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

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

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.

If 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.

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

Working 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.

Love the extra screen real estate. Im building a cyberdeck/smart watch project with this screen and it is a fantastic fit for the purchase. Highly recommend Green.

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

I followed the instructions for converting to I2C but could not get it to display anything on my Raspberry Pi Pico until I hooked the RES to a GPIO pin set for OUT and PULL_UP and pulsed it low in my program. Works OK now.

Using with SPI, works great once I figured out how my mcu board talks to SPI. I love that it is green. Wonderful

Libraries tried so far: Adafruit SSD1306; SSD1306Ascii; U8g2. All of them have an option for software SPI which is what I used with the Raspberry Pico board. Im pretty sure if it will work with this board it would work with any. I havent tried I2C mode yet, but I dont really feel the need too considering how easy the SPI was to utilize, especially since you could even bit bang the SPI. Its basically an upscaled 1306 and therefore has the same resolution so, in theory, the same libraries should work. I got the yellow version on sale and am not disappointed. I have had multiple problems trying to get my dual rp2040 project up and running, but luckily this has not been one.
