SparkFun Transparent Graphical OLED Breakout (Qwiic)

The future is here! The SparkFun Qwiic Transparent Graphical OLED Breakout allows you to display custom images on a transparent screen using either SPI or I2C connections. Brilliantly lit in the dark and still visible by daylight, this OLED sports a display area of 128x64 pixels, 128x56 of which are completely transparent. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system making it easy to get started with your own images. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The Arduino sketch required to drive this display requires quite a bit of dynamic memory, meaning that it is not going to fit on a smaller controller like an ATmega328. Control of the OLED is based on our new HyperDisplay library and any controller with larger RAM should have no problem. In addition, your 3.3V source should be robust enough to supply around 400mA to the display.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

  • 128x56 transparent pixels (128x64 total pixels)
  • Display area 35.5 x 18mm
  • Glass area 42mm x 27.16mm
  • 1-bit color depth
  • I2C or SPI operation
  • 400 kHz I2C, 10 MHz SPI
  • I2C Addresses: 0x30 (Default), 0x31
  • Qwiic compatible and standard PCB footprint
  • Operates and communicates at 3.3V
  • Less than 200 mA current draw pixels all-on

Everything You Should Know About HyperDisplay

February 20, 2019

This is a tutorial to go in-depth about the SparkFun HyperDisplay Arduino Library.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

We welcome your comments and suggestions below. However, if you are looking for solutions to technical questions please see our Technical Assistance page.

  • Would this work on Arduino Nano? If so, what are the schematics? Would the code still be the same?

    • Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above or the steps in the troubleshooting section, to get started with posting a topic in our forums.Our technical support team will do their best to assist you.

      That being said, the schematic for this board can be found under the Documents tab (underneath the product pricing, it can be easy to miss with the white-on-white tabs). Additionally, the hookup guide for this display is also linked under that tab. It will have all the hardware assembly and code examples to get you started with using the display with our ESP32 Thing Plus. Unfortunately, as mentioned in the hookup guide, the code to get this display running does require a lot of RAM. Therefore, I don't think the Arduino Nano will work with the display.

    Can you post the datasheet for the TOLED itself? Would be very helpful. Thank you. ACTUALLY SCRATCH THAT-- looks like it was in the Github. Thanks!

    • Oops! We're posting it on the Documents tab anyway b/c that's where it oughtta go! Thanks for calling that to our attention. P.s. even though it says confidential we have gotten permission to share it with you all.

  • Is it possible to replace the flat cable? I have a project I've been working on for a while, trying to find a transparent OLED display, but I need the flat cable to go from the display at a 90 degree angle, and be a little longer.

    • Good question - glad you asked! It would be very challenging to remove the cable from the glass of the display, but it is really easy to replace the display module thanks to the FPC connector on the PCB. I'm wondering if you might still be able to use this display though, because the cable is very flexible. There is a short (~1mm) stiffener protruding from the glass but after that the cable can bend more than 90 degress with a pretty small (less than 1mm) radius. I will say if you choose an extreme bend in the cable that it is best not to bend it back and forth too many times. I hope that can help!

Display is Good - Sparkfun Drivers not flexible

Hello, I bought this display under the impression that although it is graphical, the Display driver would support writing (drawing) text. However, that is not the case.

customer support said "The display is matrix rather than a character display"

I know, but matrix displays can draw text with a capable driver...)

I found this driver: https://github.com/olikraus/u8g2 That is capable of writing beautiful text on the display!

Open the "Helloworld" example:

Uncomment the following: U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE);

Support 8 lines on the display.

Then write to Position (x) and Line (Y) using the command: u8x8.drawString(0,0,"hELLOW WORLD);

Just what I wanted!

Good! display

I use it. https://www.denshi.club/cookbook/arduino/mkrzero/mkr-zero-8-oled.html

That's really cool, thanks for sharing your project!
