1/4-inch spade lugs, with screw terminals for the siren and strobe. This
allows for easy packaging and quick board swaps.
+The photo above is of an early prototype, the design has changed slightly
+since then. It is still possible to package the board as shown in a Hammond
+polycarbonate box, but metal ammo boxes are a credible alternative. The two
+switches are for power on/off and safe/arm. The two cables are for DC power
+in and igniter leads out.
