hardware clock small size factor for RBPI3B+

[Stefan Parvu]

To be honest I have now 3 rasclocks and 3 more coming (ver 4.2). I would love
to make these working first and test them on RBPI3B+ and maybe RBPI4 later.

But if you have some links Amazon or other shops share pls to see what other
people are using. 

Cheers,

Stefan Parvu
