Answered: power expander BOM

I killed a power expander this weekend on a non competition robot project. Looks like U1 is certainly dead and perhaps Q2. The PIC lives if I bypass U1, anyway, is there a BOM (or schematic) available for this product. If not could you give me the part numbers for U1 (which looks like a 3.3v LDO regulator) and Q1 so I can replace them as it’s probably not worth the cost to send back to VEX for repair.

Thanks.

Edit:

Well looks like it’s actually a 5V regulator, bypassed with a bench supply and everything works so only Q2 was destroyed, ordered a suitable replacement for $1.67 :slight_smile:

Confirmation of this would be appreciated.
