The Adafruit RFM95W LoRa Radio Transceiver Breakout lets you send data over very long distances using the 433 MHz licence-free ISM band. Based on the SX1276 LoRa chipset, this breakout achieves ranges of approximately 2 km line of sight with a simple wire antenna — or up to 20 km with directional antennas and optimised settings.
LoRa (Long Range) modulation trades raw data speed for dramatically extended range compared to WiFi or Bluetooth. These packet radios require no pairing or association — simply send data and any matching receiver will pick it up. The module handles packetisation, error correction, and auto-retransmit automatically.
Key Features
- SX1276 LoRa Modulation – Long-range spread-spectrum radio, far exceeding standard FSK modules
- +5 to +20 dBm Transmit Power – Up to 100 mW output, selectable in software
- 433 MHz ISM Band – ITU "Europe" licence-free ISM frequency
- ~2 km Range – Line of sight with simple wire antenna; further with directional antennas
- SPI Interface – Ready-to-go with Arduino libraries
- Built-in Voltage Regulator & Level Shifter – Accepts 3–5 V DC power and logic
- Flexible Antenna Options – Solder a wire antenna or attach a uFL/SMA connector for an external antenna
- Low Power Consumption – ~100 mA peak during +20 dBm transmit, ~30 mA during active listening
Ideal For
- Long-range sensor networks and remote telemetry
- Campus or town-wide data transmission
- IoT projects requiring extended range over high speed
- Agricultural or environmental monitoring stations

Resources
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.
- 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.
- 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.
