The 315MHz RF Transmitter & Receiver Wireless Module sends and receives radio signals at 315MHz without any wire between the two boards. The signal travels up to 100 meters in open space. The 315 MHz RF module works with an encoder-decoder IC (a chip that packages digital signals) for clean data transfer.
The RF transmitter and receiver module runs its transmitter on 3V to 12V DC, giving flexibility with different power sources. One detail most beginners miss: the 315MHz band is shared with many other consumer devices, so interference in crowded areas is a real possibility. The 4.8 kbps data rate handles simple on-off commands well but is not suited for complex data.
The 315MHz RF transmitter receiver module pairs with Arduino and ESP8266 boards. Students and hobbyists building remote control projects use it regularly. Connect transmitter and receiver boards, add an encoder-decoder pair, and you are ready. StemVolt offers fast and reliable delivery of across India with trusted service support.
