Bti Ml-1 94v-0 Motherboard Manual
My sister works at an appliance place and they were throwing out boxes of electronics so she grabbed them for me and one of these was in there. I've searched and searched but have come up empty handed. I was kind of hoping someone here could figure out what it is and possibly how to actually use it. It came with the board you see pictured and the LCD attached to it and from what I can tell its got an ARM CPU, some memory, and there's gotta be an LCD controller somewhere on there also.
I would love to be able to put power to this thing and see if I get some sort of boot process going on. Any input would be greatly appreciated.

Holymoly - do control the size of your images. You may not get many responses 'cause this is hard to download / read. My guess - it's from a Whirlpool gold line refrigerator. If you are having fun, that's fine.

But if you need to build a touch screen LCD there are better ways to start. Try looking at sprakfun.com for starters. Guessing, these things are usually OEM'ed from Pacific rim outfits. So getting enough background to hack the thing is iffy.
On top of that, it appears difficult to second guess the connectors on an constituent appliance module. Or, to say it another way, it is easier to figure out what connectors / switches do what when they are designed to interface with a person (as opposed to the rest of the appliance). Maybe, just maybe, your sister can get a hold of the field service manual, and maybe there might be a schematic in there for the connections. It would be very doubtful there would be any information in such a document regarding the internal workings of this board though.good luck Posts: 1454 Joined: February 3rd, 2011, 6:10 pm. I have no intentions of making a touchscreen lcd, I dont really know where that came from. Thank you for your input though.
Oh, sorry - I just assumed you knew what you (probably) have. Let's back up a bit: You appear to have a resistive touch screen LCD display (assumed because of the flat finish screen appearance & the metal bezel around the edges) -and- a control board which uses the LCD to display information. The comment about a refrigerator was pure speculation based on 'that's the only Whirlpool appliance that I know of with a touch screen LCD'. Posts: 1454 Joined: February 3rd, 2011, 6:10 pm. Power supply: If this board came out of an appliance, I doubt there is an off-board 3V or 5V (common logic voltages) supply to be found else where in the appliance. So I doubt you will find a pin on the edge of the board that will power the chips directly. Think there was an inductor in one of the pictures.

So you might start there. I'm thinking you have a switcher (buck and / or boots) to contend with. As they would be much more efficient than, say, a 7805. If that was what you were looking for.
Is LCD back light the only indication of activity: Also, don't expect the screen to work even if you find the 3V or 5V rail. The back light might be a high voltage CFT. And w/o that you may not notice any difference between an operational board and a broken one. Fighting the right battle: Again, the problem w/ripping a board out of a device that has a lot of other things going on is that it makes it very difficult to guess at the purpose of the connectors / switches. Also, unless you received this board in a static bag looking brand new - it is probably a failed assembly.
There are many many similar devices out there (LCD displays) that are both working and can be hacked for less then a few dozen dollars. Picture frames come to mind. Posts: 1454 Joined: February 3rd, 2011, 6:10 pm.
