hardware clock small size factor for RBPI3B+

[Stefan Parvu]

Hi,

Can anyone point me, list some models of RTC models which should work with 
latest production release of FreeBSD 12.0 ? Im looking to get for our RBPI3B+
boards a supported RTC which should work without rebuilding the kernel and
preferable have a small size like Rasclock [1]
