Description: The SparkFun TeensyView brings you an easy way to add a small, white-on-black OLED to your Teensy development board. The 128x32 monochrome display is controlled with the popular SSD1306 IC, and is a great way to display debug information and to visualize data without the need for a serial terminal. The board matches the Teensy 3 form factor perfectly, and was designed from the ground up to be as flexible as possible while still being able to nest down into a low-profile addition for the Teensy.

The TeensyView comes with everything you need except the headers. Additionally, there are jumpers on one side of the board that allow you to configure how the OLED communicates with the attached Teensy. Since this is a headerless board, you have the option to solder on whatever type of header best fits your needs. Headers you may find useful with this product include the Teensy Header Kit, Straight Headers, Long Straight Headers and Female Headers.

  • To anyone attempting to use this product with a 328p:

    I’ve created a branch that supports 328 things. It’s up to you to divide the signal voltages down to 3.3V though.

    Direct link to branch zip:

    This includes an example specific to the 328, however, the template, screen demo, and high speed examples should work.

    example wiring

  • Under “Documents” lists “Arduino Library” so I ordered 2 thinking I could use these with any of the many Arduino boards I have kicking around. Just sat down to run the demo and find that the library won’t run on regular “Arduino” hardware? Not good. Now what?

    Just found that the “Micro OLED Breakout” P/N: LCD-13003 uses the same controller (SSD1306) and has Arduino library. Maybe that library can be used.

  • This is the bees knees!!

  • While of course a “mere” Arduino, say the Pro Mini, could not generated and plot a real-time frequency display for two audio channels, does this product actually NEED a Teensy, if the user is satisfied with “just” some text?? Library issues? What? It interfaces via a simple SPI… or is it I2C?… interface, after all?

    • Sure! The Teensy is just a SPI master with data/command control line added on. It’s all at 3.3V. The library uses the Teensy style SPI settings though, so it would have to be reworded (see hardware.cpp in the library).

      • The “re-wording” would be beyond me, and quite few others, I suspect. Sorry to mess with the catchy product name… (^_^) … but a library for us Arduino folk would be very welcome! Looks a neat device. Perhaps if you offered a free “development sample” to one or two with the skills?…

        Pehaps the text at the top of…

        … should be expanded to explain that while the library is fine for the Arduino IDE, the code will only work if the target board is a Teensy?

    • Schematic shows the spi lines are all that is needed, all you would need to do is hookup spi to an arduino and communicate with the OLED.

Was great, now doesn't work

The demo’s worked fine and I had it running with my own code for days. Just last week I decided it would be interesting to add to another working project and couldn’t get it to display anything. I’m not 100% certain that the TeensyView is the problem but don’t want to mess with it again to find out.


Have you contacted our technical support department @ ? They’re usually really good at helping figure out what’s going wrong with setups, I am sure they would be happy to help you troubleshoot the issue.

Best option so far, onboard Teensyduino OLED

I purchased the TeensyView to work with the Teensyduino 3.2 and AudioBoard. I used two connection kits to stack the the three boards together. From the bottom, Teensyduino, AudioBoard and then the TeensyView on top.

I was able to soldered, up and running in about 30 minutes. The TeensyView is working great so far.
