The Parallax 433 MHz RF Transceiver allows users to easily send serial data, robot control data or other information wirelessly. Reliable wireless communication is as effortless as sending serial data. The power-down (PDN) pin may be used to place the module into a low power state (active low), or left floating (it is pulled high on the module).


  • High-speed data transfer rates (1200 ~ 9600 baud)
  • SIP header allows for ease of use with breadboards
  • Compatible with most microcontrollers including the Propeller chip and all BASIC Stamp models
  • As easy to use as simple SEROUT/SERIN PBASIC instructions
