This board supports up to four BIP373 ignition drivers which are not included in order to keep your cost down since most of you won't need them for running your stock setup. If your application does require internal ignition drivers (again, most do not) you can add BIP373 ignition drivers to your kit.  We offer a DIYPNP BIP373 mod-kit which includes the BIP373, Heatsink, and mounting hardware here.
