With the exception of a few outliers, all active components have been ordered. I have enough for 2 main boards, or enough for 1 board and then spares ;), and 3 displays. Since mouser isn't shipping until Tuesday, I'll finish up the passive component wrangling, need to calculate power ratings, and place a separate order tomorrow. Still a hefty chunk of change. I tried splitting up the components amongst 2 or maybe 3 suppliers, but I'd save maybe $10 in this low quantity.

Display boards are not yet complete in schematic capture, let alone board layout, though both have commenced. I'm iffy about the crossover connections on the mDP cables since I'm not sure if the + lane swaps with the + lane or neg lane. I'm assuming the former and have wired accordingly. I can test conductivity with the receptacles when they arrive. The display board design accounts for a breakout board for the mDP so there is a little extra design complexity, though I feel I've sorted it. I'll place this batch of boards through Advance Circuits as there are fewer things to overlook and I need 3x the amount. Time for sleep, then work.
