    • ChargerReg0x33 = 0xA8
    • Charger_CV = 4.15 V
    • Charger_CC = 512 mA
  • Component-level properties on AXP192 updated to match.
Success criteria
  • ✅ AXP192 PMIC added to schematic
  • ✅ All project-level PMIC properties configured
  • ✅ Matching properties applied on the AXP192 component
Next step Save and sync the project to finalize changes, then proceed with a schematic review (next stage in the flux-agentic-workflow).
