You connect the Moteino/Arduino to the RPi using USB. Your code running on the RPi opens /dev/ttyUSB0 (or whatever it shows up as) and talks to the uC on the Moteino/Arduino like if it were using a true serial port (/dev/ttyUSB0 behaves like a true serial port for all intents and purposes). You don't have to use /dev/ttyAMA0 (the Broadcom UART) to talk to the Moteino/Arduino. In fact, you cannot because the Rx and Tx pins of the uC are connected to the FTDI chip, so USB is the only option to talk to an Arduino via serial (unless the Arduino is one of the recent generations that supports more than one serial port), in which you don't have to use USB and can use the RPi serial port directly.
