433 MHzSi4438sub-GHz RF moduleSPIGFSKFSKOOK20 dBm

VG5549S433N1S1 is a compact 433 MHz Si4438-based sub-GHz RF module for SPI-controlled bidirectional wireless links, with configurable modulation, rate, bandwidth, and output power.

Best for

  • 433 MHz wireless metering
  • Industrial wireless data collection
  • Remote monitoring and control
  • Sub-GHz sensor networks

Avoid if

  • A pre-certified radio module is required and certification evidence must be documented
  • The system requires a frequency outside the 433 MHz module variant

Check before use

  • Confirm local regulatory requirements for the intended 433 MHz operating channel and transmit power
  • Validate the final antenna and 50 Ω PCB feed with the assembled enclosure
  • Confirm RF GPIO configuration generated by WDS
