These add-ons for any board will let you integrate packetized radio (with the RFM69 radio) or 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.
These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood. The radios are exciting, longer-range and more powerful but also more expensive.
This is the 9x @ 433 MHz radio version - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings
Currently tested to work with the ESP8266, Teensy 3 Feather, 32u4 and M0 series, some wiring is required to configure the for the chipset you plan to use.
All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, 433 MHz can only talk to 433, etc.
Each radio 'Wing comes with some header. Some soldering is required to attach the header. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Optionally you can pick up a uFL or SMA edge-mount connector and attach an external duck. .
