Construction

Note that from J1 to J6, two jumper leads have to
be mounted in the same hole.

TIP : In order to get nice straight wiring, without too
much folding and measuring, follow these hints:

Mount the lead on the PCB as it is.
Solder 1 end of the lead.
Then carefully pull on the free end of the lead

until it is straight.

Now solder the other end.

J1 (2 wires)

J2 (2 wires)
