First, wow!  What a great community to be a part of.  Thanks in advance for everything you do.

 

I'm slowly building out my Virtual Pinball machine.

 

1)  I'm running the latest Visual Pinball X via the Baller Installer

2) I'm running Pinscape Pico on a RP2040 (Raspberry Pi) Controller board

3) I have 5 buttons hooked up and working (left/right flipper, coin, start, plunger)

4) I have a 3 screen system working (Back glass, Full DMD, and Playing field)

 

My next step is to add some simple DOF, I want to start with the flippers, and this is where my question(s) start:

 

I have my initial "shopping list" for DOF:
 

Power Supply - Mean Well LRS-350-24

24V

14.6A

350W

 

 

Drivers 

8 Channel MOSFET Trigger Switch Driver Module Optocoupler Isolated"

MUST HAVE

IRLZ44N (or IRLR7843 / AO3400 class MOSFETs)

low-side switching design

DC load rated (24V OK)

3.3V compatible input (Pinscape Pico requirement)

screw terminals

flyback diodes 

 

NICE TO HAVE

optional optocouplers (not required)

fuse protection per channel

separate logic/load power rails

 

 

 

Feedback

2 × Siemens 3RT1015 24V DC contactors

Siemens 3RT1015 with a 24V DC coil

 

 

Protection

Fuse block or inline fuses

 

 

Wiring

18 AWG stranded wire

 

 

This is the problem I need help with:

I'm confused about what to buy for the MOSFET board. I have found this one https://www.amazon.c...t/dp/B0GW8HVSNL
But when I double check with AI to see if it's correct, I get this feed back:

 

This is NOT a "pure MOSFET DOF performance board"

It is still:

PLC-style optocoupled driver design

sometimes transistor-based per channel (varies by revision)

not always a true low Rds(on) MOSFET stage like IRLZ44N boards

So:

What you get:

✔ reliable switching

✔ safe operation

✔ easy wiring

✔ works fine for flippers/contactors

What you don't get:

⚠ maximum electrical efficiency

⚠ "cleanest possible" high-end DOF architecture

⚠ guaranteed MOSFET quality consistency across revisions

 

 

Can someone please tell me if AI is correct (hard to trust AI), or can I use the MOSFET board I found, or is there a better choice someone knows?

 

Thanks!!
