Most Important Missing Info (Add This)

  • VDD_IO (ball B12): supply for I/O bank; absolute range 1.7–3.6 V; default tied to 3.3 V; decouple with 0.1 µF + 10 µF close to pin; max surge current X mA.
  • RESET_N (ball A3): active-low reset input; internal 100 kΩ pull-up; require low pulse >= 10 ms for full reset; deassert only after all VDD rails stable for 2 ms.
