Get Arduino Nano Every I2C Pins
Gallery. I got some arduino nanos at really good price on amazon and wanted to connect a 7 segment led display with an i2c backpack. I too wasted hours and started suspecting ii'm looking in the wrong place so did a search for i2c nano problem that took me here.

I got some arduino nanos at really good price on amazon and wanted to connect a 7 segment led display with an i2c backpack. As mentioned earlier, arduino nano has 14 digital i/o pins that can be used either as digital input or output. The i2c communication is one out of three possible communication protocols, the arduino / esp8266 is able to communicate with other devices like oled displays, barometric pressure arduino nano.
How to solder header pins.
Maybe it is because many of the pinout diagrams for the nano have scl and sda on the wrong pins. I2c a4 (sda) and a5 (sca): The arduino nano is very much similar to the arduino uno. I see on arduino uno there is twice sda and sdl:
