A simple 434 MHz ASK RF transmitter module for creating basic one-way wireless data links. Breadboard-friendly and easy to pair with a microcontroller, this transmitter works with compatible 434 MHz receiver modules to send data wirelessly at up to 4,800 bps over distances up to 500 ft in ideal conditions.
Since this is a transmitter only, you'll need a separate 434 MHz receiver to complete the link. For bidirectional communication, two transmitter/receiver pairs at different frequencies are required.
Key Features
- 434 MHz Frequency – ISM band operation
- Up to 500 ft Range – Under ideal, line-of-sight conditions
- 4,800 bps Data Rate – Suitable for low-bandwidth sensor data
- 5 V Supply Voltage – Standard microcontroller compatible
- Breadboard-Friendly – Fits directly into standard breadboards
Ideal For
- Simple one-way wireless data links
- Remote sensor data transmission
- Learning RF communication basics
- Wireless trigger and control projects
Package Contents
- 1× RF Link Transmitter Module – 434 MHz

Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
