Alternative breakout board for cm level accuracy

GPS/GNSS Development Boards

Hi, Im wondering if someone can help me find this board. I purchased this in Australia and id like to buy directly from SparkFun. Does anyone know if they are still available?or if there is a suitable alternative. Ive seen the SparkFun Quadband GNSS RTK Breakout LG290P in a video online and wonder if it would be a suitable alternative. Im also looking for antenna options. I currently run the system on a raspberry pi 4

Low-cost magnetic GPS/GNSS antennas can be used but a 4” / 10cm metal disc is required to be placed under the antenna as a metal ground plane.

@YellowDog linked to the direct replacement board that you have now.

If you are interested in the LG290P, you can consider the PostCard as well, which would also replace the Rpi 4 (depending on what you have the Rpi doing).

There are lots of antenna options online. It really just depends on how much physical room you have.

  • For the F9P-05B, you will want L1/L2 at a minimum
  • For the LG290P, you will want L1/L2/L5 at a minimum.

This is the best performing antenna at Sparkfun:
