433 MHz RF Transceiver




$39.99 ea.

This easy to use and low cost module is capable of sending and receiving serial data wirelessly between microcontrollers or to a PC. The low power consumption makes this module ideal for use in battery powered applications.

Description [Hide]

This module sends and receives data by AM or CPCA modulation, thus offering a higher average output power which extends its range. This module is equipped with an RSSI feature that can be utilized to improve power efficiency by waking up circuitry only when an external signal is detected. 3.3 to 5.0VDC; Transmit: 12mA, Receive: 6.1 mA, Power Down:11.5 uA


  • High speed data transfer rates: 1200-9600 bps
  • Asynchronous serial data (TTL/CMOS compatible)
  • SIP header allows for ease of use with breadboards
  • Compatible with most microcontrollers including the Propeller chip and all BASIC Stamp models
  • Power-down mode for conservative energy usage (longer battery life)
  • Line of sight range up to 250 feet (depending on operating conditions)

Application Ideas:

  • Remote controlled Boe-Bot robot
  • Wireless data acquisition
  • Remote signal beacon for adventure seekers
  • Remote industrial monitoring
  • Lighting control
  • Keyless entry

Key Specifications:

  • Power requirements: 3.3 VDC to 5.0 VDC
  • Communication: Asynchronous Serial @ 1200-9600 baud 
  • Dimensions (With Antenna): 3.82 x 0.94 x 0.41 in (97 x 24 x 10.5 mm)
  • Operating temp range: +32°F to +158°F (0°C to +70°C)
