RF Transmitter Receiver Module 433MHz Wireless Link Kit for Arduino

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 433MHz. It is very popular for remote control systems, such as Remote control rolling gates, smart car, smart home, etc.About the transmitter module (square shape):- Compatible with Arduino;- Arduino Library: VirtualWire;- Operating voltage: 3.5~12V DC;- Working frequency: 433MHz;- Transfer rate: 4KB/S (max);- Transmission distance: 3 m (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. About receiver module (rectangle shape):- Compatible with Arduino;- Arduino Library: VirtualWire;- Operating voltage: 4.75~5.25V DC;- Working frequency: 433MHz;- Quiescent Current: 4mA;- Great for DIY project.GeneralModelN/AQuantity1 setMaterialPCB + alloySpecificationFrequency433MHzWorking Voltage 5VWorking Current4mAEnglish Manual / SpecYesDownload Link http://pan.baidu.com/s/1o667XUEPacking List1 x 433MHz RF transmitter module1 x 433MHz RF receiver module2 x 433MHz spring antennas (2.7cm)Package Weight:0.014kg (0.031lb)Package Size:6cm x 5.8cm x 2.8cm (2.36in x 1.97in x 0.79in)
