The Long Range RF Transmitter and Receiver kit from Seeed Studio consists of one transmitter and one receiver and is useful for remote control projects that don't require two-way communication. To attach one of these modules to a microcontroller you need to supply power and 4 digital data lines, so it's light in terms of GPIO pins.
