Do you happen to know what the board name returned from os.uname().machine is for the PyBadge LC? In the boards directory, there's only pybadge and not pybadge_lc or similar.

Oh, interesting! I don't know.

I guess the only thing I'd suggest is putting the try/except as nested as possible.

Ok cool, I wasn't aware you could nest them.

Sorry, that's not what I meant. The RuntimeError try/except should be as nested as possible so that it only catches exceptions from board.I2C(). IE, it should be inside the if. Having it at this outer level risks catching other exceptions and is generally harder to read than proactive code.

In general, exceptions shouldn't be caught when the code can be written to know ahead of time. For example, the second try/catch could be replaced by an i2c scan to determine the address prior to calling the device constructor. Doing so would deduplicate the call to the constructor and clarify things.

Ok, maybe this is closer to what you meant.
