🔵 Teyleten Robot SSH1106 OLED Display Module 128x64 1.3 inch I2C IIC Serial OLED Module for Raspberry Pi and Microcontroller (Blue Light) - 2pcs Review

When I tried this product, I was amazed at how versatile it was for my computer projects. The microcontroller has a fantastic display that's easy to use, and it's compatible with many coding languages. I love the endless possibilities with this microcontroller, and it has helped me create some exciting new projects. However, I did find the initial setup confusing, and it took some time to get everything up and running smoothly.

The I2C address printed on the board was 0x78. The other address you could enable with a jumper was 0x7A. But neither one nor the other worked. I ran i2c_scanner and it was indeed 0x3C. Not the end of the world, but I'm sure some will be upset about it. The display looks nice and bright. Not as fast as SPI, which is fine. No complaints other than the address question.

The main complaint I have is that junk appears along the right side of the display (as shown in the picture). Another problem is that the functions available in the ACROBOTIC SSD1306 library are quite limited, making it almost impossible to generate larger characters. Because the drawBitmap function can only be used once to create a bitmap, trying to use bitmap symbols is not possible.
