Seeed 113990018 2KM Long Range RF Transmitter and Receiver Link Kits

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.
