HiLetgo 0.95" Inch 7 Pin Colorful 65K SPI OLED Display Module SSD1331 96 * 64 Resolution for Arduino 51 STM32

This is a very good replacement for SSD1306 monochromatic OLED, even if it has a bit lower horizontal resolution. I clock SPI line at 19 MHz provided by Silicon Labs ARM micro-controller board, so the display image appears practically immediately. Currently the display is used for games development.

The media could not be loaded. Wrestled with this for a while then using advice from another reviewer, got it to work on an ESP32.1. RandomNerdTutorials to get your ESP32 to work.2. Added Libraries to IDE: Adafruit GFX and Adafruit Adafruit SSD13313. File --> Examples (from Custom Libraries) -->> Adafruit SSD 1331 OLED.... --> test4. Then changed the '#define' pins to: sckl (SCL) 22; mosi (SDA) 21; cs(CS) 5; rst (RES) 17; dc (DC) 165. 'Selected (removed //) from the command labelled Option 1:6. 'De-Select (added //) in front of the Option 2 commandthen plugged the SSD 1331 into the proper pins, uploaded the sketch and it works great. It's sharper in real life than on the attached video.I think you could do about the same thing to get it to work on an ESP8266 but I think you also need the #include <SPI.h> instruction. I'm pretty sure the SPI stuff loads with ESP32 but you have to specify it for an ESP8266.

This review is for HiLetgo 0.95" Inch 65K SPI OLED display.In term of hardware, the oled display has seven pins in total and five of the pins are used for the SPI interface.In term of software, if you plan use Arduino IDE, Adafruit has good driver support on this. Just search for "SSD1331" under library manager, you can install the driver easily. The nice thing about this driver is that it supports software SPI meaning that you can use any pins for the SPI interface. Of course, it will be slower than hardware SPI. However, for the sake of sanity test of this color OLED display, I just want to make the wire connections as easy as possible.Initially, when I received the display, I was worry that the screen is too small, but it turns out both color and text from the display are very sharp and crispy. Due to the high contrast, the viewing distance is quite good despite the screen size is only 0.95 inch. It also has wide angle range of display. I would highly recommend this color display for any project that requires a small color display (e.g. wearable, IoT).

Using with Arduino. It initially didn't work. While I was fiddling around with it, it flickered. Investigating further, I found that it would work if I firmly held the flex cable against the PCB. Looks like a bad solder joint between the flex cable and the PCB. While it's on, though, it's a nice display. Very bright.I decided to take a chance and retouch the solder. It seems to work OK now, but I really shouldn't have to do this. Knock off 2 stars for quality control.

I bought this and an ESP8266 controller, both from HiLetgo to build an alarm clock that is time synchronized to an NTP server.The instructions provided by HiLetgo on Amazon for the ESP8266 https://smile.amazon.com/gp/product/B010N1SPRK got me going very quickly, the only part I had to change was step 3 where it said use: esp8266com_index.json. This URL periodically seems to go off line, and was unavailable when I was setting up, so instead I downloaded the source, and used that locally.Then I added this oled display from HiLetgo and ran an example sketch to display wifi networks.The colors are bright and clear - and it seems to run fine from the onboard 3.3v supply provided by the ESP8266 controller.

A tiny color OLED? What's not to love. This thing will work with virtually any microcontroller, as programming libraries are widely available.OLEDs have the distinct advantage of using power only for the pixels that are illuminated, so you may be able to save battery power with this. Of course, an e-paper display would be even better, power-wise, if you can cope with the very slow refresh rate. But color is just SO nice to make it quick and easy to draw your eye to a particular reading, and if it's flashing red- go turn off that boiler that you're monitoring (well, maybe don't use it for that).Get this one here on Amazon, don't wait for the slow boat.

The media could not be loaded. Got this display at a great price. Was easy to set up and use. The resolution is great for text and small graphics. Worked on first test with the sample for the Arduino microcontroller.

The media could not be loaded. Until fairly recently OLED screens were black&white. Now, full colour is possible with this screen. It's clear, vibrant and simply works.Ucglib and Adafruit libraries work without issue on this SPI screen. It has been tested on an Arduino Nano, Arduino Uno and Arduino Esplora, running faultlessly on all 3. The Esplora only has a 5V VCC output, no problem, the screen runs on 3.3V or 5V.It's a really good, well made product.See the video for various tests and a cheeky Halloween extra.
