This breakout is built around the EBYTE 915M30S module, giving you a 1W (30dBm) LoRa transceiver for long-range, low-data-rate wireless projects. LoRa is well suited to links over long distances, low-power sleep operation and data rates around ~500bps.
The board is designed to connect to any platform with SPI and 6 available GPIO. For antennas, it includes a sturdy edge-mount RP-SMA connector for larger 915MHz LoRa antennas, plus an on-board U.FL connector if you need to route an antenna outside a metal enclosure.
SparkFun has achieved 12 miles line-of-sight with this module in testing, though real-world range will vary with antennas, terrain and installation. Example sketches are provided for initial SX1276 setup, and the Arduino RadioLib library supports advanced configuration and protocols including AX.25, Hellschreiber, Morse, RTTY and SSTV.
This is a SparkX experimental product: it is tested, but live technical support is not available for SparkX products.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- 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.
- 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.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
- 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.
- u.FL
- u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
