How It Works
The RA-02 transmits and receives data using LoRa modulation. A compatible microcontroller communicates with the module through SPI and configures parameters such as frequency, spreading factor, bandwidth, and transmission power.
Two compatible LoRa devices can communicate when their radio settings match and their antennas and RF configurations are appropriate.
Compatibility & Usage Notes
-
Operate the module at its specified supply voltage and logic levels.
-
Use a suitable antenna for the operating frequency.
-
Verify pin assignments before connecting the module to your development board.
-
The RA-02 is a radio transceiver, not a Wi-Fi or Bluetooth module.
-
Communication range depends on antenna placement, obstacles, interference, radio settings, and permitted transmission power.
-
Confirm applicable frequency allocation and transmission requirements before deployment.
