Review on 🔹 MakerFocus 6pcs I2C OLED Display Module 0.91 Inch Blue SSD1306 OLED Screen Driver 3.3V~5V for Arduino by Marcus Munoz

These things are tiny! This worked well for me as the projects I did had to be skipped when things were going well. I used the Adafruit SSD 1306 libraries and they worked great. They're thin and light. They're really overkill for the Adafruit library checks. Basically, "Hello World" doesn't exist, so just do a Google search for the "Hello World" library example to get a basic starting point. To rotate the display 180 degrees, also enter display.setRotation(2); in the setting. The main usage of these libraries is: .display.display();display.clearDisplay();display.setTextSize(1-3);display.setCursor(0,0); // origin textdisplay.print("blah");display.println("-added to the last word blah, then newline"); In terms of hardware, the displays are nice and small. If you think of your breadboard, they are 4 rows high and about 12 slots wide. (That's the whole board.) The voltage range is impressive and seems to work below 3.3V, but I'm using it at 4.5V and no problem. (Mostly 5V from the wall but through the diode on the Arduino). It takes about 5mA. I bet that with a watchdog and some adjustment you could run an entire professional mini-project at less than 3mA standby while still having the display working. The update time on the display is very fast and the cameras do not detect multiplexing/flickering. They didn't come with leads, but the through holes are very well made and accept solder well. The holes are quite dense and therefore durable. They'll be hard to desolder afterward, so google some pin removal tricks to make your life easier! If this review was helpful to you, please rate it! :DI think a lot of people had these questions.
