RF TX-RX ASK 433MHZ Module

Description

RF TX-RX ASK 433MHz Module

This compact wireless transmitter and receiver pair is the perfect solution for adding basic one-way wireless control to your Arduino, ESP32, or other microcontroller projects . It uses ASK (Amplitude Shift Keying) modulation, making it ideal for simple remote control, automation, and alarm systems .

Module Specifications

Transmitter Module

Receiver Module

Receiver Module Model: XY-MK-5V or MX-05V 
Transmitter Module Model: MX-FS-03V 

Perfect For

• Remote control switches and automation 

• Wireless security alarms 

• Garage door openers 

• Arduino, ESP32, and Raspberry Pi projects 

Quick Usage Guide

1. Transmitter – Connect VCC (3V–12V), GND, and DATA to your microcontroller. Use the VirtualWire library for reliable communication .

2. Receiver – Connect VCC (5V), GND, and DATA. The DATA pin outputs TTL signals .

3. Antenna – Solder a ~25 cm wire to the antenna pad on both modules to maximize range .

4. Compatibility – Works with common ASK encoder/decoder ICs like PT2262/PT2272 if needed .

Note

This kit is designed for simple on/off remote control, not high-speed continuous data transmission. To avoid interference, limit transmissions to a few commands per second . Use with a decoder IC (like PT2272) or a software decoding library for reliable operation . Always check your wiring polarity before powering up to avoid damage.
