just starting to put this together. Instructions say ‘[] jumper’ but it doesnt say which one (there are two on the board), or which holes to bridge (each one has 4 holes). am i missing something here?
There are 2 jumpers marked by plain “J” on the board. Those are near by IC2 and IC3.
J1 and J2 are screw connectors. See the connection diagram on page 13 of the manual.
