It is interesting that the github does not mention that this FPGA chip is optimized for ML inference. Or is sold as such at least:

I am not versed enough in FPGA to know if this is just a marketing rebranding of common features (apparently a focus on LUTs and add-and-multiply operations) or if it is an actual edge.

Though, if that thing can do pattern recognition in images and draws 10 mA max, that's an interesting package for $24
