UCTRONICS 2 Pack 0.96" OLED Display Module for Arduino, 12864 128x64 Pixel SSD1306 I2C Serial Mini Screen, Yellow and Blue

If you use the recommended libraries you will tie up so much memory an Arduino Uno has no memory left over for a program. If all you need are characters (no graphics) then look on GitHub for "ArducamSSD1306" and you'll find a lightweight character only library.There is no drawing of the mounting dimensions, at least none I could find. Kinda makes using the display difficult if you can't mount it. As we speak I'm printing a test mount. I'll add to this when I get things to work and provide dimensions.Ok, this is what I printed and it fit.Mounting holes are 1.95 mm dia.Horizontal spacing is 23.31 mm, center to center.Vertical spacing is 23.62 mm, center to center.

Your browser does not support HTML5 video.  These couldn't be much easier to wire up to an Arduino. Download the library, connect four pins, and you're off and running.Be aware that the top two rows (16 pixels) will always display in yellow, and the rest of the panel displays in blue. It's a nice yellow, and opens up some artistic possibilities if you're a glass half full kind of hominid.

Works great for Arduinio Uno. Working with DHT11 for a temp/humidity monitor.However I suggest using a different library as the ArducamSSD1306 ones can use a lot of global memory.Since I'm only displaying temp and humidity I used a text only ssd1306 library that greatly reduces the sketch and global memory size.(13264, 41% and 1565, 76% down to 7444, 23% and 275, 13% The sketch, global sizes before and after changing libraries, respectively )Go to GitHub and search on 'SSD1306Ascii' Please note the caps. You'll find it. Download it and use it.Works great!

Display was packaged well in the typical sealed anti-static bag. All necessary pin headers arrived with the display ready to be soldered on by the user. Documentation was surprisingly good and informative. One thing to note is that the Arduino library recommended to be used from the manufacturer was not available in the Arduino Library Manager. I ended up using the SSD1306 and GFX libraries from Adafruit and had no issues. At this price point and with the good quality of the screen, I will definitely order again for future projects.

Was able to get this running after a little research. Use the right libraries:#include <ArducamSSD1306.h>#include <Adafruit_GFX.h>#include <Wire.h>Made a nice little "Weater Station"!I ended up setting up a Nano for my "sensor station" that connected to my NodeMCU (master) in an I2C bus along with the display on I2C address 0x3c (default) as well.Appears to support al required protocols and looks good!

Amazing, and very easy to get going, they work great, just read the little instruction sheet, download the library files from the link they give in the instructions and you are all set. I think some users are will find this helpful, as I've read some users were unable to compile the example. Just change the chevron symbols to quotes on the two includes as shown below. The chevron symbols <> tell the compiler to locate the files from the default library location, and the quotes tell it to look for it in the running folder of the program script. I run my projects from my data drive, so I changed it to quotes. These are really nice displays, they are crisp and sharp, I started to draw bitmaps and do some animation on mine too, having lots of fun with these.#include "ArducamSSD1306.h"#include "Adafruit_GFX.h"

This screen functions very well and is incredibly inexpensive. There are plenty of libraries available. It is a super easy way to add a cheap GUI or readout to your next project. And at the price really why not> Just be ready for less-than-perfect work and materials.I only needed a very simple numeric of alphanumeric readout and was considering an old-school 7-segment or 14-segment display, or an LCD character display. As this small OLED display was actually cheaper than those other options I chose to give a shot; I am super happy that I did. it's so much more flexible than either the 14-segment or LCD characters would have been and the text is really sharp, bright, and very readable.The only downside that I ran across (as was to be expected for a $6 OLED screen) was second rate materials/build quality. I had to desolder once (wanted to flip the orientation of the connector I was using) and lost a pad in the process... it can be overcome, but was a pain. So solder in your pins/connector(s) and then leave 'em alone, this board does not appreciate being reworked.All that said I will likely buy one again if I'm in need of a simple, inexpensive display.

I am all for paying Adafruit a premium price on the products that they add their tremendous value to. Other products are offered as a reference of the compatible product. Some quick research and I realized I could cut about a dollar or two off the. bill of materials (BOM) for a few of my projects. I do a little research to decide what products I will take a chance buy in quantity at ,major discount over some name brand product, I look for support tickets or scan the C/C++ and/or MicroPython/CircuitPython mention of the board by it's manufacturer versus referred to the protocol or higher level interface you use to program the hardware. This is a nice little display. Probably going to make a small quantity bulk order in the coming days/weeks.
