It's all GPL code for the kernel, so there's no secret to it. I forget what kernel version the roboRio is running this year but it has to be one of these branches: https://github.com/ni/linux/tree/nilrt_pub/16.0/4.1

I think it's the 4.1 one but not sure. It's do-able, but tossing a pi in the mix and using NetworkTables to toss relevant vision data back to the roboRio sounds less risky.

Just my two cents.

The hole spacing is completely arbitrary and just copied what was already drilled into the frame. I'm working on a V2 with more mounting options as we plan to replace our Axis IP cameras with them.

They're not UVC based cameras so they need special drivers in the Linux kernel. I'm not sure if you can add modules on the Roborio, but in theory it would be possible to get it working with the kernel source and a crosscompiler.
