Are the CM4 Ethernet Sync pins (16 +18) accessible on the CM4 Router Board Mini?


That would be awesome, because a CM4 has hardware time stamping that enables time syncing (PTP / GPS + PPS) with nanosecond  accuracy!

BTW: There is a typo in the title of the page: Compute Model 4 IoT Router Broad Mini
