## Wat
|
||
|
|
|
||
|
|
This pcb is an audio multiplexer, meaning it can switch three analog inputs into one analog output.
|
||
|
|
|
||
|
|
## Why
|
||
|
|
|
||
|
|
Sometimes you just need more inputs. And this is how you do it.
|
||
|
|
|
||
|
|
## How
|
||
|
|
|
||
|
|
The BD3491 does all the audio switching. It combines one 6 input switch and an equalizer into a simple package.
|
||
|
|
The STM32 configures the BD3491 to switch to the specified inputs based on pressed buttons or software control.
