Uses the license-free ISM bands +13 to +20 dBm up to 100 mW
Works with the Feather ESP8266, Feather 32u4, WICED Feather, Teensy 3 Feather and Feather M0 series
Range of approx. 350 meters, depending on obstructions, frequency, antenna and power output
Add short-hop wireless to your Feather with these RadioFruit Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x's). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device.
This RFM69 @ 900 MHz version can be used for 868 MHz or 915 MHz (the radios use software configured frequency. These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit. They can go at least 500 meters line of sight using simple wire antennas, probably up to 5Km with directional antennas and settings tweakings. You can create multipoint networks with individual node addresses. Some wiring is required to configure the FeatherWing for the chipset you plan to use. This radio can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz. Each radio 'Wing comes with some header. Some soldering is required to attach the header.
