M1 - fan motor, controlled by IRL540 Logic level transitor. I'm decided whether the fan will be controlled using pwm.
M2 - motor used to control door. Controlled by mosfet driver TC4420.
D1 - the purpose of this diode is to prevent reverse polarity.
SW1, SW2 - magnetic sensors used to check the door position.
I am wondering about MCU power supply filtration, because during my tests MCU was powered either by JLink or USB, but now I need to take care about power supply on my own. Does the blue pil already has some internal capacitors and adding addional ones won't be nescessery or should I add them?
