Product Details

The easyRadio eRA-LoRa (Long Range) RF transceiver module uses Chirped Spread Spectrum (CSS) modulation together with DSP (Digital Signal Processing) to achieve greater range than traditional devices using OOK, FSK or GFSK modulation. In addition, sensitivity and blocking performance are improved giving high interference immunity whilst still offering low power consumption. The module is a complete sub-system that combines a high performance low power RF transceiver, a microcontroller and a voltage regulator.
