Hi, Does anyone know where to get the COMPLETE schematic of a chipKit MX7 (ormer MX7 Pro (former mx7ck))? Thanks in advance.

You can't get the complete schematic. The debugger is closed source and licensed from Microchip. On the schematic (https://reference.digilentinc.com/_media/chipkit_pro_mx7:chipkit_pro_mx7_sch.pdf) it would be on page 9, which is (oxymorinically) "intentionally left blank".

Do you know what IC12 is on the last page? Thx

Not sure what model it is (it's too small to have a number on my board), but it's basically a USB power switch with over-current detection (I think). Used for turning on and off VBUS when in host mode.
