💙 0.91 Inch Blue I2C OLED Display Module for 5 Pieces, with DC 3.3V~5V I2C OLED Screen Driver Review

This works well when I group my pis as the height is about what I would have between pis. Installing the Adafruit library took a bit of fiddling, and as you can see the image shows some additional control characters from the example, but using it I'll make sure the text more closely matches what I want. I had to omit the contract in the picture because it's a conspicuous little thing and otherwise it would blur the picture. I didn't mind putting headers. While the connectors are fine at this…

no connectors soldered to the boards. I had to go out in the rain to get the $12 headers to solder them myself, adding about 80% to the cost of the item. Also there is no manual for this product. The product claims to support 3.3-5V as stated in the title but actually only supports 5V. I spent a couple of hours trying to figure this out. The product works, but it is very cumbersome to get it working.

I got exactly what I expected: 5 very small i2c OLED displays and 5 (4 pin pins for breadboard). I am very happy with the product, bright, easy to use and just what I needed! Anyone who complained about the tiny displays obviously didn't read the description. They are great for the new Raspberry Pi Pico! Haven't received mine yet, so I'll have to play around with the Raspberry Pi 4 first.

A little nervous about buying these due to the price but took a risk. I really liked the screen printing. Nice light blue for chalkboards and bright white for lettering. Each OLED came with a header. They sit very tight. After connecting the connectors to the board without soldering, I was able to hold the connector board upside down and they didn't come loose. (still new so don't judge me), soldered to 433 soldered perfectly. There is no burn-in, no deformation or discoloration on the board…
