That's one of the reasons why I'd like a GM with PPS, nmea in. My other sensors accept it.
Another user referred me to this dev board, which is not open source, but cheap and precisely what I need. https://qulsar.com/Products/Embedded/MTE_P60_Prototyping_Board.html I don't need crazy precise timings tough. less than 300 micros is acceptable for now (Yeah I know that's a lot from most ptp users point of view) On Fri, Jul 19, 2019 at 9:54 AM shouldbe q931 <shouldbeq...@gmail.com> wrote: > > > On Thu, Jul 18, 2019 at 3:48 PM Maxime Lemonnier < > maxime.lemonn...@gmail.com> wrote: > >> Hi, >> >> I'm looking for an affordable, compact ptp-grandmaster, that could sync >> with an external GPS + PPS feed.
