power on this board?

that board has a 4 pin molex connector.

those 4 pin molex connectors from a computer PSU carry 5V

That small sized 50pin connector on there I am pretty sure sends power out
on some of those pins. Assume it does.

What I want to know from you electronics experts, is this..

and perhaps it's not a basic question.. and this isn't the right group?

there may just be one possibility if you're expert enough as I hope, but i'll
assume there are two possibilities. either the board sends out 5v down that
50pin connector(i.e. doesn't convert any voltages), or it sends out 3.3v(i.e.
it does convert voltages) I do not know which.

What i'd like to know, is can you looking at that board, those components on
it, tell me for sure one way or the other.. if
a)this board is converting voltages
b)this board is not converting voltages.

and what you're looking at, what electronic component it is.

thanks

What's the part number? It looks like there is a regulator (that's the
black thing between the two orange things (capacitors)) but one can't
tell from the picture what the output is.

Looks like a parallel ATA to compact flash adapter. My guess is that it
converts +5VDC to +3.3VDC for compact flash that is not 5 volt tolerant.
Looks like a SOT223 package. Could be similar to:

I guess just from looking at a picture, you can be sure there's a voltage regular
on it but even if you see a voltage regulator, it may be conditional, it may
not be conditional..

And just looking at a pic it's not possible to tell, is that right?

I suppose in the case of the pic I posted, it's fine for 3.3V HDDS, it won't
feed them 5V. But a 5V hard drive, if there are any 5V HDDS with that 50pin
IDE interface, then one can't know if it'd feed them 5V or just 3.3V

If I put the molex connector in it, would I be able to test if it is conditional
and see either voltage coming out, without plugging a hard drive in?

It's not for a hard drive, it's for compact flash. It allows you to use a
compact flash as a disk drive. You should be able to check the voltage
output using a DMM. What are the markings on the four pin SOT device?

PATA connectors are 40 pins for 3.5" drives, and 44 pins for 2.5" drives.
However, if you count the missing pins on a 2.5" drive it is 50 pins
total. The last four are usually used for setting the master/slave/CS
config. The problem with the adapter in that picture is that it's the
wrong gender to interface with a 2.5" drive. I've no idea what that would
plug into, as most motherboards that I've seen have male connectors, not
female.

here's a 2.5" pinout. 40+4 for power + 4 more if you count the 2 pairs of
master/slave pins. 48pins in total.

I know 2.5" and 3.5" have pins on the back.

I have in my hand a 1.8" HDD.. it is female on the back, and 50 pin.

Toshiba MK6006GAH

so it'd plug into the adaptor.

In the laptop I saw it in it had a little cable which was male on the end that
went into the hdd. the other end of the cable was just stuck in with no connector.

you write
"It's not for a hard drive, it's for compact flash. It allows you to use a
compact flash as a disk drive. You should be able to check the voltage
output using a DMM. What are the markings on the four pin SOT device?"


i'm wondering if this type of 50pin CF and the 50pin IDE connector are the
same..

though the device itself would be different 'cos the hdd is the still famous
common spinning type, not ssd.

I'm not an electronics geek.

What is the 4 pin SOT device?

I plan on getting some adaptors and testing the voltage before I try plugging
my hdd in.
 
If it's 50 pins, it could be a SCSI adaptor of some type.
