SX1278ATR4-GC

Chip Resistor - Surface Mount

433 MHzSX1278LoRaSPI20 dBmRF module

SX1278ATR4-GC is a 433 MHz SX1278-based RF module for SPI-controlled LoRa and conventional sub-GHz modulation modes. It supports up to 20 dBm transmit power and uses an external approximately 50 Ohm antenna.

Best for

  • 433 MHz low-data-rate radio links
  • wireless sensor data collection
  • SPI-controlled embedded RF designs

Avoid if

  • A certified protocol module is required
  • Antenna and RF layout cannot be controlled
  • Required compliance or lifecycle information must be documented

Check before use

  • Confirm regional frequency regulations
  • Validate antenna impedance and installation
  • Review SX1278 register settings and interrupt mapping
