HiLetgo1.5" SH1107 128x128 OLED Display Module 1.5 Inch IIC I2C 4 Pin OLED Screen LCD Display White

I got the SPI version, and it seems to work exactly as advertised. Note that this uses a different chip (SH1107) from most of the 128x64 displays that all the howtos out there on the net usually demonstrate, so you will need a different driver for it. However, I had no problem using a MicroPython sh1107 driver with this display, and got it up and running right away...

I have used a lot of OLED displays, from HiLetgo and other brands, without any problems. I know you have to find the right library, and wire them correctly, of course, but these wouldn't even respond to an I2C scanner program I've been using for years. Every other I2C OLED I have works fine with it - they are all immediately recognized as a device at a particular address - but these won't even do that. I suspect they are defective since every other I2C OLED I have has a square solder pad for ground and round for all 3 others. These have Vcc as the square pad and round for the rest. I can't find a way to get info from HiLetgo, so these are going back.

Worked perfect for me. One thing to keep in mind about all of these tiny displays is that they are extremely fragile. Very brittle where the ribbon cable connects to the screen. They are a bit pricey for this type of monochrome display but have sharp text images.
