Adafruit LoRa Radio FeatherWing - RFM95W 433 MHz PRODUCT ID: 3232
Description
Add short-hop wireless to your Feather with these Radio 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 \\RXUPRELOHGHYLFH 7KHVHUDGLRPRGXOHVFRPHLQ¬IRXUYDULDQWV¬ WZRPRGXODWLRQW\\SHVDQGWZRIUHTXHQFLHV 7KH RFM69's are easiest to work with, and are well known and understood.
