Having developed and tested a project using an Arduino Uno, I would now like to upload it to an Arduino Pro Mini (5V, 328, 16MHz) for semi-permanent, long-term use, but I can't get any sign of life from the Pro Mini.
I'm using the latest Arduino IDE (v1.6.0 with Java 6, on Mac OS X Mavericks), and I've got a USB 2.0 to TTL UART 6PIN CP2102 Module Serial Converter to connect the Pro Mini to the Mac, and I've selected Tools —> Board —> Arduino Pro or Pro Mini (5V, 16MHz) w/ ATmega328.
The problem is that I don't see a suitable serial port in the list. When I plug in the Arduino Uno, "/dev/tty.usbmodem1421" immediately pops up in the Tools —> Serial Port menu, but I don't see anything similar with the Mini Pro.
The problem is probably in the connection between the USB/TTL converter and the Mini Pro, so my question is: which pins should connect to which?
FWIW the USB/TTL converter was supplied with a 5-core (not 6-core) cable to connect its 6 pins.
So do I connect Tx—>Tx and Rx->Rx, or should they be crossed over? It's fairly clear that "5V" connects to "Vcc" and "GND" goes to "GND", but what about CTS and DTR?
Also FWIW, I have googled this, and I have read a number of other posts and answers on StackExchange, but the fact that I'm here writing my question means that I'm still stuck. Any and all constructive suggestions will be appreciated. Thanks!
