Long Range RF Module Wireless Transmitter/Receiver 868MHz LoRa Module SX1276

RF-83SH module is a LoRa spread spectrum module, 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. The communication interface of RF-83SH is SPI, therefore, the MCU driver or a dedicated SPI debug tool is recommended to use.
