433 mhz Rf Module

The kit consists of two distinct components: a compact Transmitter and a high-sensitivity Receiver. Operating at the license-free 433MHz ISM band, it is designed for low-power consumption and seamless integration with platforms like Arduino, Raspberry Pi, and other IoT development boards. Key Technical Features Reliable Range: Achieve a transmission distance of 50–100 meters (depending on the environment and voltage), which can be further enhanced using the included spring antennas. Low Power Consumption: Optimized for battery-operated devices, drawing minimal current during standby and active transmission. Simple Interface: Uses a basic 4-pin header (VCC, Data, Ground, and Antenna) for straightforward "plug-and-play" wiring. Crystal-Stabilized Frequency: Features high-precision crystal oscillators (marked 6.7458T and 13.560) to ensure frequency stability and reduce signal drift. Amplitude Shift Keying (ASK): Utilizes ASK modulation for robust data transfer, making it highly resistant to interference in urban environments.
