DFRobot FireBeetle series are low power consumption micro-controllers specially designed for Internet of Things (IoT), and mainly focusing on fast and convenient low-power building.

FireBeetle LoRa 868MHz wireless transmission module adopts a high-performance SX1276 LoRa 868MHz chip and with built-in PA (power amplifier) gain, compatible with Arduino. It supports long-range monitor and FSK modulation. The maximum transmission rate of the module can reach up to 300Kbps. The module also supports LoRaTM and can provide a maximum transmission of 37.5Kbps. The circuit current is even lower than 0.2uA in the sleep mode. It can be widely used in remote home automation detection, health monitoring, wearable device and so on.
