How do I wire it to an Arduino?
Connect the module's TXD to the Arduino RX pin and the module's RXD to the Arduino TX pin, with GND to GND. Power the module as its datasheet specifies, and disconnect the serial pins while uploading sketches.
Can I connect it directly to a 5 V board?
Check the module's logic voltage in its datasheet first. If its RX input is 3.3 V logic, use a level shifter or a voltage divider on the line from the 5 V board to avoid damaging it.
