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.
Let me know if you need any modifications or further details!

    Speaker Shield

    Speaker Shield thumbnail
    A simple audio amplifier shield for the Arduino Uno R3. All through-hole components.
    #shield #arduino #lm386
    Usage
    The output connector is male molex (shrouded), good for cheap laptop speakers like this one: aliexpress.com/item/1005006144805292.html
    Don't use a speaker under 4ohms.
    Make sure the arduino is given 5V input.
    The volume is controlled by a 10k pot.
