SYN480R 433MHZ ASK/OOK Wireless Receiver Module

SYN480R 433MHZ ASK/OOK Wireless Receiver Module is a high-performance, ultra-compact superheterodyne wireless receiver designed for reliable short-range data communication in the 433.92 MHz ISM band. This module integrates the specialized SYN480R chip, which offers superior sensitivity and interference rejection compared to basic regenerative receiver designs. Consequently, it provides a significantly more stable connection and longer range for remote control systems and wireless sensor networks. Engineers often pair this module with ASK (Amplitude Shift Keying) or OOK (On-Off Keying) transmitters to create robust wireless links for microcontrollers like Arduino, ESP8266, and PIC. Furthermore, the module operates efficiently at low voltages, making it an ideal choice for battery-powered applications where power conservation is critical. Therefore, you can achieve professional-grade wireless data reception with minimal external circuitry by incorporating this module into your next RF project.

Key Features:
