FireBeetle Covers-LoRa Radio 433MHz

The DFRobot FireBeetle series is a low - power consumption controller family tailored for IoT development. It focuses on enabling fast and convenient low - power IoT construction. This series includes three types: Boards (main control), Covers (expansion boards), and related Accessories. The FireBeetle LoRa 433MHz wireless transmission module uses a high - performance SX127x LoRa 433MHz chip with a built - in PA (power amplifier) gain and is Arduino - compatible. It supports long - range monitoring, FSK modulation with a max transmission rate of 300Kbps, and LoRaTM with a max rate of 37.5Kbps. In low - power mode, the circuit current is less than 0.2uA. It's ideal for remote home automation detection, health monitoring, and wearable devices. Note: Keep all wireless signal parameters consistent in the same network to avoid communication issues. Specification details: Operating at 3.3V, with a frequency of 433MHz (range: 403MHz - 463MHz), it has multiple modulation types like LoRaTM, FSK, GFSK, and OOK. Output power is ≤20dBm, receiving sensitivity is - 139dBm, and it offers a 1 - Km transmission range. Other features include a built - in aerial for good anti - jamming, 256 - byte FIFO volume, support for CRC frequency - hopping, SPI and GPIO interfaces, and an operating temperature range of - 20℃ to + 70℃. Dimensions are 58 x 29 mm (2.28 x 1.14 inches). Documents include a product wiki and more materials.

Using this FireBeetle LoRa 433MHz cover is easy. First, connect it to your FireBeetle board as per the GPIO and SPI interfaces. Make sure to set the same wireless signal parameters in your network to avoid communication problems. You can use it for long - range monitoring in home automation, health checks, or with wearable devices. For maintenance, keep it in a dry environment within the - 20℃ to + 70℃ temperature range. Don't expose it to water or extreme conditions. If you want to change the transmission mode, refer to the product wiki for detailed steps. And always ensure the power supply is stable at 3.3V.
