433 mhz Rx Tx Module

The kit features a compact, high-speed Transmitter (FS1000A) and a high-sensitivity Receiver. Using ASK (Amplitude Shift Keying) modulation, these modules allow for easy "wireless serial" communication over distances that typically range from 20 to 100 meters, depending on the input voltage and antenna quality. Key Technical Specifications Operating Voltage: * Transmitter: 3.5V to 12V DC (Higher voltage increases transmission range). Receiver: 5V DC. Frequency Stability: High-precision SAW resonator ensures minimal frequency drift. Data Rate: Supports speeds up to 4KB/s, ideal for sensor data and command signals. Compact Form Factor: Small footprint allows for easy integration into breadboards or custom PCBs. Minimal Interference: Designed for the license-free ISM band, providing a reliable link for low-duty cycle applications.
