It looks like the standard int8 version of MoveNet on TFHub is about 2.7MB in size:

This is probably too large for most embedded boards to store. I would also guess that the latency would be very high, since it’s designed for mobile phone CPUs. I would look into whether you can use a Raspberry Pi instead, if possible.
