Electrical/GpioOvercurrent

A GPIO or output pin with a declared max_current carries more current than its rating in the DC model. The limit is in amperes in the part definition. This rule only evaluates a pin that is also an explicit, fixed-voltage provides terminal, so the output state and load current are known.

id: fixed_driver
category: offboard
placement: offboard
pins:
  - {num: 1, name: OUT, type: gpio, max_current: 0.01}
  - {num: 2, name: GND, type: ground}
provides:
  - {positive: OUT, negative: GND, voltage: 5}

Connecting a 100 Ω resistor across OUT and GND draws 50 mA, which exceeds the 10 mA limit. Increase the load resistance or use a suitable driver.

Ordinary GPIO pins without an explicit output state, unrated pins, and circuits whose DC analysis is unsupported are skipped. The check includes source and sink current, declared source voltage ranges, and resistor tolerances, and reports each rated pin separately. Diode circuits use endpoint estimates; Electrical/DcBoundsIncomplete warns when a passing check does not establish safety across the full range.
