Introduction
The SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 stereo, filter-free class-D audio power amplifier. Its efficient class-D operation also means low heat and long battery life when driving 4Ω speakers at up to 2.8W in stereo, and 8Ω speakers at up to 1.7W in stereo. It won't shake a stadium but it will provide plenty of volume for your audio projects.

Required Materials
To follow along with this tutorial, you will need the following materials at a minimum. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
Minimum Parts
At a minimum, you will need a cable and differential speaker with the Qwiic Speaker Amp. You will also need a power supply and some wires. This is assuming that you have a media player (i.e. smartphone, computer, or portable digital player) with a TRS audio output and the speakers have wires connected to the terminal.

Connecting with an Arduino
For users that want to configure the TPA2016D2 with the Arduino Library, you will need an Arduino microcontroller. We'll be using the RedBoard Plus with the ATmega328P. Make sure to add two speakers to your cart if you decide to have stereo output.

Accessories
There are many ways to connect to the Qwiic Speaker Amp. Below are a few accessories that you could use.
Speakers
Below are a few speakers from the catalog that you could use as an output. You will want to choose differential speakers like the following listed below (not to be confused by the piezo buzzers). Note that some speakers may perform better than others at certain frequencies while others operate around a certain frequency range. Make sure to check out the speaker's datasheet when choosing a speaker.

Depending on the connection, you will need jumper wire for the power, audio input, and/or speaker output. Below are a few wires from the catalog. Note that other wire might be too thick and may not fit the screw terminals. If the terminals on the speaker are big enough, you could also use spade quick disconnects as well.

Power
To power the board, you could use a separate power supply for the Qwiic Audio Amp. For installations, you could use a 5V wall wart and a barrel jack adapter. For portable applications, you could use a LiPo battery and boost converter for a constant voltage input.

Tools
To secure the wires in the screw terminals, you will need the pocket screwdriver set. Note that some screwdriver flat heads might be too large to drive the screws. The pocket screwdriver set includes a drive bit that is compatible with the screw terminals that are soldered on the Qwiic Speaker Amp. There is also another drive bit that you could use to secure wire to the barrel jack adapter as well.
