Component

433 MHzLLCC68LoRaFSKSub-GHzSPIWireless module16-pad SMD

VGdd79S433N0M1 is a compact 433 MHz LLCC68 LoRa/(G)FSK transceiver module for low-power sub-GHz wireless nodes using SPI control.

Best for

  • 433 MHz battery-powered sensor nodes
  • Long-range sub-GHz telemetry
  • SPI-controlled LoRa or FSK radio designs

Avoid if

  • A fully certified end-product radio is required without system-level certification work
  • The design cannot provide a controlled 50 ohm antenna path
  • A 5 V-only digital interface is required

Check before use

  • Verify the permitted 433 MHz frequency plan and transmit power for the target region
  • Provide sufficient supply-current margin for +22 dBm transmission
  • Configure DIO2 as RF switch control
  • Validate antenna matching and RF layout on the final enclosure
