A non-working control board. I personally think it's just the single MLCC that broke off the corner near the capacitor (circled in red), but I make no guarantees of course. I would have attempted this fix, but by the time I noticed this missing MLCC we had already swapped the control board for a new one. I appologize, but because it's a salvage operation - I am not accepting returns on this item. The price is quite low because I am under the impression a new board costs around $200-300 The diagram provided is for reference - this may not fully match the board for sale. That board is potentially a newer revision/layout. Begode seems to flash firmware to their boards, but otherwise they aren't super different: hence why a new board may have a different layout.
