Revision Notes

Revision A

  • 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
  • VREF is floating on ADCs
  • led is on same FPGA pin as ADC1 refclk (U16)
  • Need to figure out the pin length for mounting the board directly to preprocessor
