Adafruit Radio FeatherWing - RFM69HCW 433MHz - RadioFruit

Add short-hop wireless to your Feather with the Adafruit Radio FeatherWing featuring the RFM69HCW 433MHz RadioFruit module. This add-on board enables packetized FSK/GFSK/MSK/GMSK/OOK radio communication at 433 MHz on the license-free ISM band, suitable for Europe ITU 1 and amateur use depending on local regulations.

The RFM69HCW module is a +20dBm FSK packet radio with built-in encryption and auto-retransmit. It offers a range of approximately 350 meters line-of-sight with simple wire antennas, and up to 5 kilometers with directional antennas and proper tuning. It allows multipoint networks with unique node addresses.
