Hi,
I purchased a SwitchBlox (BB-SWB-E-1) and I’m trying to repair a damaged board.
I was powering it from a 6S battery when the board briefly contacted a nearby carbon fibre plate, causing a short circuit that damaged the input stage. Since it was 6S, this was a short-to-frame event, not overvoltage. C2 is visibly burnt, and Q1 (the input protection MOSFET near Vin) also appears to have failed.
The marking on Q1 is burnt and no longer legible, so I can’t identify the part to order a replacement. Could someone tell me the exact part number (manufacturer + MPN) for Q1? The part numbers for D8 and C2 would also be helpful, in case they need replacing too.
I’ve attached photos of the damaged area.
Th
anks!
