DIYmalls 1,3' inch OLED Display Screen Module I2C 4pin 128x64 SH - 1106 3.3V-5V IIC Adres 0x3C Wit voor Arduino 2560 ESP8266 ESP32 (Pack van 3)

This is a great little screen for the Arduino. It's only tiny but it looks super sharp and I'm quite impressed by the quality. It comes in a pretty unassuming box but everything is well protected inside. It took me a bit to figure out how it all worked but once I'd worked it out it all works really well, and I'm really happy with it!

It works fine, but I was quite dissapointed it isn't breadboard friendly because of all the components in the back, mainly the inductance coil.Other than that took me about 15 minutes to figure out how to use the U8Glib library.I am still learning, will take me sometime understanding how it works fully.

Die drei kleinen OLED-Bildschirme sind jeweils in Einweg-ESD-Schutzfolien verpackt.Für die Benutzung muss die U8G2 Bibliothek in der Arduino IDE installiert werden.Ein funktionierender Hello-World Code findet sich schnell mit Google. Die I2C Adresse entsprechend anpassen, hochladen auf den ESP oder Arduino und es funktioniert.Das Display ist scharf, dank OLED leuchten nur die Pixel die etwas darstellen, dadurch hat man einen super Kontrast.Ich finde die etwas große Spule auf der Rückseite nicht so toll, dadurch ist die Montage auf normalen Breadboards erschwert / das Display generell etwas höher als man es vielleicht von anderen OLEDs Mini-Bildschirmen kennt.

So, I added the U8G2 library to my Arduino IDE (using the manage libraries function in the IDE).It installed fine.I then loaded up the "Hello World" example, and found the line that matches the one in the Amazon description. For me, the line number was 79 instead of 72. Just make sure you find the line that matches the code, not the line number.I wired it up as shown in the pictures, but specifically A4 for SDA and A5 for SCL. The other wires, to power and ground, as printed on the board.Compiled the code and it worked immediately!Also, I tried the "GraphicsTest" example that comes with the U8G2 library, which is perfect, because it shows all the main functions for drawing text, shapes, bitmap xoring, etc.Overall, was easy to get started and the GraphcisTest example showed me basically everything I need to know.The only catch I found was that unicode emojis show up as "?" on the screen. The Graphics test tries to use them in one of it's examples. Oh well, I wasn't planning on using those (didn't even know some screens included them).It's hard to see in my pictures, but the pixels are super crisp, well-defined little squares. There is a noticeable gap between each pixel, so you can see a "screen door effect" but it looks cool.Overall, neat little screen.

This is great for adding a little display to remote esp32 sensor setups. I use esp32 with proximity detection around our place and having a screen to show a little info at the same time is great. It's never going to replace our smart home control displays but in places where we don't have a larger touch display we can use these and show something useful at the same time. Perfect.
