Add long-range LoRa radio to any Feather board with the Adafruit LoRa Radio FeatherWing. Built around the SX127x LoRa module, this add-on provides kilometre-range packet radio communication at 433 MHz — perfect for sensor networks, remote monitoring, and bridging to the Internet via a WiFi or cellular Feather.
Unlike WiFi or Bluetooth, LoRa uses simple packet-based communication with no pairing or association needed. With default settings, expect over 2 km line-of-sight range using a simple wire antenna, or up to 20 km with directional antennas and optimised settings.
Key Features
- SX127x LoRa Module – 433 MHz with SPI interface, software-tuneable frequency
- +5 to +20 dBm Output – Up to 100 mW transmit power, selectable in software
- ~2 km Range – Line-of-sight with wire antenna; up to 20 km with directional antennas
- Low Power – ~300 µA full sleep, ~120 mA peak transmit at +20 dBm, ~40 mA active listening
- Flexible Antenna Options – Solder pad for wire antenna, or add a uFL/SMA edge-mount connector
- Arduino Libraries – Ready-to-use packet radio libraries
- FeatherWing Form Factor – Stacks onto any Feather board
Ideal For
- Long-range sensor networks and remote data collection
- LoRa-to-Internet gateways via WiFi or cellular Feathers
- Campus or farm-wide wireless communication
- Battery-powered remote monitoring stations
Package Contents
- 1× Adafruit LoRa Radio FeatherWing (RFM95W @ 433 MHz)

Jargon buster
Plain-language definitions for the technical terms used above.
- FeatherWing
- A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
- 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.
