This diagram outlines the power and signal flow:
  • The USB-C Port provides power for charging.
  • The Charging Circuit manages the power conversion and charging of the Battery.
  • The Battery supplies power through a Power Management Unit (PMU).
  • The PMU feeds both the Bluetooth Module (for audio streaming) and the Audio Amplifier (LM386).
  • The Bluetooth Module sends the audio signal to the amplifier, which then drives the Speaker.
