433MHz RF Wireless Transmitter Receiver Link Kit for Arduino

Cut the wires and communicate wirelessly. This 433MHz RF Link Kit is the most affordable and straightforward way to add wireless capability to your electronics. Consisting of a compact transmitter module and a matching receiver, it allows two Arduino boards to "talk" to each other without physical cables. It is the go-to solution for building simple remote controls, weather stations, and alarm systems that require reliable data transmission over short to medium distances.

• COMPLETE TX/RX PAIR: Includes both the wireless transmitter (small square) and receiver (long rectangle) modules, giving you a full communication link right out of the box.
  
  
• AM / ASK MODULATION: Utilizes stable Amplitude Shift Keying (ASK) technology, making it incredibly easy to interface with microcontrollers using simple digital pins.
  
  
• LIBRARY SUPPORT: Fully compatible with the popular VirtualWire and RadioHead libraries, allowing you to send text strings and sensor data with just a few lines of code.
  
  
• EXTENDABLE RANGE: While compact, the range can be significantly boosted (up to 100m in open air) simply by soldering a 17cm wire antenna to the ANT pads.
  
  
• LOW POWER OPERATION: The transmitter draws virtually zero power when not sending data, making it ideal for battery-operated remote sensor nodes and key fobs.
