I've been checking over solderjoints, hoping to find a Q or U with a solderbridge, no luck.
Ah, I hadn't made the connection - I found your build guide before, it's what made me decide to order one. It's been useful for making A or B comparions for anything standing out. I've also been checking over the circuitboard hoping to find a Q or U inverted, but they're all following the soldermask guides. There's no breakout for and ground VCC_300 to easily probe?
