BMP180 Floating Pin Fix

I’m blocked because there are no available ACUs, so I can’t inspect the PCB or run AI auto-layout/routing tools right now.
What has been accomplished so far:
  • In the previous attempt, the PCB was identified as still needing layout work.
  • No new placement or routing changes were applied after ACUs became unavailable.
What remains:
  • Inspect the latest PCB state.
  • Decide whether placement, routing, or both are needed.
  • Run auto-layout/auto-routing and verify DRC results.
Once ACUs are available again, re-run this request and I can execute it automatically.
I’m still blocked because there are no available ACUs, so I can’t inspect the PCB state or run auto-layout/routing tools.
What has been accomplished so far:
  • Earlier, the PCB was found to still need layout work.
  • No additional placement or routing changes have been applied since ACUs became unavailable.
What remains:
  • Inspect the board for unplaced/misplaced parts and airwires.
  • Determine whether placement, routing, or both are needed.
  • Apply auto-layout/auto-routing and verify the result.
Please restore/add ACUs, then send this request again and I can proceed automatically.
Inspect J1 first
Check J1 placement
Run ERC/DRC later

    Template for Raspberry Pi 4 Shield. Include an official pinout so you will always know Raspberry Pi names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Raspberry Pi itself along with the board outline on the silkscreen. #RaspberryPi #Raspberry #Pi #RPi #Shield #template #project #project-template #raspberry
