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)

Good price for the product. functions great and simple to install

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 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.

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.

This product works great and functions as I expected. Also, this is not a TouchScreen Device. There are however a couple of gotcha's that I am aware of... 1) I have read places these devices are not 5V tolerant despite being sold as being so. Apparently some users have had theirs burn out after running for some time at 5V, so if you can use 3.3V just best to be safe and run with that. 2) ESP32 Driver Problems!!! Ok, so this isn't an issue with the device but something you should be aware of if you are planning on using it with an ESP32 device over I2C. Apparently Espressif updated the core drivers for I2C to "fix" them in versions beyond 2.0.14. As a result many people have discovered their favorite Library for working with the SSD1306 is now throwing internal errors. I tried a couple different libraries with the same results. I found the only fix (unless you wanna rewrite a SSD1306 Library) is to lower the version of the esp32 SDK by Espressif to version 2.0.14. Once I did that everything started working just fine.

These are great for integrating output on an Arduino. The documentation and sample code for similar modules makes it easy to implement. It is a simple matter to connect to a network time server and update date and time for example. They are very small, but the design is good and it seems relatively durable. I haven't yet taken the protective film off, but with it on the screen is very clear, responsive, and readable.

These work just fine if you need a tiny screen for a project. Works with the Adafruit SSD1306 library. They are bright and readable. The second color is the top 16 pixels, 1/4th of the screen.

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.

5個ともすべて正常に動作しました。 SSD1306の標準仕様に準拠しているようで問題なく動作しました。

Worked great.

Vienen bien protegidas en una caja de plástico cada una. Funcionan como se espera y a precio razonable.

Love It i use it as my 3D printer Mini Screen

Muy bien
