diymore 2.42 OLED Digital IIC I2C SPI Serial 128X64 Pixel LCD Screen Display Module SSD1309 for DIY Electronic (Green)

I bought mine directly from DIYMORE. It was tested in a system already functioning with a I2C 128x64 OLED display. The specified modifications were made to the board. There was no response on the display and an I2C scanner did not see the device. So basically non functioning and the company is not responding to requests for replacement.

If you are using this for I2C beware. You may need to force it into i2c (not SPI) mode. I never got mine to work for more than a few mins and thew it in the garbage. I got another one without SPI support that worked the first time.

Works just like it ought to. Decent build quality too.

These suffer from OLED burn in if used too long. Here is my display after about 6 months of displaying numbers. Note the small numbers burned in.

Does the board have a voltage regulator that will accept 5V? Or does it just kill the SSD1309 controller that runs at 3.3v? At least put a disclaimer on the ad that says attaching to 5V for 1 second destroys the controller.

This module was purchased as a gift for my brother. We are both studying for Engineering and love tinkering around with electronics. This module is on the pricy side and is rather small, but it a vibrant and easy to use display. The module supports both I2C and SPI depending on how you have the pins setup. There are also driver that you can find on the internet to help support the use of this screen or you can write the drivers yourself which is more fun by using the datasheet of the module to write data and read data to SPI/I2C memory-mapped registers. Seeing how much excitement he got out of it makes me want to buy another one for myself. Fast shipping too, awesome O-LED company

I used the Adafruit_SSD1306 library with a Moteino M0 board and it worked with no issues. It is setup to work with SPI by default, which is a little confusing because the board is labeled for I2C. Luckily several of the reviews pointed out that discrepancy so it was no big deal. I used hardware SPI and wired SDA->MOSI, SCL->SCK, GND->Ground, VCC->3v, and the remaining 3 pins to whatever digital output pins you want. I also modified the Adafruit example sketch to use hardware SPI (the sketch defaults to software SPI). So the initialization line I used is as follows: Adafruit_SSD1306 display(OLED_DC, OLED_RESET, OLED_CS); The display is nice and bright and daylight readable. I plan to buy many more of these in the future. Great display.

This was going to be a review about how to use this device with a teensy 4.0, but I guess now its a review about how this device tried to catch fire while I was eating a sandwich. And also how to use it with a teensy 4.0. I had this device working and displaying a demo, and suddenly and spontaneously made sparking sounds and released acrid smoke. If you intend to use this device, Id advise housing it in refractory and making it easily replaceable. First, connect SCL as labelled on the OLED to SCK on the teensy, SDA on the OLED to MOSI on the teensy, and the other 3 signal pins wherever. Next, open arduino library manager and install adafruit SSD1306, and instandiate a display object using the native SPI interface. I couldnt get the software one (the one that takes pin numbers for data and clock rather than &SPI) to work. Adafruit_SSD1306 display(128, 64, &SPI, OLED_DC, OLED_RESET, OLED_CS); After this, the display API worked, the bytes in the buffer returned by display.getBuffer are arranged in 8 pixel tall columns starting at the upper left. Also, why is the labeling for I2C while the default mode is SPI? Also, can I get a replacement that isnt melted?

Great oled display for Small gadget. One of the best oled you can find with 128x64 resolution. It works with luma.oled python library without hassle. Be aware of 3.3V vdd. This module does not have voltage regulator.

As advertised. Integrated it into my project today. Thanks.
