Huhushop(TM) white 0.96" I2C IIC SPI Serial 128X64 OLED LCD LED Display Module For Arduino

I'm surprised at how small the unit is. Had to use a magnifying glass to see the pinout markings. Had to change the address as per previous reviews and it worked with the Adafruit sample program. The display is very readable so would be nice to use in a very small project. Now to find out how to display what I want it to actually display is another issue. I can't seem to find a simple sample program to say just display a line of text (changing font size, etc. included).

One worked, one didn't.The one that worked (I use I2C) worked perfectly, the other was DOA. YaFang was prompt to refund. I like this unit because it offers the possibility of either SPI or I2C, although I can't think of a time when I would preference SPI.Packaging was not ESD safe, which is what I am assuming killed the one.

This unit is kind of difficult to get going if you're new to Arduino so I'll try to give you a starting point.First off the sketches needed to run this item can be found on the Adafruit site here:[...]Load those libraries and then open the Arduino IDE. Select File>Examples>Adafruit_SSD1306>ssd1306_128x64_i2cThe default address of the unit as shipped is marked on the back of the board silkscreen as 0x78 however this is wrong. My unit actually has an address of 0x3C. To fix the Adafruit code:Scroll to line 61. Find in the parenthesis 0x3D. Change this to 0x3C, save the file and upload it to your Arduino. Once it is complete, you should start seeing the Adafruit demo program running.If your display stays black and appears to do nothing, you've most likely gotten the address wrong. To find out what yours is, you need to run an I2C scanner. There are several out there but on my Mega most of them didn't work. This one does however:[...]Once you get that demo running, you can start modifying the code to display what you want. Happy hacking!

Original review:I rated this at three stars because the part I received was not the part pictured. It was a 0.96" OLED display but it has a 6 pin SPI port, not a 4 pin I2C port. I have found no way to make it work via I2C. But I decided to keep the part as a stripped down SSD1306 text-only library consumes only about 3000 bytes so it will be useful as a debugging monitor. I'll have to find another display for I2C projects.Amended review:Two years later... I ordered again and got the right device this time. I've upped my rating from three to five stars because the new device works as expected. As before, the Adafruit SSD1306 library works, this time with the I2C interface, with the address set to 0x3C. The only minor quibble I have is that the four pin header was already soldered to the board. I would have preferred empty through-holes.

A good price alternative to the adafruit version, but after about 2 weeks it died. First, every other line went dead, then after fiddling with it some, completely dead. I don't think I abused it physically though might have ran arduino app that left it's inputs floating for a while before switching back to the known working demo.

This is a great little display. It is half the price as the Adafruit version, uses fewer I/O pins, and uses the same libraries. The display is ever so slightly less bright, but it is not an issue at all unless you are directly this to comparing the Adafruit one.To get the display running, install the Adafruit_SSD1306 library from their website/github. For whatever reason, they decided to make the library in such a way that you have to edit the .h file. Look around line 55-57ish and comment out the 128_32 reference and uncomment the 128_64 line. My device came with an address of 0x3C which was different from the documentation. You can use the arduino wire scanner sketch which scans the I2C bus for all possible addresses. Change the main .ino sketch to the right address and you should be ready to rock.

The media could not be loaded.  I am very satisfied with this display. It was easy to set up, just four wires. It works well with the Arduino libraries. The video is of the ssd1306_128x64_i2c example sketch. (Note: I forgot to remove the shipping cover before this video was taken.)An excellent reference is “Adafruit GFX Graphics Library” at the learn.adafruit web site.

Ordered this OLED display and got a green heatsink instead, in a black bag marked as if.Guess they ran out and wanted to play a terse joke.Bad deal.
