I am working on a project using an Arduino pro that I got off of Sparkfun. This is the exact board that I am using Arduino Pro 328 - 5V/16MHz - DEV-10915 - SparkFun Electronics. In my project, I am using the i2c bus to drive a LED matrix on my prototype. I would like to keep using the i2c bus in the pro board but before I go soldering wires I want to double check that I am soldering the wires correctly.
If I am reading the schematic (https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/Arduino-Pro-v14.pdf) correctly, analog pin 4 is the SDA connection for the i2c bus and analog pin 5 is the SCL connection for the i2c bus. Is this correct?
