After 2.5 weeks, received 03008-006 PCBs from DKRed. Board quality very good, no mistakes were made on my end or theirs. Silkscreen font kind of squiggly in places. Overall experience was positive, though very slow. They sent 2 extra boards (6 instead of 4). Should probably make the thru holes slightly larger next time. Soldered 7-segments and JST connectors to the PCB and tested some sample code to display digits. There is some software/hardware glitch that is interfering with the buzzer and LEDs. Also, had to hand-crimp the individual JST metal pins to each wire using needle-nose pliers, as the junky JST crimpers I purchased are terrible. I also prepared two additional boards to be shipped out to support the 03009 project.
