RF Link Transmitter - 434MHz
354 units available with a short lead time.
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
Note: These modules operate on a common frequency without built-in IDs or pairing, so they will pick up ambient noise. Use a library like VirtualWire to implement filtering and reliable data encoding. Module colour may vary (blue or green) — functionality is identical.
Ideal For
- Simple one-way wireless data links
- Remote sensor data transmission
- Learning RF communication basics
- Wireless trigger and control projects
