RF 315MHz module RF Transmitter Receiver Module 315MHz Wireless Link Kit + 315MHz Spring Antenna for Arduino

• Working voltage: 3V ~ 12V
• Working current: 20mA ~ 28mA
• Standby current: 0mA
• Working frequency: 315MHz

Description :

The kit includes one pair of transmitter and receiver modules and one pair of spring antennas for increasing the communication distance. And the frequency is 315MHz. It is very popular for remote control systems, such as Remote control rolling gates, smart car, smart home, etc. And the transmission distance: 3m (maximum) at VCC = 5V without additional antenna. When the spring antennas are soldered to transmitter and receiver module, the transmission distance can be increased to 5 meters. The supply voltage is larger, the transmission distance farther.
