{"title":"Adafruit RFM95W LoRa Radio Transceiver Breakout - 433 MHz","handle":"adafruit-rfm95w-lora-radio-transceiver-breakout-433-mhz","url":"/products/adafruit-rfm95w-lora-radio-transceiver-breakout-433-mhz","description":"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.\n\nLoRa (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.\n\nKey Features\n\n\nSX1276 LoRa Modulation – Long-range spread-spectrum radio, far exceeding standard FSK modules\n\n+5 to +20 dBm Transmit Power – Up to 100 mW output, selectable in software\n\n433 MHz ISM Band – ITU \"Europe\" licence-free ISM frequency\n\n~2 km Range – Line of sight with simple wire antenna; further with directional antennas\n\nSPI Interface – Ready-to-go with Arduino libraries\n\nBuilt-in Voltage Regulator & Level Shifter – Accepts 3–5 V DC power and logic\n\nFlexible Antenna Options – Solder a wire antenna or attach a uFL/SMA connector for an external antenna\n\nLow Power Consumption – ~100 mA peak during +20 dBm transmit, ~30 mA during active listening\n\n\n\nNote: LoRa radios can only communicate with other LoRa radios on the same frequency. This 433 MHz module cannot talk to 868/915 MHz LoRa modules or RFM69-series FSK radios.\n\n\nIdeal For\n\nLong-range sensor networks and remote telemetry\nCampus or town-wide data transmission\nIoT projects requiring extended range over high speed\nAgricultural or environmental monitoring stations\n\n\nPackage Contents\n\n1× Adafruit RFM95W LoRa Radio Transceiver Breakout – 433 MHz\n1× Header strip (soldering required)\n\n\n\nTip: You will need to solder a short piece of wire (any solid or stranded core) to create your antenna. Optionally, attach a uFL or SMA edge-mount connector for an external duck antenna.\n\n\nResources\n\nAdafruit RFM9x LoRa Breakout Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":11440,"title":"Default Title","sku":"AF-3073","price":40.77,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
