Hi everyone
We’re trying to find out which IC is U11 on the X-carve Rev. G pcb. We damaged the board by handling the step motors connectors while these were powered. We managed to track down the damage to the U11 IC on the main PCB, but we’re having dificulty identifying which IC is this. Is there a schematic for this pcb available?
The IC has ‘AHA’ written on the top, here are some pictures of these.
Thank you so much!
Cheers, Luís Pereira.
In the event that you are not able to identify the specific component Inventables does sell the entire board as a replacement here> X-Controller Main Board – Inventables, Inc.
Thank you.
Hopefully it won’t come to that.
Maybe a lpv521 opamp?
Someone here probably has a pdf of the Xcontroller schematic (not available on grabcad anymore).
If not, contact Inventables. They should be able to provide the schematic… Then post it here for the next guy.
That said, that’s an odd part to break.
We have the grabcad version, but it’s the Rev.E which did not have this IC, ours is Rev. G.
We’re enchanging emails with Inventables, but still no schematic or IC identification.
Hopefully they won’t make us buy the whole board. 
Inventables came through and send us main board.
Thank you so much!
Go Inventables!
