thanks for the pinout , but still i don't know which is RTC and which is CTS ?
another thing is i will connect a bluetooth module to the microcontroller and i will connect it to the serial of the microcontroller , so i know which pins to connect on both except for the +5v on the microcontroller , does it mean that i will get external voltage source ( 5v ) and connect it to pin 5 and not connecting the batteries to the microcontroller ?
thx fowlerm for the useful info .
if anyone wants to take a look at the bluetooth module i'm connecting ,, here it is
