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

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.

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.

Had 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.

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.

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.

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.

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.

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
