Hosyond 5 Pcs 0.96 Inch OLED I2C Display Module 128x64 Pixel Screen IIC Serial Mini Self-Luminous Board Compatible With Arduino Raspberry PI (Blue and Yellow)

Love It i use it as my 3D printer Mini Screen

Good quality OLED screens. Tested they will run normally at a voltage as low as 3.5v without any loss of brightness. Each OLED screen is nicely packaged in its own protective little plastic box.

Worked great.

I've used these displays on several other projects, so I selected them again. The price is good, but not great. They work exactly as advertised. Note that some of the displays are monochrome (bluish green), but others have a few lines at the top that emit yellowish light. I like the ones that have a few yellow lines as you can highlight a title of whatever it is you're displaying. The only complaint I have is that Amazon does not include detailed dimensions of the part. I had to search other 0.96" parts (also from Amazon) to get the dimensions I needed. I integrate the display into a 3D printed housing. To get the front of the display flush with the housing, I needed to provide relief around the panel for a good fit. So I need all the physical dimensions.

This product communicates over the I2c bus, and is at address 0x3c. The address is changeable with some soldering, but unless you really need to, dont risk it. You do not have the ability to change the color of the pixels, the top 16 rows of pixels are yellow, and the rest are blue. The protocol is SSD1306, and there are several libraries out there you can use. For me, I used a bare bones C library, but your use case may vary. I got this to work on a LePotato Libre computer SBC, and it also allowed me to use GPIO as well so that I can control some relays, read voltages coming back, and display a formatted display of the device it was monitoring. The mounting holes are smaller than the M2.5 used by Raspberry Pi boards, but just barely. M2 maybe? 1/16th? Anyway, its really small so keep that in mind when designing something to mount it to. The documentation referenced by the card inside links to a dropbox and the pdfs are all in Chinese, so if you are like me and dont read Chinese, you have to figure this out yourself. I2C bus, address 0x3c, SSD1306 protocol, 3-5 volt source from vcc and gnd, sda and sdc go 1:1 on the card too, no need to cross them like UART. Mounting holes are approx 2mm.
