Take 4 pieces of wire, and solder them to the 4 “A & B” - holes. (or use some other
means of connecting 4 cables to the standard sized holes, one can buy all sorts of
standard sockets and pins etc.)
On the backside of the board you may find some strange plastic. This has no

and parts they do not want so get tinned is sealed with this stuff) Just peal it off
when you need the holes they seal.
