If possible use pin 2@J701 instead of pin 1@J702. It does provide a larger trace width to the 3.3V supply plane of the board and an additional ferrit to reduce noise.
By the way, the fuse at pin 4@702 is not assembled on "standard" boards, so don't use this pin to power the HAT.
You get NMEA messages on DEBUG TX as well. Use baud rate 921600.
To update the HAT you either own a programmer to flash directly or install the HAT on a Pi and do the update.
