Have you or anyone been able to get the spark fun Pro Micro to communicate?

I wired up 2, both TX/RX and pins 2-2 and 3-3 for SDA &  SCL

Of course, I edited the script to use pin 10 for the LEDs, since the Pro Micro doesn’t have a pin 13

In both cases, the sending Micro flashes the random counts of the LED, but in neither case does the receiving Micro show any signs of communication.
