5 Pcs 0.96 Inch OLED I2C IIC Display Module 12864 128x64 Pixel SSD1306 Mini Self-Luminous OLED Screen Board Compatible with Arduino Raspberry Pi(Blue and Yellow)

These are neat little displays for a good price. Was pretty easy to get going on a Raspberry Pi Pico (RP2040). Display is clear and big enough to see text even when the characters are ~2mm high. Build quality seems good enough for a bare PCB; has a 4-pin I2C header and 2mm mounting holes.By default, the device address is 0x3c, but if you are good with a soldering iron, you can move a tiny SMD resistor to change the address to 0x3D; the spot is clearly written on the back of the PCB near the header pins.There was no documentation with the displays, so you are kinda on your own. But, using Circuit Python, and ADAFruit's bootloader and libraries, and then Googling around, I was able to get it working easily enough. I did have to add a couple 4.7kΩ pull-up resistors on the SDA and SCL lines (the little circuit board attached to the display in my pic).Following another reviewer's advice, I powered it by 3.3v from the RPi output. If you need a starting point (like I did), I've attached a picture showing it working and a screenshot of the basic code I used to get it running. There's probably better ways, but this is just what I did. Hopefully, those pics are allowed. If not, you might have to Google around. Just remember to set the GPIO pins for your I2C, device address 0x3c, and the display dimensions (128x64) where needed.

I use an OpenSprinkler controller to run my yard irrigation system. The controller has an OLED display on the front that shows the status of the system, but over time it gets burned in, making it extremely difficult to read what’s on the screen. These OLED displays that I bought are a drop-in replacement for the one that came with the OpenSprinkler controller, so they are a very cost effective and simple way to restore the OpenSprinkler controller to like-new condition. I opted to go with the blue displays instead of the white ones that would have matched what came with the OpenSprinkler controller, but I’m sure the white ones would work just as well. I’m very happy with the quality of the display… it’s very sharp and easy to read.

These all work fine. If you are looking for Meshtastic displays, be aware that the Vcc and Gnd pins are reversed relative to the Rak wireless pinout so they are not plug in compatible with a pin header. If you are using a diy wire harness to connect them there they work fine. For the RAK nodes I am just using them temporarily to check function so I made a polarit swapping board about of a bit of project board.

Easy to use. MAKE SURE YOU LOOK KNOW YOUR SCL AND SDA PINS ON YOUR BOARD! Just wire, download a couple libraries to your developer application (e.g., Arduino IDE), download/open/edit example code and your off running! As for blue and yellow pixels, the top quarter of the display is yellow and the bottom three-quarters is blue. Don't expect the display to be able to use both colors over the entire display.

I tried unsuccessfully for hours to get this working with the ESP-IDF SSD1306 library but failed and eventually gave up, even after several rounds of ChatGPT facilitation. Had no issues getting the Arduino framework code running properly though with the Adafruit library.

To anyone attempting to run these on 5v, it DOES work, but there's a program variable you must set to change the voltage to avoid burning it out. It's simpler to just connect VCC to the 3.3v pin on the Ardruino board unless your project requires it.There are powerful graphics libraries written for this that are available for free from Adafruit. I recently got the Elegoo Uno R3 set and had been working through the demos, when I had the opportunity to add this to another Amazon purchase. All five worked right out of the box. I did have to change the address in the code because these are preconfigured to be 0x3C not 0x3D as the library assumes. I was curious what it would take to run one of these vertically, and it turns out you can rotate between four orientations with a single function call.I purchased the solid white displays, which do not have the black line across them that others have mentioned the two color displays have.

I've used these displays on several other projects, so I selected them again. The price is good, but not great. They work exactly as advertised. Note that some of the displays are monochrome (bluish green), but others have a few lines at the top that emit yellowish light. I like the ones that have a few yellow lines as you can highlight a title of whatever it is you're displaying.The only complaint I have is that Amazon does not include detailed dimensions of the part. I had to search other 0.96" parts (also from Amazon) to get the dimensions I needed. I integrate the display into a 3D printed housing. To get the front of the display flush with the housing, I needed to provide relief around the panel for a good fit. So I need all the physical dimensions.

The media could not be loaded. Screens are very small at 128X64 pixels, but they are bright. I really like the blue for my project. The Adafruit Arduino library worked great with some really excellent demo code. My esp-32 has no trouble running two of these at a time. The 5 units I received all came with I2C address 0X3C, but there is solder resistor in the back to switch to a second address if needed. This can be tricky to do and the 1 mm resistor is incredibly tiny and can be lost if you are not careful.Did I lose one of the address resistors, and break the screen from a small drop? Yes- but fortunately that was the same unit and I still have 4 left. If your expectation is very small, monochrome, and a little fiddly to work with you will have a good time with these little screens.
