Speaker
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.

    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.
