Added STM32F429ZIT6 which I used for development and will be using for the bard that is created in this pcb. I most likely will be using the pcb assembly services of something like JLCPCB because I probably will be using parts that are too small to be hand soldered
PID is now implemented and works as intended, the solid state relay needed a much slower carrier frequency for the PWM signal so the prescaller was set to 7. PID tuning is what needs to happen next.
