 If you are using the 128*32 small displays, then you will be using separate I2C busses and having the same address for each OLED does not matter. ​ If you are using the 128*32 small displays, then you will be using separate I2C busses and having the same address for each OLED does not matter. ​

 (For some reason, the displays have the address printed as '​0x78'​ and '​0x7A',​ but I will refer to these as '​60d'​ and '​61d',​ as this how the code "​sees"​ them.) (For some reason, the displays have the address printed as '​0x78'​ and '​0x7A',​ but I will refer to these as '​60d'​ and '​61d',​ as this how the code "​sees"​ them.)
 The display on the left has been adjusted to '​61d'​ Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light. The display on the left has been adjusted to '​61d'​ Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light.
