VDDRF Power Flag Fix

A

adrian95

Please fix this, based from this flag issue:
LC76GABMD U4 part marks VDDRF as a power input, causing ERC Missing Power when left unconnected. Quectel LC76G Hardware Design V1.3 says VDDRF pin 14 is PO (power output), VDDRF=VCC, used for external RF components/active antenna and should be left N/C if…

This requires Agent mode to edit the part. I’ll change U4 pin 14 VDDRF from Power Input to Power Output, preserve its name/number, and verify the ERC Missing Power flag clears when the pin is left unconnected. Click the button to continue.
Continue in Agent Mode

I’ll correct VDDRF pin 14 to a power output, then re-run the relevant ERC check to confirm the false missing-power flag is gone.

flux

The pin type is now set to Flux’s canonical Power Out value. I’m checking the saved terminal metadata and the power-pin ERC result now.

Fixed VDDRF pin 14:
  • Pin Type: Power Out
  • Added description noting it may be left unconnected when unused
  • Verified no matching VDD_RF power-pin ERC issue remains
  • Filed an internal part-quality report for review of the source part data
