DFRobot FireBeetle IOT series (https://www.dfrobot.com/category-247.html) are low power consumption controllers designed for Internet of Things (IoT) development. The FireBeetle
series (https://www.dfrobot.com/category-247.html) are aiming straight at the point fast and convenient low-power IoT building. There are three categories of FireBeetle series, containing
Boards (main control), Covers (expansion boards) and related Accessories.
FireBeetle LoRa 433MHz wireless transmission module adopts a high-performance chip SX127x LoRa 433MHz and with built-in PA (power amplifier) gain, compatible with Aruino. It
supports long-range monitor, FSK modulation and the maximum transmission rate is 300K[null bps]. It also supports LoRaTM, the maximum transmission rate is 37.5Kbps. The circuit
current is even lower than 0.2uA in the low power mode. It can be widely used in remote home automation detection, health monitoring and wearable device and so on.
NOTE: All parameters related to wireless signals in the same network should maintain consistency to avoid communication problems.
