  • Datasheet
  • Customer feedback on setup (thanks to David Taylor): "You need to send a command to the board to enable Galileo. You could likely do that with a binary U-BLOX string with the 3.17 version of GPSD currently included in the RPi OS. It's much easier with GPSD 3.20 which you can get a back-port onto the Buster RPi OS, but if you need to support an RPi 1B you'll have to build GPSD from scratch as the processor has differences from the 3.20 back-port".


The breakout has the following dimensions: 22mmx22mmx1.6mm approximately.
