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

Even though I knew the dimensions of these displays, I was still surprised at how small they are (see pictures for relative size compared to Arduino PRO Micro). However, they work great and are very bright (mine is 5V) and the size is just right for smaller projects. Wiring was easy (VCC, GND, SDA and SCL). I used the Adafruit Arduino libraries (Adafruit_GFX and Adafruit_SSD1306) and her sketch worked right away. At $5.00 each they are a great value. Highly recommended.

This review is for "0.91 inch white" - I've bought two kits and am using them to prototype an Arduino GPS speedometer project . I use it with the Adafruit_SSD1306 library and their font FreeMonoBold24pt7b for numbers, fills the screen and looks great. My soldering skills are poor and when I tried to desolder the connectors I put on a board to re-solder some wires I burned the trace but that's my fault. I have bought two more packs, I really like these displays so far. I will test it at the…

This is an amazing tiny high resolution OLED display for any of your microcontroller projects. It uses the very popular I2C bus and runs on an SSD1306 display driver. The resolution of 128 x 32 pixels ensures crisp and clear text. I am very happy with it. This is a really good way to add a very compact LCD to your project. No need to add a big bulky backlit LCD, use this one instead! I have bought many different things from MakerFocus and their products are always good. If you need to use this…

I am using this with Sparkfun ESP8266 Thing. Works perfectly! Nice little, crisp and inexpensive little display. I'm using it with the u8g2 library and I'm only interested in a text display with no graphics at the moment, so I'm using the light text version of the u8x8 library/API and calling the display U8X8_SSD1306_128X32_UNIVISION_HW_I2C. This simple library is very easy to use - just remember to put pull-up resistors on SCL/SDA if you don't already have an I2C device on the bus that does…

One screen worked very well to be honest I overstretched it fiddling with my circuit. The second worked at 5 volts for 5 seconds but then went out, brightened, dimmed, brightened then turned off but got very hot. After researching a lot of online information, reviews, FAQs etc. it seems that 4k7 resistors are not required for the Arduino Pro Mini (clone) as they have internal pull-up resistors for pins A4 and A5 if they are not mounted directly to finish . Pencils. In any case, it also doesn't…

I was able to get these displays up and running in under 10 minutes! Below is a quick guide. The display is bright and even at 3.3V and 5.0V. Contrast is perfect as you would expect from OLED. color blue or sky blue; looks like the old blue VFDs that were popular in the 80's and 90's. These modules are very thin - 3.7 mm! In photos they look like fixed format displays with 7 segment digits and multiple displays, but they are dot matrix displays (128 x 32 pixels). You can program each pixel to…

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…

Update 1: I'm about to find out why I'm still having problems with this device. After posting, I found that at least for the NodeMCU8266, contrary to my original assessment, pull-up resistors might not be needed. (In fact, the schematic diagram in the image listing shows that they are built in.) I have confirmed that the device can also work with the Arduino Uno, so as described it is both 3v3 and 5v compatible. However, Uno only works when the 4.7 kΩ resistor pulls the SCL line high. Strange…
