Be careful to use a +3.3V Arduino, not a +5V one, as the TD modules are not 5V tolerant.

If not, you will need to insert voltage level converters in between, this can be as simple as a voltage divider on the modules's RX pin to bring down the voltage to a +3.3V-compatible level, the TX output from the module should be compatible with +5V input logic levels as-is.

Of course, you need to connect GND.

You can then control the TD RF module from the Arduino buy using a serial communication @ 9600 bps, 8 bit, 1 stop bit, no parity, no flow control.
