Brochage
The top and bottom pin sets are the same for the headphone and amplifier out version of the sound board, we just use the headphone version for the photos below

The Sound Board has a lot of pins, but we can group them into chunks, lets go through each kind of group in order to understand all the stuff you can do.

Alimentation
There's a couple power pins in the top. This is what you'll use to power the Sound Board in your project.
- Vin - This is the primary 'battery' power input pin. Power with 3-5.5 VDC
- GND - there's a couple ground pins but we suggest this one for power input. The others can be used for signal grounds
- BUS - this is the 5V that comes from the USB connector. We break this out in case you want to use it to say charge a LiPoly battery (See the Powering It page!)
- PB - this is the 'Power Button' pin, which we use for testing. Just leave it disconnected for use.
In general, you'll only want to power through the Vin and GND pins. The Vin input pin is polarity protected and can use 3V-5.5V DC input. If you want to use a larger voltage, you'll need another regulator that can bring the voltage down to 3-5V DC

Port Série
If you want to control the Sound Board over UART Serial, you can do so by using the TX, RX and UG pins.
- TX - this is the serial OUT from the board. 3.3V logic
- RX - this is the serial INTO the board. We add some level shifting so you can use 3-5V logic.
- UG - the UART/GPIO selector pin. Pulled high for default GPIO trigger mode. Tie to ground and reset the board for UART mode.

Ajuster le volume
These are two extra inputs that can be used to adjust the volume in GPIO trigger mode only. Connect buttons that go from each pin to ground, when the button is pressed, the volume will decrease or increase
The volume is not stored during power cycling or resets, so it will have to be re-applied after restarts.
