Review on IZOKEE 0.96'' I2C IIC 12864 OLED LCD Display Shield Board Module 4 Pin Pack (3pcs, White-IIC) for Arduino Raspberry Pi: Review & Buying Guide by Chris Graves

These little displays are great! FYI to anyone trying to implement them, the documentation is wrong. I am using them with an Arduino Nano V3, so the SDA pin is A4 and SCL is A5. For I2C, in the code I've seen, the I2C address is documented as 0x3D. That is not right. It didn't work on my Nano. Using an I2C scanner, the correct address for me was 0x3C:display.begin(SSD1306_SWITCHCAPVCC, 0x3C); Once I figure it out, it's kinda like a champ!
