Navspark rtk gps

im looking at the navspark rtk gps (PX1122R-EVB : PX1122R Multi-Band Quad-GNSS RTK Evaluation Board - NavSpark Store)

has anyone used this with the nano? is it easy or hard as hell to use on the nano?

I don’t have answer for GPS module, but you may try on use it with Linux host PC to confirm the status.
May other developers help to share experiences.
