I finished the V1 PCB design over the Easter long weekend and ordered the PCB from JLCPCB.com.
I also ordered the components from Mouser and AliExpress.
A few days later, the PCBs were in my hands! Very impressed by the low cost and super-fast turnaround of JLCPCB.
The only immediately visible issue is that I didn't pay attention to the silkscreen Gerber export and it's missing the values layers and some outlines & text. But otherwise everything seems correct! I'm very happy with them.
I'll put up the V1 schematic and board Eagle files shortly.
