How to Connect 8-Ohm Speaker to Raspberry Pi

In conjunction with Broadcom, the Raspberry Pi Foundation in the United Kingdom produced a series of small single-board computers (SBCs) that are now available for purchase. This initiative, called Raspberry Pi, was established to encourage the teaching of basic computer engineering in institutions and underserved areas of the world. The first model has proved to be more popular than anticipated, with sales occurring outside of its targeted market for robotic applications and automation, as well as within it. There are numerous applications for it in various fields.

Simply connect any 4 to 8-ohm speakers with a maximum power of 3 watts, execute our installation script on any Raspberry Pi, reboot, and you’re ready to go. Each order includes a completely completed PCB that includes a 2×20 header as well as two terminal blocks. A small amount of soldering is necessary to connect the header to the PCB so that it may be plugged into the Raspberry Pi.

This article has detailed information on how to connect an 8-ohm speaker to a raspberry pi. You will also find answers to some of the frequently asked questions. In addition, you will find some guidelines on what to take caution on and what to replace where need be.

Connecting an 8-ohm speaker to raspberry pi

how to connect 8 ohm speaker to raspberry pi

With this Bonnet, you can take advantage of the I2S digital sound technology, which produces extraordinarily clear audio. There is no static noise that may be heard through the headphone jack since the digital data is routed directly to the amplifier rather than through the computer’s speakers. It is also really simple to get things started. Just hook up any 4 to 8-ohm speakers with a maximum output power of 3 watts to your Raspberry Pi, run our installer script on your Pi, and you’re good to go.

One full printed circuit board (PCB) with a 2×20 header and two terminal blocks is included with every order. For the header to be connected to the PCB and inserted into the Raspberry Pi, a minimal amount of soldering is required. In the following step, you can either insert one of our included speaker sets straight into the JST port in the middle of solder in a wiring harness before attaching a different speaker of your choosing to it.

Don’t forget to use a reliable, strong 5v supply – particularly if you’re using the 3W 4-ohm speakers – to ensure that everything works well.

Step 1; A 2×20 female header should be placed so that the connector is at the bottom. Some tape can be applied to the back of the piece to make it simpler to hold in place. Use whatever you have on hand, including tacky clay.

Step 2; when making an electrical connection, keep in mind that all of the pins are securely soldered together. Solder the very first row of headers together using a soldering gun to ensure that they are completely sealed. Flipping it around will completely solder the opposite row. Following the completion of the head strips, you will be completed with the project.

Step 3; Preliminary visual examination of your solder joints should be performed before moving on to the next stage. After that, we’ll solder in the two 3.5mm terminal blocks that will be used to link the Speaker Bonnet and speakers to the circuit board.

Step 4; Make certain that the open parts of the adapters are facing outward to join wires as conveniently as possible. If you want to make it simpler to keep the two header pieces in place, you can tape them together to make it easier to hold them in place. Tacky clay and other materials that you have on hand can be used.

Step 5; each block should have four pins, so make sure you solder to each of them. Check your work now that you’ve completed the terminal blocks to ensure that each solder junction is complete and appears shiny.

Adjusting the volume in a raspberry pi

Adjusting the volume in a raspberry pi

Many applications, such as PyGame and Sonic Pi, offer a volume control that can be accessed from within the application. The Alsa mixer command-line utility allows you to regulate the volume of other programs running in the background. Simply type Alsa mixer into the search bar and adjust the volume with the up/down arrows. Once you’ve got everything in position, hit the Escape key.

You can control the volume in Raspbian PIXEL by selecting Control from your toolbar. When the volume control has an X through it, restarting the Pi (you should reboot the Pi twice after installing PIXEL to recognize the volume control) may assist.

Frequently Asked Questions:

  • What is the proper way to attach a loudspeaker to a Raspberry Pi?

Answer; to connect the header to the PCB so that it can be plugged into your Raspberry Pi, some basic soldering is required. Afterward, you can either plug one of our confined speaker sets directly into the JST jack in the middle or solder the terminal slabs in and then link any speaker of your choice to them.

  • Is an audio amplifier required on the Raspberry Pi?

Answer; Between the Pi’s analog audio output and your speakers, you’ll need a stereo audio amplifier. This should work if you’re comfortable soldering and using the Pi’s 5V power supply.


In conclusion, Volume control is available in many apps, such as PyGame and Sonic Pi, and it may be accessed directly from within the game itself. It is possible to control the volume of other applications that are running in the background using the Alsa mixer control function. Simply enter the Alsa mixer into the search field and use the up and down arrows to adjust the level. Once you’ve gotten everything in its proper place, press the Escape key.

Controlling the level in Raspbian PIXEL may be done by selecting Control from the toolbar on the left. For volume controls with an X through them, resetting the Pi (you need to reboot the Pi twice upon installation for PIXEL to register the volume control) may be of assistance. In circumstances where you are unable to connect successfully, do not hesitate to contact a professional or just a knowledgeable person.
