VGDD79S433N0S1

Component

433 MHzLLCC68LoRaFSKsub-GHzSPI50 Ω antenna+22 dBm

VGdd79S433N0S1 is a compact 433 MHz LLCC68-based LoRa/(G)FSK wireless module for low-power sub-GHz links. It provides SPI control, a 50 Ω antenna connection, and output power up to +22 dBm.

Best for

  • 433 MHz low-power wireless sensor links
  • LoRa-based remote monitoring
  • Smart metering and asset tracking
  • Industrial and agricultural telemetry

Avoid if

  • Applications requiring a frequency band other than 433 MHz
  • Designs without controlled RF layout or a suitable 50 Ω antenna
  • Projects requiring documented compliance status from the supplied sources

Check before use

  • Verify regional 433 MHz radio regulations and permitted transmit power
  • Confirm antenna impedance and tune the matching network if needed
  • Confirm supported LoRa bandwidth and spreading-factor combinations
  • Avoid 32 MHz crystal harmonic frequency points where receiver sensitivity may degrade
