I got my self a Sparkfun RTC breakeout board, contrary to their wiring example it only seem to work with SDA wired to A4 and SCL to A5, is it possible to wire it opposit? With A1 and A2 set for power and ground it would make it possible to plug the RTC breakeout straight into the pins. I understand…

Sorry, I2C is a hardware feature bound to those pins. A5 = SCL, A4 = SDA.
