Implement a servo part that uses the GPIO headers of a raspberry pi directly to control Mosfets on the flight computer board.
The part should be configurable for different behaviours such as pulse (turn on for a set amount of time) or manual on/off switching (It might also make sense to define this behaviour as a seperate part, this is up to experimetnation).
The main usecase for this MOSFET control would be the ignitors in the rocket that are being used to set of the motors or recovery charges
