I'm looking for a single-board computer with seemingly simple requirements:
- Gigabit ethernet port
- Ethernet port supports HW timestamping for PTP and NTP
- Low power usage
- Few GPIO pins
- The ethernet interface is not USB
I've searched for a while, but it's very annoying to search because HW timestamping and if the ethernet is connected to USB or not is rarely listed.
Maybe someone here knows any good devices?
