Product Overview

The ShillehTek 3.5mm Stereo Audio Jack Breakout Board makes it easy to connect a standard AUX/TRS 3.5mm cable to your Arduino, Raspberry Pi, or audio projects without messy soldering directly to a tiny jack. It breaks out the Left, Right, and Ground connections (and in some versions extra pins for jack switching) so you can route audio into an amplifier, feed audio into an ADC, or build simple audio input/output experiments. It is perfect for DIY audio builds, sound-reactive projects, line-in monitoring, and quick prototyping where you want a clean, reliable audio connector.

Frequently asked questions

Yes, it can connect to Raspberry Pi audio projects that need access to a standard 3.5mm stereo TRS jack. It breaks out analog Left, Right, and Ground, so your circuit must handle the audio signal appropriately.
Yes. The ShillehTek version is pre-soldered, so you can connect wires or header leads to the breakout pads instead of soldering directly to the small audio jack, making breadboard and prototype wiring easier.
It exposes the standard stereo TRS connections: Left audio, Right audio, and Ground. Some versions may also include extra jack-switching pins, but the main use is routing analog audio signals to another circuit.
Yes, it is useful for bringing line-level stereo audio into an Arduino-compatible circuit, such as a sound-reactive LED project. Add the required input conditioning or ADC circuitry for your specific board and signal level.
This board is for standard stereo 3.5mm TRS connections, not TRRS headset wiring with a microphone contact. If your plug has four conductors or needs mic support, verify the pinout before buying or wiring it.

Great TRRS module for projects

This tip-ring-ring-sleeve female connector on a circuit board has good solder joints to the pins and a good firm fit and contacts. It comes in a silver static bag with a square pad of foam to protect the pre-soldered pins. Overall quality looks good and you should be able to use this board for you sound related projects without worry.

Helpful little tool

A surprisingly helpful little circuit for splitting out the signals from a TRRS plug, I was able to use this to separate the signal flows into and out of my handheld ham radio. The jack accepts a full 1/8" TRRS plug and splits out the signals in clearly labeled and identifiable pins, easy to add to a breadboard for experimentation. There's nothing more to this than raw signals, but if you have the interest in experimenting with the output of a portable radio, this is the perfect start.

Interface Only

This module is only a TRRS (tip, ring, ring, sleeve) interface and has no DAC so be sure that's what you're looking for. It's basically a headphone jack interface. It works just fine.

3.5mm jack to breadboard adapter

This is such a simple converter, but if you work on any kind of audio project using breadboards, this little thing is wonderful. I must admit, it seems so expensive for just one of them, and so simple that you could just make one yourself, and you easily could (I have in the past) . . . but by the time you do, you could have just gotten this one and saved the time and effort. I tested it, and it works. It’s a TRRS adapter, so you have all the connectors you could need. While this is a 5 star product, I’m going to subtract one star for “value” since this should really be a 5 pack for this price. But, the convenience I guess is worth it. 4 stars overall.

Ok headphones adapter for Raspberry pi projects

Pros:* Header came pre-soldered* Easy to use* Labelled on silkscreenCons:* Plastic on surround seems flimsy* May not be good after too many insertions

Great addition to my breadboard design work involving 3.5mm connectors.

One of my customers uses a product that includes a pressure sensor assembly with a 3.5mm 4-conductor plug on the end of the cable. When I was developing a simulator test box before I had this 3.5mm audio jack breakout board I was having to solder and unsolder wires to the prototype jack while experimenting.This breakout board allows me to plug this board into one of my breadboards, as seen in my photos, and no more soldering during my experimenting for my designs. In the schematic shown I only show the part of the simulator that has two precision 1K resistors in series and how the meter shows the expected 2K resistance between TIP and SLEEVE.One thing I’d like to see is another row of pins parallel to the existing row of pins to give it more stability when plugging in or unplugging a 3.5mm plug. Not a big deal for something that isn’t part of a final product where users would be plugging and unplugging often.Nice addition to my experimentation and design work with a breadboard.

Does your build even have a phone jack? Mine does.

Who knew that a nothing little part like this could instantly make my lil Rpi more functional than any Apple product on the market?This mod simply works. With a physical connector, even.It's not the most durable item in the universe, but if you're building an Rpi you're likely not doing so with steel gauntlets on your hands. All you need to do is make sure you have room and an exit port, and it should work for most builds. Pretty easy stuff.

Works fine but a little expensive for what it is

This audio jack adapter from Shillehtek is handy for prototyping. The pins were pre-soldered, and the module fits a standard breadboard. The price is a bit high for what you get, but it does work.

Gotta have an aux port!

Works great, tested it and am going to add it to my own device.

Perfect Little Module for Audio DIY Projects

This breakout board is one of those small components that makes wiring up audio projects way easier. I used it in a Raspberry Pi setup to handle both audio output and microphone input, and it worked exactly as expected. The pre-soldered header is a nice touch — saved me a step and let me drop it right into a breadboard or jumper wire setup without messing with the iron.The pin layout is clean and well-labeled, so integrating it into a project is super straightforward. I’ve used it with both Arduino and Pi boards, and it worked well in both cases. Whether you’re routing basic audio signals or tinkering with TRRS headset functions, this gives you a reliable, compact interface without having to strip or rework a cable yourself.If you're into prototyping or building your own sound modules, this is a super handy piece to have around. It saves time, reduces errors, and just does its job without getting in the way. Definitely worth picking up if you're working with audio on any kind of microcontroller project.

Versatile breadboard audio jack

Man is this useful! It's a breadboardable audio jack. I've used this over and over when I'm prototyping new audio projects in a breadboard. It's so easy to drop in and wire up as needed. The audio quality is just fine, it's not too flimsy either. This is one of those simple parts I wonder how I ever lived without.

Just what I needed.

While building an Arduino digital radio, I came to the issue of how to connect my headphones to the project. I thought about adding the complexity of a Bluetooth connection, but using the KISS method, I landed on this easy-to-use hardware solution.This audio jack was so simple to add to the project.This jack breaks out all of the pins for a stereo headphone jack and will allow for quickly connecting headphones to the project.The output of my digital radio was already audio-ready for headphones; this jack was the perfect and easy solution.I recommend this stereo jack board for your projects.

Quite versatile

I'm an embedded software developer and often have a need to put together different sorts of interfaces to connect to different devices. This little board is quite useful for the sort of stuff I do. While it can be used to drive a standard set of audio signals, I'm also impressed that it can be used for a variety of other sorts of interfaces just be connecting it to the appropriate (often GPIO) pins of the processor being used. For example, I have an application that does not need stereo but that needs an I/O for "push-to-talk" automation. I can move on wire and have the less common interface that I need. I especially would recommend this as a great device to have in your parts stock especially if you work with things such as radio that might need a controller that connects to an external device via a 3.5 mm (1/8 ") connector. Especially good for Ham radio folks but that is just one of many uses.

Useful and convenient

I love components that come with pre-soldered pins! You definitely need to hold it in place when you are plugging/unplugging headphones, but that's a small inconvenience that I can certainly live with in relation to the price and "ready-to-go" nature of this board.

Worked great

I've been using one of these with a bunch of dupont wires soldered to it in some freaky spider headphone plug. This is such a simple and elegant solution that works very well. You do have to apply some downward pressure on it when plugging something in but that is to be expected.Super happy with it.

As described for a simple item.

You see what you get. Simple and works fine.

Great for Prototyping

This sure beats sticking alligator clips to a headphone plug! You can use it to connect headphones with microphone to a DAC, or use it for connecting your Raspberry Pi to something like a Baofeng radio using the appropriate patch cables. Of course you'll need the appropriate wires to do so, which can easily be purchased here on Amazon.As my title says, this is for prototyping. I recommend getting the socket by itself (no breakout connector) for any final PCB builds.

Decent board came well packed

The media could not be loaded.









This tip ring ring sleeve break out board. It’s nice and handy. This saves me from wiring for some of these things. TRRS wirings are uniquely different than your typical stereo 3.5 mm cable so make sure you know that you need a TRRS if you’re getting this.

Audio output board for arduino & raspberry PI projects.

Added this to an arduino for some sensor fun. Now when my little bot project recognizes someone it makes funny noises! :)

Pre soldered for us lazy people

Got this for prototyping, so pre-soldered pins save me time. Beyond that, this is a pretty standard breakout board for a 3 or 4 ring audio jack. This one is a little pricy—you can get an 8-pack of basically identical parts for almost the same price on Amazon, but not pre-soldered. Quality seems good with good quality PCB and soldering. The jack makes a good connection to my headset, and fit nicely onto a breadboard for prototyping.

Good Idea - My Sample not Reliable/Functional

This review is for ShillehTek Pre-soldered 3.5mm Stereo Audio Jack Breakout Board – TRRS Headphone/Video Jack Module for Arduino, Raspberry Pi, Audio Projects, DIY Electronics, Sound Modules (1pc) - Soldered ModuleShillehTek Pre-soldered 3.5mm Stereo Audio Jack Breakout Board – TRRS Headphone/Video Jack Module for Arduino, Raspberry Pi, Audio Projects, DIY Electronics, Sound Modules (1pc) - Soldered ModuleThis is a 4 position 3.5mm female adapter to 0.1" pin header adapter.Unfortunately, I found this to provide unreliable connections to a Bose TRRS headset/mic device. The DC resistances are not consistent between the pins and the barrel connector. I also tried using a signal generator to drive the right/left earpieces and could not get consistent audio.The idea and convenience of this adapter is good, but my sample has problems. I suspect contamination inside the barrel connector that makes contact intermittent.

Perfect for Audio Projects!

worked flawlessly for my Raspberry Pi audio project. The labeling (TIP, RING1, RING2, SLEEVE) made wiring super simple, and the pre-soldered pins saved me time. Solid build quality and great value for the price. Highly recommend for prototyping or DIY audio setups.
