ADAFRUIT-AUDIO-FX-Alimentation

Alimenter la carte son

You won't be able to play audio while the board is connected to USB, so to actually trigger audio you'll need to unplug the USB cable and power it another way. There's many ways to power the Sound Board, you'll have to go with whatever it easiest for you.

Utiliser un PowerBank

This is by far the simplest way to power and doesn't even require any soldering! Simply connect the board micro USB to a USB power pack. Since there's no data lines on a battery pack, it wont try to start up as a USB key. Just connect with any microUSB cable. These are large but it will power the Sound board + amplifier for a looooong time

Alimentation avec amplificateur

The 2x2W amplifier version of the Sound Board is a pretty beefy 2x2W amplifier. If you are using 2 x 4 ohm speakers, that means you could be seeing as much as 2 Amp spikes of current. (In reality, assume spikes of 1A since audio isn't a DC load). Power with good charged batteries like AA's or even AAA's. For lipoly batteries, a 500mAh battery is minimal! Go for 1200mAh or more if you plan on playing it loud

Alimentation via VIn

You can use a AA or AAA battery pack and wire it up directly to the Vin an GND pins. We recommend 3xAA or 3xAAA alkaline or rechargeable as ideal. You can use 4xAA or 4xAAA but in that case, make sure you've got rechargeable batteries, as the higher voltage alkalines may be a bit much for the board.

	For most battery packs the red wire is the positive wire, connect that to Vin. The black wire is ground, connect that to GND.
	Solder both wires securely. You cannot just twist the wires into place!
	The nicer battery packs have switches, or you can just remove the batteries when not in use. If the green light is lit, it's powered up!

Utiliser un connecteur JST

If you don't want to solder wires directly, you can solder on a JST PH 2-pin connector to the back. We don't include this on the board because its a bit bulky and if the JST is in place you can snap a battery in or out easily. The connector is the same as the Vin/GND pins on the side so use one or the other!

All our ***LINK*** Lipoly batteries come with a JST, and our ***LINK*** 3xAAA on/off pack also does.

Or, ***LINK*** connect your custom battery with a JST cable

	Start by melting some solder onto one of the side pads of the JST footprint on the bottom
	Place the JST and solder that pad onto the connector to tack it in place
	Solder all four pads - two mechanicals on the side, and two power coming out the end.
	Plug in your battery and look for the green light!

Utiliser un Backpack

We designed a ***LINK*** Lipoly backpack for the Pro Trinket but you can also use it with the Sound Board! Use the extra long header included to solder it over the USB jack, it connects to Vin, GND and BUS

The Lipoly backpack lets you plug in a lipoly battery of any size and recharge it over the MicroUSB connector, so it's basically an all-in-one portable + rechargable system.

• • • link*** With the backpack, you can easily add an on/off switch, as well.
