I have a replica of nanowii , made from arduino pro micro 32u4 , mpu6050 and hmc5883 . Since now i had the aux2 connected on RX pin , but i bought a bluetooth dongle which connects on RX and TX pins .
So ... can i move the pin of aux 2 ? ( don't tell me about d17 because i can't see that pin on arduino pro micro )
If i can't move aux2 , now my question is: the arduino support aux3/aux4 ? If yes , which are those pins ?
