Description of product: DFRobot FireBeetle Covers-LoRa 868 MHz
The FireBeetle module equipped with LoRa SX1276 868MHz module with built-in PA (Power Amplifier), controlled through theSPIinterface. The maximum data transfer rate is300 Kbps. It also supportsLoRaTM,it provides maximum transfer rate equal to37.5 Kbps. The module is powered with the voltageof 3.3 V.
Designed for IoT projects (Internet of Things). The current consumption in sleep mode is0,2 uA. It can be used in projects for remote control of devices in home automation, health monitoring, intelligent clothing, etc.
The pins of the DFRobot FireBeetle 868 MHz module
The module communicates via SPI (MISO, MOSI, SCK, CS, RESET) interface. You must connect these pins to the MISO, MOSI, CCS on FireBeetle board and CS, and the Reset to the D2, D3, D4, D5 connector with connecting wires. More information can be found inthe user manualprepared by the manufacturer.
