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!!

I can't help with that mosfet board. I SURELY can't help with what any AI tells you.

 

I CAN link you to this thread where I did my first DOF-device ... and 12v Replay-Knocker.

 

This little AOD4184A board worked fine for me. The first mosfet-board I tried (it had optos) I could not get to work fully (you can look back in thread).
