The next level in tiny Arduino compatible boards: the digispark pro. A balanced compromise in size vs features vs price.
In a standard setup there can only be one SSL-server per IP:port. But if you have a wildcard certificate for eg *.domain.net you can have separate servers configured for appropriate hosts below domain.net like www.domain.net + test.domain.net + … Read Wikipedia on Name-Based VirtualHosts and SSL.
