  • LM1117 will be unstable with 10uF ceramic capacitor, use tantalum one

  • we don't want 5V Arduino here, 3.3V is better, so remove LDO and connect it to 3V3 rail like here https://github.com/sinara-hw/SATA_SFP

  • route MDIO lines to Arduino via 0R DNP resistors, we might want to configure the PHY without modifying the FPGA code

  • add missing sequencer circuit: Design checklist DIOT-Template#1
    Image

  • connect mezzanine PPS to EEM channel

  • MIC5219 is unstable with ceramic cap
