Hi @jimalex
Thank you for your support.
I wrote that warning to be on the safe-side. You are probably OK, but this would require you to “test and see”. My recommendation, however, is not to use the GPS antenna. If you have an Internet connection, then you will get the same timing quality using the standard mode of operation (NTP) as you would with GPS. If you are interested you can read more about why here.
Whether or not this hat can be used will depend on which pins it requires. Note that nothing can be stacked on top of the Raspberry Shake and the Raspberry Shake needs access to these pins. Tx/Rx, for example, cannot be shared. But again, this would be “test and see”.
We are always curious to learn what technologies work harmoniously or not with our system. So please report back sharing the results of your experiments!
Yours, branden
