DFRobot TEL0125 868MHz FireBeetle LoRa Module

DFRobot TEL0125 868MHz FireBeetle LoRa Module is a low-power consumption microcontroller especially designed for the Internet of Things (IoT). The TEL0125 FireBeetle covers-LoRa radio 868MHz mainly communicates via SPI interface and focuses on fast and convenient low-power building. This LoRa radio is a wireless transmission module that adopts a high-performance SX1276 LoRa 868MHz chip with built-in Power Amplifier (PA) gain and is compatible with Arduino. The TEL0125 module provides a maximum transmission rate and can reach up to 300Kbps. This FireBeetle LoRa module supports long-range monitoring and FSK modulation. The TEL0125 module is widely used in remote home automation detection, health monitoring, and wearable device.
