Hello Aerendraca, thank you very much for the response!
I am aware that this project might not be feasible, but i sure am willing to try!
I have always been a tinkerer of sorts, and i face this not only as a way of getting a new "gadget" in the house, but also as a learning experience. I'll take whatever i can get out of this experience gratefully.
So, first of all, here is the project donor:
Here is the pen that came with it:
As i said previously, it is an Asus EP121 Slate. It was purchased as a refurbished unit in April 2013, and worked well until the end of this November until it died.
Using the card to snap out the cover
Here it is - take notice that the temp sensor cable was detached from the board, as it is glued on to the back cover.
If someone comes across this and is curious on how to remove the parts, i marked the screws that need to come off:
First, to remove the battery, you need to remove the screws (red circles) and the battery connector (blue rectangle):
One of the screws is hidden under the battery connector and a couple other cables:
Next, you need to remove the fans (green circles) and heatsink (blue circles). Be careful with the heatsink as it will be also have thermal paste between it and the chips.
After you have removed the fan/heatsink assembly, you can remove the motherboard.
Unscrew all the screws located on the red circles, and then remove the 2 ribbon cables to the left (yellow rectangles), the connectors for the digitizer and touch panel (red rectangles, right side) and finally the connector for the speakers (red rectangle, top left).
At this point you should see something very similar to the link Aerendraca posted above; basically, the display+touch+digitizer assembly.
Now we can see this:
On this unit, it has as you said Aerendraca, a Hydis HV121WX6-12 Display.
The digitizer, part nr. SU5E-12w34AU-01X
And the touch controller board, part nr. FTU2-12W11U-01X
Now, here is the digitizer controller panel in detail:
It is a 14 pin connector.
On this unit, it appears that the pins being used are 1,2,3 and 12,13 and 14 (as the picture of the cable below shows).
I will also leave a more detailed picture of the touch controller board, if anyone finds any use for it.
Now, my primary objective with this unit would be to get the digitizer working. Touch is not important, but it would be good if i was able to get it to work as well.
Once again, thanks Aerendraca for your kind words! Hope these pictures can help get this project going, and also help someone else that might have the same idea!
