (16:9) Binning 1080P @ 2028(H) × 1128(V) with 240hz/fps availability in a drive mode. However, no IMX477/R package I've ever found - including those from Arducam - support a CSI->USB board or similar that can drive this mode, only allowing 100 FPS maximum on most packages. (ex: https://www.uctronics.com/arducam-high-quality-complete-usb-...)
I am looking to buy a product involving the IMX477/R sensor that can drive this mode or similar 240 FPS modes, but cannot find it for the life of me despite the datasheet openly supporting this drive mode.
Image sensors are really just high speed ADC clocking out data, whether the data is useful or not is up to the viewer. What I’m getting at is forget FPS and think data rates.
So, you need a processor that is that can handle that data rate. The napkin math says 2K@240FPS has the same data rate as 4K@60FPS. All you need is a processor or module that can handle it and you’re golden. There are demos of the RPI pushing 1000fps (at a significant lower resolution) but you get the point.
Off the top of my head, NVIDIA jetson, imx8m mini plus, the latest allwinner V series, and a whole host of unobtainable in less than 10k qty parts all supported this. The rest is up to you.
Also, RPi is out even with 4 lanes because the CSI input doesn’t support the speed required on each lane.
Any idea where to start? I am proficient enough in scripting/coding to pick up a new platform like the Jetson/Nvidia products, but no idea where to find the correct sensor+board package to actually give me the data rates I need.
Looking for 240fps/hz @ 720p in some form of greyscale, for the record.
