Ashot don’t know really well emlid product in that case
Hardware is the same for ublox m8t where T means it have time mark. Emlid already make timemark pin in their connector even if they are different between v1 and m+.
V1 have Intel Edison inside whereas m+ was built with emlid neutis n5 when Intel stop Edison production. They share the same operating system “yocto”. I used time mark on v1 and m+ and they work in the same way …
