I am new to GPS and ready to purchase a GPS breakout. I am trying to decide between the GPS-RTK-SMA Breakout-ZED-F9P (Qwiic) and the GNSS-RTK Dead Reckoning Breakout. However, if these breakouts use the same UBlox module why don’t they have the same accuracy? Have I missed something? I am looking for 10-20mm accuracy.
Different modules. One is a ZED-F9P, the other is a ZED-F9K.
Thank you for helping me to understand the difference.
