Hi I’m from a software background so I’m sorry for the newbie questions hardware wise.
I would like to use the components which make up:
2 x boost control solenoids:
MAC boost control solenoids are typically 12V DC, 5.4W devices rated for up to 120 PSI, and use a 2-wire configuration. They are driven by pulse-width modulation (PWM) and generally recommend a PWM frequency of 10–20 Hz, though some sources suggest a range up to 30 Hz or even 40 Hz, depending on the specific model and ECU. The most common model is the 35A-AAA-DDBA-1BA, which has a power consumption of 0.45A at 12V.
Key Specifications
Voltage: 12V DC
Power Consumption: 5.4W (approximately 0.45 Amps @ 12V)
Max Pressure: 120 PSI
Port Configuration: Typically 3-port, but 4-port versions also exist
Wiring: 2-wire configuration
Recommended PWM Frequency: 10-20 Hz, although the operating range can extend up to 30-40 Hz depending on the application and ECU settings.
PWM Control for MAC Solenoids
Frequency:
The solenoid is activated by turning its coil on and off at a high frequency, which is controlled by the ECU.
Duty Cycle:
The percentage of time the solenoid is on within that frequency is called the duty cycle.
ECU Settings:
A duty cycle table in the ECU, which may be based on throttle position and RPM, selects the solenoid's duty cycle to achieve a desired boost lev
And then for each of the 2 pwm style modules (ZK-PP2) almost pinch the components from 2 of these on a single PCB and have the arduino control pwm
So 2 PWM controllers one for each solenoid.
I’m trying to work out what mosfet setup I might need to go from the arduino to the boost controller
I was going to grab a ubec style setup to take 12v and convert to 5v
I am assuming this is for a MAC diesel tractor. Are these solenoids High or Low side switched.

Low side switched
Low will close the solenoid with 0% duty and open the solenoid with 100% duty. High will close the solenoid with 100% duty and open the solenoid with 0% duty. (Default = Low)
