This is galvanically isolated mosfet driver (one drv per mosfet) that uses very fast inductive coupling IL610 chip. Output is connected with 3pin array to mosfet module. 3 instead of 2 to have more mechanical stability.
6pin socket is my standard to use ribbon cable socket that has GND, +12V, +5V, and a signal. Then you can connect everything to CPU or whatever, add modules in between to limit the pulse - so everything is plug and play.
