HELP - Need Controller Board Pinout

Just recently got myself a Dreamcast, and was doing the usual mods. I set out to replace the power LED, and somehow managed to rip out the copper pad to the anode. So I was wondering if anyone knew where the led hooks up on the ribbon cable connector, or somewhere else I can get 2.8v.

Thanks!

Uh, you ripped the copper trace PCB_master? :lol:

Download a Schematic for the board, and look for it.

 

If you are looking with the under side of the board facing up and the controller ports facing you.

The anode connects directly to the bottom right pin of the ribbon connector.


Hopefully ive explained that well enough as I do not have a camera to hand

This is extremely unhelpful. Schematic from where exactly? Sega didn't exactly release them.

You post far worst requests than this, so I wouldn't judge if I were you.

Edit:

Phone camera to the rescue.

 

Thanks Bad_Ad84. I will try this as soon as I scrounge up another LED as my parts bin is in storage

 

Don't be too hard on the guy, hes still in high school and is trying to play ball with those of us with many years experience that he'd like to garner from but prefers to piss on when it becomes clear to all he talks the talk but can't even crawl the crawl.

 

l_oliveira posted some Dreamcast schematics for the VA0 motherboard revision in this thread:-

Perhaps the "CONNECTORS" diagram will help?

 

Points I posted are a direct connection (rather than an alternate power source). He shouldnt need a schematic now.

I just happened to have an open dreamcast on my desk when I saw the thread, so I check it and posted.

 

The schematics didn't match the maple board connector from my Dreamcast at all, so perhaps mine is a different revision. But if it helps, here's a pinout for the ribbon cable connector at the maple board:

1 - LED anode (cathode goes to ground)
2 - From positive terminal of battery through R1
5,7,11,13,14,16 - Ground
17,18,19 - +5V
20 - Fan speed
3,4 - Port A pair (SDCKA,SDCKB)
6,8 - Port B pair
9,10 - Port C pair
12,15 - Port D pair

 

I found a red LED lying around. 100 ohm resistor in line because the LED gets really hot on 3.4v.

 

Excellent work ^_^

You should have just bridged the entire length of the resistor, so that the blue wire would not be needed ;-)

 

Wire thickness is fine, soldering job isnt so hot.

Also, do you browse for old threads or something? you tend to post in threads weeks later...?

 

Nah... Im just bored and sick in bed

 

Fair enough
