The VELLEMAN RX433N 433MHz Receiver Module Kit is a compact, high-sensitivity RF receiver designed for reliable wireless communication in remote control, telemetry, home automation, and DIY electronics projects. Operating on the licence-free 433MHz ISM frequency band, this receiver provides dependable long-range performance while remaining easy to integrate into custom electronic systems.
Designed for plug-and-play operation, the RX433N requires no manual adjustments or tuning, allowing it to be installed quickly into new or existing RF applications. Its stable output circuitry ensures consistent signal reception, making it suitable for both hobby and professional wireless control systems.
Using ASK (Amplitude Shift Keying) modulation, the receiver is compatible with many standard 433MHz transmitters and remote-control systems. With a high receiver sensitivity of -106dBm, the module is capable of receiving signals over distances of up to 200 metres in open-air conditions, depending on antenna design and environmental factors.
The module provides both a digital output for direct decoding by microcontrollers and logic circuits, as well as a linear output for applications requiring analogue signal processing or custom decoding. This flexibility makes the RX433N suitable for a wide range of wireless communication projects.
Operating from a 4.5V to 5.5V DC supply, the receiver integrates easily with popular microcontroller platforms including Arduino , PIC, AVR, and many other embedded systems. The compact PCB also includes clearly defined pin connections for power, ground, outputs, and an external antenna.
For optimum reception, the antenna input is designed for a 30-35cm wire antenna, allowing users to maximise communication range with a simple external antenna installation.
Typical applications include wireless remote controls, home automation systems, telemetry, wireless sensor networks, alarm systems, industrial monitoring, garage door controllers, robotics, model control, and countless other RF communication projects.
As a self-assembly electronics kit, the RX433N provides an excellent introduction to RF communications, wireless electronics, ASK modulation, and receiver design, making it suitable for students, makers, and electronics enthusiasts alike.
Whether building a wireless automation system or adding long-range RF communication to your latest project, the VELLEMAN RX433N 433MHz Receiver Module Kit delivers reliable performance, high sensitivity, and easy integration.
