Board supply pins split into the main logic rail plus aux rails by real voltage (ESP32/XIAO VIN,5V -> aux_rail_5 at 5 V; 5V-Arduino 3.3V pin -> aux_rail_3v3; Pico VBUS/VSYS -> 5 V). An external 5 V supply wired to VIN used to read 3.3 V (ideal vcc_rail source clamped the whole net — customer isolated it with a voltmeter). Aux rails join positiveSourceNets and the relay nominal-voltage check; the voltmeter and hover overlay read them. Also: ratings entry for the 4-pin ssd1306-i2c-4pin (supply pin VCC) and a VCC alias on the 8-pin entry, so its power check works at all. |
