It should be supported since its also an arm processor that is generally compatible with what the pi’s use. I admit I am not very familiar with the Jetson Nano, what OS is it running? The problem is the auth package we have is precompiled for security reasons and as far as I am aware it is impossible to create a distribution of precompiled python code for multiple architectures and python versions…
We are working on a way internally to not even have to use precompiled code anymore for our auth scheme but the current work around is to just not even use it, see my discussion here: Bad Magic Number with Python 3.8 - #7 by Dom
You will have to use a device key to authenticate instead since the OTP is no longer included but it will allow you to use the hologram sdk.
