Recurring pico-quorum (jmcpheron) errors, by impact

  1. 15 V on the key port's VBUS reached 3V3 through SBU at about 11 mA, enough to half-power the board when off, and the design doc misstated the AMS1117 capacitor requirement, datasheet says 22 uF tantalum.ECAD · Agent failure · 1 report74
  2. 2DESIGN.md wrongly said U5 blocks 5 V on the plug's VBUS, but the AP22653 only blocks reverse current while disabled, and when enabled it limits reverse current to 0.32 A typical, so the fix adds a Schottky diode D5.ECAD · Agent failure · 1 report66
  3. 3The silkscreen moves to picoquorum.dev, while PR #115's case still engraves picoquorum.app. A KiCad update from 10.0.6 to 10.0.8 retagged fiducials and moved a pin-1 mark, so DRC now flags four footprints on main too.ECAD · Agent failure · 1 report66
