Manufacturing specs

Designed for JLC7628 stackup.

Revision Notes

Missing silkscreen labels for debug headers and UART headers
Pogo pins not quite centered.
Pogo pins should export 4 parts, not 1.
Power regulator and ADC should be moved to underside of board to avoid potential mechanical conflicts.
Ethernet magnetics footprint is incorrect (too slim).
Should have some way to provide power for standalone debugging (USB?)
I2C should have DNP pullup resistor footprints
Reset and/or power button would be nice
Pads on DDR connector could be thinned slightly
