5 Pieces I2C Display Module 0.91 Inch I2C OLED Display Module Blue I2C OLED Screen Driver DC 3.3V~5V(Blue Display Color)

Would have give 5 but one of them was cracked.

Is a copy of an Adafruit display and the Adafuit libs for Arduino work with this device. Just note, this is a very very tiny display. For reference the pins are 2.54mm pitch. Cant beat the price for what you get. Just note that I2C is slower than SPI, or high speed parallel so the refresh rate is low, but its still pretty quick.

not worth get something else trust

Worked well. The example code in Arduino IDE for the Adafruit SSD1306 Library worked and provided a start.

This is an awesome, tiny, high resolution OLED for any of your micro controller projects. It used the very common I2C bus, and runs on the SSD1306 display driver. 128x32 pixels gives you a nice sharp, crisp text output. Im very happy with these. This is a really good way to add a very compact LCD to your project. No need to add some big bulky backlit LED, go with this instead! I used the Adafruit SSD 1306 Libraries and they worked great. They are low power and bright. For the adafruit library examples, they really are over the top. There is no hello world essentially, so just do a google search for a hello world example for the libraries to get a basic starting point. Also, to rotate the display 180 Degrees, put in display. setRotation(2); in the setup. Basic usage for those libraries are.. display. display() ; display. clearDisplay() ; display. setTexSize(1-3) ; display. setCursor(0,0) ; // origin of text display. print(blah) display.println(-appended to last word blah, then new line ) ; As for the hardware, the displays are nice and small. If you think of your breadboard, they are 4 rows high, then about 12 slots wide. (Thats the entire board.) Voltage range is impressive and seems to operate at lower than 3.3, but Im running it on 4.5V and there are no problems. (Basically, 5v from the wall but through a diode on the arduino). It takes around 5ma. With a watch dog timer and adjustment I bet you could I get a whole pro mini project to run at under 3ma standby while keeping the display going. Refresh time on the display is very fast and cameras dont pick up any multiplexing/flicker. They did not come with headers, but the plated through holes are very well done and take solder well. The holes are pretty snug, which means its strong. It will be hard to desolder these after , so google some tricks on removing header pins to make your life easier!

Concuerda con la descripcion, funcionan perfectamente.

If you need a small display for your Seeed Studios, Adafruit, or Arduino Microcontroller or Raspberry Pi / Pico, this one is bright, 3v3 compatible, and easily driven with i2c using an SSD1306 library for Arduino/C or CircuitPython. 128x32 is enough to get four small lines of text for status reports or messages. I powered these with a Seeed Studio Xiao. I used the Adafruit Library. So compact you could make a wearable name-tag or display.

Good displays - all set to 0x3C i2c address. Came without pin headers soldered, which was perfect since I needed a locking connector, not header pins. The headers are in the bag so if you want them just need to solder them on. I hope more white displays are in stock soon!

there are no headers soldered to the boards. i had to go out in the rain to get headers for $12 to solder them myself which adds about 80% costs to the item. there is also no manual for this product. the product is supposed to support 3.3v to 5v as claimed in title, but in fact it only supports 5v. i wasted a couple hours to find this out. the product works but it is very inconvenient to make it work.

There is no documentation at all for these devices. It turns out that the Adafruit libraries work just fine IF you know that the IC2 address is 0x3C and change it in the examples. The brightness is just fine and they are quite cheap, but they are incredibly small.
