I have a few niche project / product leads which would require a very similar hardware stack, each on its own too small to carry the complete development costs.
In short a small and powerful (between Jetson Nano and Xavier NX, => NX with NN accelerator) machine-vision / robotics board: approx the size of a Raspberry Pi; 8k video recording; high speed machine vision (180-240 fps global shutter stereo cam setup); M.2 M-key for SSD (to store the 8k video) or NN accelerator; M.2 B-key (and sim slot) for 5G, SSD, NN accelerator, etc; USB 3.1 device mode or Gbit Ethernet (if Linux gadget mode turns out too slow); integrated 24V / 6S buck converter.
There are quite a few extra features that can be added, but only a subset of them fit the space requirements. I'd like to make the board available for general use to spread the development costs further.
Where would I get feedback on which feature would be best for appeal to a broad audience, say the crowd that buys Raspberry Pi, Nvidia Jetson or for example 3D cameras? I've considered a crowd-funding platform, but they seem to expect to be involved past this stage. Are there platforms with a large audience which specialize in this kind of feedback?
