The tiny gps works when you get the right protocol. It didn't work on ubloks. Mine worked on nmea.

A good GPS module for it's size and weight. ublox Protocol on Betaflight 4.2.x gets about 10 satellites, on Bf 3.x only NMEA works, but up to 20+ satellites - see: https://www.youtube.com/watch?v=ywcoOz8robY and this module can be modded to 1.5 g by replacing the ceramic antenna with a simple dipole antenna - for pico and nano long range builds.
