Work done
  • AXP192 PMIC is now present in the schematic.
  • Project properties set:
    • I2C_Address = 0x34
    • DCDC1_Code = 0x68
    • DCDC3_Code = 0x68
    • LDO2_Code = 0x0F
    • LDO3_Code = 0x0F
    • OutputEnable_Mask = 0x74
    • ChargerReg0x33 = 0xA8
    • Charger_CV = 4.15 V
    • Charger_CC = 512 mA

    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
