“This, at last, is a really great GPS product for the Pi. First good thing is the SMA aerial connector. Many products have uFL connector which is way flimsy for something that moves and shakes. Second good thing is the ublox chip with supporting PC app for easy configuration. Build quality great too. Maybe packaging bit too good and that’s the only minus. Happily buy again. Every other GPS product goes in the bin…”
“Awesome little hat. Only loses one star as the instructions in the datasheet weren't up to date for 4b.
Note BAUD rate for serial link is 115200. Couldn't get /dev/ttys0 to work so had to disable bluetooth to use /dev/ttyAMA0.
Give the hat time to train a signal from a cold start (5-15 mins!) before expecting sensible data.”
“You may need to find a good tutorial: I note also that this only worked for me on 32 bit Raspberry PI OS.
I used https://www.tomvoboril.com/2021/06/gps-and-raspberry-pi-stratum-1-server.html and 2022-04-04-raspios-bullseye-armhf-lite.img.xz
The hat seems to be very well engineered and well supported - it's particularly good in that the supercaps mean no changing batteries. It's sensitive and just works. I didn't use the stand-offs provided because I was using the GPS Hat case but the I/O extender is necessary.”
“I tried 1.5 days at full time to get a signal from this GPS on the raspberry pi with NO SUCCESS.
I googled for hours and hours without success. The short documentation of the supplier is obviously wrong. Since I bought the special case to fit this GPS and the RPi, this is also a lost of money. Please stop selling this GPS and case !!! I can just throw them away.
PS: too few information from the provider and from Internet. -> BAD BUY”
