Duo2 S.E. - 3.3 or 5v?

[lufcfan]

Is the Duo2 SE a 3.3v or 5v chip? I'm installing one in a V7 and I would prefer to take power from the Matrix Infinity V7 power point if the chip uses a 3.3v power source (quicker to solder to a pad afterall). If it's 5v, then I'll just have to take it from where the diagrams say. Thanks a lot... LUFCfan

Check the points with a multimeter.

[lufcfan]

Is there a definative answer to this, because I can't check the points atm... (Not at home).

[lufcfan]

So, does anyone have any Alt. points for power on a V7 board for a Duo2 SE then? Thanks a lot... LUFCfan

Have you considered searching Shadowknights installs? He tends to use his own points. Maybe he used a different power point in one of them.

think its a 3.3v power cable on the duos as most new chips use this, the only chip i have ever heard of using a 5v supply is the magic 3 (yuck) any way if the chip is under powered then the game will not boot so you will know "she needs more power captin"
hope this helps

Thanks a lot. I've had a few messages saying they're 5v = so any points for 5v power on a V7? Thanks a lot in advance...

I use the PS4 fuse m8, right next the point on the diagram but mucho bigger.

[lufcfan]

OK - I used the one from the Magic III diagram. However, I now boot up to discover only originals work and no backup games work whatsoever. I can't tell what I've done wrong - I have no bridges and everything seems OK - any wires I need to check guys? I'm gonna check the BIOS ones now - anymore?..

Me and Duo2s never get on. Matrix Infinitys are great everytime, but Duos - nah - they never work for me

The B wire is a common mistake m8, you'd be amazed how many peeps (including me) fit it to the wrong point & also make sure you fit the Z. Daft as it sounds these lil things..........................

[lufcfan]

They seem to be in the right places m8. I'm thinking it's easier to completely rip out and restart...

[Hull_chipper]

Defo m8, you spend hours searching for a fault but 40 mins to reinstall!

[lufcfan]

OK - I don't see what i've done wrong. I have replaced EVERY wire (again) and still absolutely nothing. Could it be a chip problem???

[Hull_chipper]

Of course you can have a bad chip m8 but lots of peeps suspect the chip, try fitting it in another version & if you get the same response return it to your supplier (assumin you used a reputable source of course).

normaly the screen goes black and nothing happends when you try to boot a back up game only ever had this happen to me once it was a dead duo put a diffrent duo in and the system worked 100%
