DFRobot FireBeetle series are low power consumption controllers designed for Internet of Things (IoT) development. The FireBeetle series 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.

Jargon buster
Plain-language definitions for the technical terms used above.
- FIFO
- FIFO stands for “first in, first out” and is a small memory buffer inside the sensor that stores recent readings in order. This matters because it can help capture motion data without the microcontroller needing to read the sensor every single instant.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LoRa
- LoRa is a long-range, low-power radio technology often used for telemetry and remote sensors. It matters here because the connector and pinout are compatible with some LoRa telemetry products, even though this module uses Bluetooth instead.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
