Vewlix Console I/O - Connect Brook fighting boards directly to your Vewlix.

Console IO draws a negligible amount, but the PSU also powers the audio amp. Your lighting is already close to 70W.

I knew I was getting close. I'm gonna get everything I can out of that out that thang! I don't use the factory amp. I have a very modified setup.

Ugh.... I can't for the life of me get this thing going.

I have the v4 powered via 12v PSU. When I connect the usb-b cable to the brook boards the red LEDs on the I/O will pulse once and then turn off. I think that is normal. Having said that, I am unable to do anything that involves the G Harness at that point (which I've double checked for correct wiring and connector seats). At the same time, the brook boards are detected in windows (multiple different boards tested) and the buttons that are hooked up to directly to the brook boards function as expected. Thinking it was a power consumption issue I disconnected the two LED arrays referenced earlier and tried again- same thing.

Anyone have any suggestions? I have a multimeter but not terriblly experienced using it. Honestly, if it weren't for the robust feature set, I would have already just switched to straight brook boards.

The latter, nearly all arcade psu’s require a minimum load that I doubt the control pcbs are providing. That will damage your psu over time, or it just won’t turn on in the first place. That’s why the other solutions for this all have a resistive load on the power pins

I am pretty sure I sent a note to the creator a while ago, but haven’t heard back. If anyone can get in touch, I’d buy these if that issue were solved. A large resistor and a heat sink would do it.

Do you know if they ever ended up fixing this on the Brook UFB to JAMMA? I just ordered one from Psychic Drive yesterday & wanna make sure they have fixed it in the time since.
