The move will see Hopper, who is from Boston, return to his home county of Lincolnshire.
Hopper has agreed a three-and-a-half-year deal.
Meanwhile, Cambridge United have signed young Ipswich Town midfielder Idris El Mizouni on loan until the end of the season.
The U's have also signed Barnsley striker Victor Adeboyejo on a loan deal until the end of the season.
