RF-82SH module is a LoRa spread spectrum module which is capable of achieving significantly longer range than existing systems based on FSK or OOK modulation, with operating frequency of 868 MHz ~ 893 MHz & 900 MHz ~ 931 MHz, based on the Semtech SX1276. It is a wireless SPI transceiver module with 3.3 V TTL level output. RF-star LoRa module features with ultra-long range spread spectrum communication, concentrated power density, high interference immunity ability, confidentiality, and significantly lower current consumption, which can provide significant advances in selectivity and blocking performance, further improving communication reliability. The communication interface of RF-82SH is SPI, therefore, the MCU driver or a dedicated SPI debug tool is recommended to use.
