Need a simple wireless connection when Wi-Fi and Bluetooth aren’t available? This 433MHz RF module set is a cost-effective solution for short-range, one-way data transmission. Commonly used for remote control applications, it includes an FS1000A transmitter and a matching receiver operating at 433 MHz.

The transmitter sends serial data wirelessly through an external antenna, while the receiver captures the signal at the same frequency for processing. Data rates can range from 1kbps to 10kbps, with a typical range of up to 100 meters (depending on antenna design, supply voltage, and environment).

Quick Specs:

• Frequency: 433MHz
• Modulation: ASK
• Data Rate: 1–10kbps
• Range: Up to 100m (conditions dependent)
• Transmitter Input Voltage: 3–12V (higher voltage = more power)
• Receiver Data Output: High = ½ Vcc, Low = 0.7V
• Pins:
  • DATA – Input data to transmit
  • VCC – 3.5V to 12V supply
  • GND – Ground
  • ANT – External antenna connection

Applications:

• Remote control systems
• Arduino-to-Arduino data transmission
• Wireless sensor networks

Package Includes:

• 1x 433MHz RF Transmitter
• 1x 433MHz RF Receiver
