Long-Range 433MHz LoRa Radio for Reliable Low-Power Data Links
The Adafruit RFM96W LoRa Radio Transceiver Breakout - 433 MHz is a compact long-range wireless module for projects that need to send data farther than typical 2.4GHz radios. Built around the SX1276 LoRa transceiver, this breakout is ideal for sensor nodes, telemetry links, remote monitoring, and low-bandwidth control systems where range matters more than high-speed data transfer.
Unlike WiFi or Bluetooth, LoRa is designed for efficient long-distance packet communication. That makes this breakout a strong choice for environmental monitoring, outdoor devices, campus-scale experiments, agricultural projects, and custom point-to-point wireless systems.
Important: This breakout is a 433 MHz LoRa radio. It can only communicate with other radios using the same LoRa family and matching frequency. It is not compatible with standard WiFi, Bluetooth, or mismatched packet radio modules.
Why you'll love it
- LoRa long-range performance for low-bandwidth wireless communication
- 433 MHz operation for projects using this frequency band
- SX1276-based design with proven SPI interface support
- 3V or 5V friendly thanks to onboard regulator and level shifting
- Software-selectable transmit power from +5 dBm to +20 dBm
- Flexible antenna options with simple wire antenna support plus pads for uFL or SMA connectors
What you can build
This breakout is great for remote sensor nodes, farm monitoring systems, long-range Arduino data links, environmental logging, wireless alert systems, telemetry projects, and custom low-power radio networks where simple packet transfer is more important than internet connectivity.
Starter bundles
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi Pico, along with header pins, jumper wires, and a small antenna setup for fast prototyping.
Recommended add-ons
For better range and cleaner installation, consider adding an SMA connector, uFL connector, compatible antenna, or a weatherproof enclosure for outdoor builds.
Technical specifications
| Product | Adafruit RFM96W LoRa Radio Transceiver Breakout - 433 MHz |
|---|---|

Pinout & power notes
The breakout uses an SPI interface, so it connects easily to microcontrollers that support SPI communication. Since the board already includes level shifting and a 3.3V regulator, it is easier to use with both 3.3V and 5V systems than a bare radio module.
You will need to add an antenna before use. A short wire antenna is the simplest option, while uFL or SMA connectors can be added for external antennas and more flexible installations.

Frequently Asked Questions
Is this WiFi or Bluetooth?
No. This is a LoRa packet radio made for long-range, low-bandwidth wireless communication.
Can it talk to any 433MHz radio?
No. It must match the same radio family and frequency. A 433MHz LoRa module should be paired with another compatible 433MHz LoRa module.
Does it need an antenna?
Yes. You need to attach a wire antenna or add an optional uFL or SMA connector with an external antenna.
Can I use it with Arduino?
Yes. It works well with Arduino and other microcontrollers through SPI, and the board is designed to handle both 3V and 5V logic levels.
Is this good for LoRaWAN?
This breakout is primarily a LoRa transceiver module. Whether you use it in a LoRaWAN setup depends on your overall hardware and software stack.
