> 24 hourThese 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.

> 24 hourIf you have a lot of pixels on on a line lit, it is noticeably dimmer than when there are just a few pixels. For instance, the descenders of y and g are significantly brighter than the body of line of text. Not a deal breaker for me, since I havent found this size of OLED display anywhere else.

> 24 hourThis 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

> 24 hourThis 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?

> 24 hourGreat 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.

> 24 hourWorking on some projects with a Raspberry Pi Pico using a ported SSD1306 library. My project required I2C communication and I had some difficulty at first. I validated the OLED worked via SPI, so after a bit of fiddling I figured out the combination: 1. Move R4 resistor to R3 2. Bridge the R5 pads (0 ohm resistor, solder bridge or wire will work) 3. Connect the RES pin to source voltage (connected to RUN pin on Pi Pico) 4. Connect the GND, VCC, SDA, SCL lines normally Step 3 wasnt documented anywhere I could find. Figured it out after some Googling and trial and error. After all was said and done, I was able to run this OLED at 3.3v and 5v via SPI and I2C. I tested I2C up to 800 kHz (didnt try higher) and it worked great. I dont know if running it out of spec will kill it faster, but I was impressed with the variety of options that worked. The display refreshes just a tad slower than the smaller OLED displays I have, but thats not a knock against it. I have the green and blue versions and both look amazing and perform great for my use case. As someone else said, the pins are labeled in a weird way, but its easy enough to figure out what goes where. Would definitely get more if needed.

> 24 hourWorks just like it ought to. Decent build quality too.

> 24 hourHad a little trouble getting it to work. Support was quick and efficient. Screen works. It’s bright and crystal clear. Just bought a second to duplicate my project with a different colored screen.
