I am working on a design using the Teensy 3.2 board and needed a reliable method of connecting to all the pins on the board - not just the exposed on the side! I my searches I ran across the Breakout Board for the Teensy 3.2 board. This board fit my needs perfectly - it has allowed me to put the Teensy board on a breadboard with ALL the connections available for use! The board is very well made with attention to detail! I will definitely keep this board in mind for all of my projects needing a Teensy 3.2 as I can not think of an easier way to gain access the the terminals on the bottom of the Teensy 3.2 board without resorting to fly-wiring (which I despise with a passion!). Check out the images that are posted on the website. If you don't feel you are good at soldering then go with the pre-built unit but for those of us who have over half a century solder this board is a breeze!

I would love to see a version of this with all the pins broken out into screw terminals. As it is, I'm going to end up cutting some of those proto boards from adafruit to give myself enough room to mount some. I know they make boards that are just rows of tied together pin holes (the name is escaping me), but they all seem to come in tiny or huge..

Awesome stuff though. Would have liked to seen on the pinout sheet what the pins in the center of the board did (I figured it out, but it wasn't as obvious as I'd hoped)

Thanks!

I have designed and built several different boards for the Teensy processors, including a few different ones for the Teensy 3.6/5

But I wanted a quick and dirty one to use to do some more breadboard testing, so I thought I would give one of these a try.

The instructions for assembly were clear and it works well. While I will continue to do my own boards, I will next assemble the 2nd one I purchased with a T3.5, so that I have a breadboard version to try out code changes on that chip as well.

Again nice board.

It seems not all pins are wired, so the microSD extension failed to boot our RPi2/3/Zero boards.
It should be written on the extender description.

I needed to make one of these expansion boards, but I found yours, and I'm very happy with it.

I bought a few different packages, but I am currently using the presoldered dip64 populated with a T36, and I couldn't be happier with it.

Thanks again for making my life easier, any time I need a new teensy I am going to order it through you with an expansion board.

I hope you order the teensys from PJRC!!! I want Paul to get as much money as possible for these excellent microcontrollers​.

I've used this on several breadboard projects, both 5v and 3v, and it works great. Super handy when you need to try your prototype somewhere away from your bench power supply.

I was really surprised at how well documented and packaged this kit was.

I expected a manila envelope with some printed paper, but I got a nice card and pinout diagram. Super impressed!

The pictures on the website show the unit with the carrier rails removed and with headers
installed, and show the kit as including 4 40-pin headers. I ordered the unit assembled and
left the selection as "leave carrier rails on." When I received the unit it the packing slip listed
the 4 headers but the unit did not have headers on it nor were there loose headers in the
package. I thought that an error had been made and the headers had not been put on, but
when I went back to the web page and looked at the other choice, I saw that it was "remove carrier rails
and install headers" which implies that the default which I had left unchanged when I ordered
meant rails but no headers. It would be clearer if the default option was "leave carrier rails on
and do not install or include headers" and if the packing slip with the package did not list headers
which are in the photos on the web page but are not in the package.

Having one Teensy 3.6 mounted with all pins readily accessible without having to spend all your time soldering temporary breakouts is really great. This board makes it so much easier to quickly test running all six UARTs or all four I2Cs if you're feeling up to it. The savings in time pays back in your first use and the board will continue to same more through all following prototyping projects.

The documentation is detailed and easy to follow - rare for this business. I am a total amateur but the quality of the PCB looks high. The board works perfectly and I have breadboarded with it using every single I/O pin.
I must say that I now prefer the breakout board, rev. C because: 1. the usb-Vin switch is on top and 2. the rev.B board is very wide and covers all the holes on my breadboard making insertion of breadboard wires difficult.
Excellent product.

I finished assembling my Teensy 3.2 Breakout (Revision B, Standard) kit and it went smoothly. The directions are well written, complete, and easy to follow. The PCB is top quality as are the other parts. I just wish I hadn't already soldered headers on my Teensy 3.6 or I would have one coming for it too.

This guy is really on point with his breakout boards. They work perfectly every time. oasf;oindasoin;oind;oidnsa;odinsad;oin

TLDR version: If you have found this product via a search for "Teensy breakout" or "how to mount Teensy 3.x" then you have found the exact product you are looking for, look no further.

Not to overuse the classic "I never write reviews but..." line, but I really don't. Okay, I almost never write product reviews unless I feel compelled to convince others not to buy some sort of ersatz garbage, but today that is not the case.

I spend my days working as an engineer, and my evenings as a mad scientist (okay, just a different sort of engineer) working on a prototype robotics development platform, and I love the Teensy boards, they are truly what Arduino should be, and after using my first board I cannot see myself going back. That said, I am a perfectionist, and although I am working on a prototype, I also view it as a sort of physical manifestation of my resume, and as a result I care a lot about form/fit/function simultaneously, and as-is the Teensy boards do not share in my mentality as they do not have any sort of proper means to mount them. I could go on for pages about how that was a massive glaring design oversight, but I won't, the boards are what they are (which is just good enough to make it into my prototype in a few spots supporting the main controller) and that is where this breakout board comes in.

I have purchased two of these boards so far, and in two separate orders, if nothing else that should say something about the product.

These boards are an example of good engineering and great product development, I know, I know, those are strong words for such a simple product but really it's the simplicity that makes these boards great. They are made of [apparently] high quality materials, all the pins line up, and it does exactly what it was supposed to do, with no frills, added features, or anything else to get in the way of things.

The closest competing product that I could find (which is priced almost the same) is a breakout shield which gives the Teensy the same form factor as a standard Arduino Uno. Sure, the competing product performs an almost identical function, but it was clearly designed with added features in mind, and to make it so that less-motivated folks can stick to their pre-packaged Arduino add-ons instead of [gasp] breaking out the soldering iron one more time. Disclaimer: I actually own one of these boards, but I have yet to assemble it, I prefer the smaller package of this breakout.

This product was also my first Tindie purchase, and was the reason I found Tindie in the first place (Tindie is pretty sweet).

I would have given all 5 stars, but I didn't want my review to seem manufactured so I gave only 4 stars for shipping because (don't hate me) Amazon is faster. That said, Daniel shipped me my second order while out of town thousands of miles away, and that is dedication.

Teensy has been my "go to" microcontroller for small/medium projects for several years starting at the 3.0 version. At times I wish I was able to use the extra pins for a couple more inputs or outputs but it was inconvenient to get to those underside pins. This breakout board solved that problem very well. And the result is still proto boardable with a spare row of pins on each side. The board was well engineered and nicely documented. It took me about an hour to assemble one. So far my testing has been successful. Good job. Thanks!

Recent work with Linear Technologies' ADC and DAC hardware got me wondering about using the other SPI config on the Teensy 3.2 and for some reason, I found the 3.2 Breakout board online. It immediately struck me as a useful addition perhaps for future projects, so I decided to buy a few and check out the setup and potential usefulness of access to all pins.

Shipping was relatively quick (Australia) and the packaging and documentation excellent.
I was immediately struck by how thoughtful everything seemed to be packaged and presented.
The board is very good quality, well marked and the components even though small fitted with no problems.

Although it initially takes some time to construct, due to a lack of familiarity, it is a straightforward process that I still would not rush.
I could even see some scope for variation of header components but building it for breadboard use is a logical starting point.
The construction documentation was good and easy to follow. Some aspects of it I wondered about but that could be just me.

The Breakout board will though come into its own when used in special projects where getting the most out of the Teensy 3.2 is important, if not critical.

It is relatively pricey compared to the Teensy 3.2 itself but clearly, production volume would be a factor in this.
Overall, an important contribution to the Teensy world and I'm glad I found out about it.

I've used a few of these, in various versions, and they are great. The only 'simple' breakout I've found that gets all the pins plus a few other features without making me buyoff on an Arduino Uno layout or large footprint that includes breadboard areas and interfaces that I don't always want. Not to mention breadboard compatibility.

It's not often that I feel compelled to announce my admiration for a product, but I must tell you that Daniel Gilbert's Teensy 3.2 breakout board is just outstanding.

It's a board that the Teensy 3.2 permanently mounts to, increasing the footprint of the Teensy to 2.4" x 0.9". Considering that the Teensy is, well, teensy, the small size increase is not a big deal.

What IS a big deal is that the pads on the bottom of the Teensy are now brought out to the edge of the breakout board. Now all the pins of the Teensy are readily accessible. I [U]wanted[/U] those pins! Now I can have them.

www.tall-dog.com. $12. Worth every cent!

This breakout no only lets you use all the Teensy's pins, it also comes with great documentation. Works with both 3.2 and 3.1 Teensys. My only suggestion is that it would be nice if the selection DIP switch was on the top of the board.

This is a great board for easily prototyping/breadboarding your teensy -- some of the pins are not easy to get to, especially on a breadboard. this is well thought and easy to implement. Excellent communication & post sales communication.

The Teensy breakout board makes it much easier to prototype with the Teensy. I have just experimented enough to verify everything works, but I plan to hook it up to a Mercury FPGA board (for high-speed quadrature decode and other sensor aggregation) and a motor controller, and being able to prototype things on a breadboard will make getting it working much easier.

I've purchased both the assembled board with a Teensy 3.2 already on it and I've purchased the kits. The documentation and the quality of these breakout boards is super!

Great breakout for the Teensy. Customer service provided by the seller is excellent. Stands by product and is quick to answer any questions. Would like to see this board combined with the audio shield. But for now, this does the trick. You really don't realize how many pins the Teensy has until you get one of these.

The Teensey is truly that.. so it is not going to work on a standard breadboard setup by itself. This adapter board (and associated parts) allows for having a Teensey you can get to all the pins on, AND works perfectly on breadboards.

The directions are very clear and include detailed drawings step by step. Everyone should provide directions this good! The Board Layout is clearly well thought out and although it takes a bit to put together with lots of soldering it is not difficult. The silkscreen is clearly marked and the board also comes with a Pinout Diagram showing the Teensy and it's relationship to the pins (in the same style as the Pinout Diagram from Teensy itself).

I ordered mine with the full parts kit which includes the headers and the Pogo Pin etc. Added on the Clock Crystal, Switch, and USB Host Capacitor as well. All of the optional parts were excellent.

I'm a Very Happy Camper

This thing kicks ass, it makes the Teensy 3.2 much more usable. Next time i get one of these i'm going to get the assembled version for ease.

Very useful pcb for the teensy, which can be even configured before purchasing
shipping to Europe (Austria) was very smooth.

I think the Teensy 3.1 is a great Arduino for a great price. It's fast, has lots of memory, better analog capabilities, and good documentation.

My only complaint is the actual form factor of the pinouts themselves. I want all the pins broken out along the two long edges, not folded inside the PCB or accessible via a soldering pad on the bottom. I shouldn't need to purchase a separate "breakout" board just to get easy access to all the pins. Perhaps Teensy 3.2?

This is a great little breakout board - my only gripe is that the documentation asks that I only tack a few of the right-angle pins. The first time I tried that, half of the bottom pins failed to connect. Second time I soldered every single pin, and that worked great.

Other than that, the quality is excellent and the documentation is great - includes a handy card with all the pinouts.

Just assembled my first of two breakouts. I have a project requiring the second i2c bus and this was perfect (I ruined one teensy trying to hack some pins onto the bottom already). The instructions along with super clear drawings made assembly a cinch. I added the DIP switch for flexibility in powering the device as well. Very well done!
PS I would pay a couple more bucks for a handy reference card for the pins like paul makes.

Just received this today and the shipping was super-fast. Communication and documentation are great too. I'll be putting the kit together in the next few days. Thanks!

Very highly recommended. Shipping was fast, and the product is awesome. With this breakout board, my Teensy3.1 became an even more powerful animal. Thank you!

This makes the teensy so much easier to use.

When assembling I would recommend cutting the leads as late as possible so they can help with any alignment issues.
One change I would love to see is a jumper between Vusb and Vin so the trace can be cut before soldering but still easily connected again if needed.

Excellent Product, Quality Assembly (for Non-Kit Version)

This is the best ever B.O.B for What is the best EVER Arduino compatible board..

A very good quality board that provides easy access to all of the teensy's pins.
It comes with all the needed header pins and mounting screws.

Provides all the necessary pins to attach the Teensy 3.0 or 3.1 to breakout board. This includes the pins for the 14 pads on the bottom of the board. Just don't forget to add the 32.768 KHz Crystal - cut the pads for power and add the 150 uf capacitor, prior to attaching the Teensy to the breakout. This breakout board brings the second I2C port out to the breadboard pins (as well as the other functions).
I would recommend one change to the assembly instructions: take on of the 5-pin lengths of through-hole headers from step three and solder then into the end of the teensy prior to step one. And after tacking the 14 pin header (prior to soldering all the pins) insert into the breakout board to check alignment.
