Fitting the I/O piggybacks onto the main board
SYNNER-VF main board showing piggyback fixing holes and sockets
The I/O piggybacks plug onto the main board such that main board plugs PL6, PL5, PL12 and
PL4, PL3, PL11 align with piggyback sockets SK2, SK3, SK1. With the component side of the
module top-most, align the piggyback sockets carefully with the plugs and push firmly. Insert
the plastic rivets supplied with the fitting kit through the main board (holes ‘A’) from the
underside so they protrude through the piggyback board, then push the rivet peg firmly to
splay the end to lock the piggyback board in position.
Note: The position that the
piggyback is fitted determines the function of the rear module connectors
.
