User Instruction Book
The LED speaker has two main functionalities
1. Power Amplified Speaker
2. I2C LED Driver
Power Amplified Speaker
Power is provided (for both functions) via the rpi gpio pins (labelled on pcb). Once 5V power
is provided, audio signal from the 3.5mm audio jack is amplified and transmitted.
I2C LED Driver
Power is provided (for both functions) via the rpi gpio pins (labelled on pcb). Once 5V power
is provided, I2C data drives the rgb LEDs, as specified by the PCA9685 datasheet.
