Work done
  • Updated project description with new goals and hashtags
  • Updated System Architecture property with I2S mic and BMX160 IMU
  • Added Bosch BMX160 9-axis IMU as U3 and configured its properties
  • Confirmed and configured ICS-43434 I2S microphone (U2)
  • Marked USB-C connector (J1) as power-only sink
  • Added project property wiring_status = "deferred"
Tasks remaining
  • Remove the BMI270 part (designator U3) from the schematic to complete the IMU replacement
Success criteria review
  • ❌ BMI270 replaced with BMX160 9-axis IMU (still present)
  • ✅ I2S microphone (ICS-43434) correctly integrated
  • ✅ USB-C connector configured as power-only sink
  • ✅ BOM flags and designators updated for U2, U3 (BMX160), and J1
Next step Remove the BMI270 from the schematic to finalize the IMU swap, then proceed to the Connectivity stage of the workflow to assign nets and connectors.
