{"title":"Adafruit Radio FeatherWing - RFM69HCW 900MHz","handle":"adafruit-radio-featherwing-rfm69hcw-900mhz","url":"/products/adafruit-radio-featherwing-rfm69hcw-900mhz","description":"The Adafruit Radio FeatherWing RFM69HCW @ 900 MHz adds short-to-medium range packet radio to any Feather board. Based on the SX1231 transceiver, this FeatherWing provides FSK packet radio with built-in AES-128 encryption, auto-retransmit, and multipoint networking at 868/915 MHz (software configurable).\n\nWith +13 to +20 dBm transmit power (up to 100 mW), the RFM69HCW can reach approximately 500 m line of sight with a simple wire antenna, and potentially up to 5 km with directional antennas and optimised settings. Pair it with a Wi-Fi, cellular, or Bluetooth Feather to bridge 900 MHz radio to the internet.\n\nKey Features\n\n\nSX1231 FSK Packet Radio – FSK/GFSK/MSK/GMSK/OOK modulation at 868/915 MHz\n\n+13 to +20 dBm Transmit Power – Up to 100 mW, selectable in software\n\n~500 m Range – Line of sight with wire antenna; up to 5 km with directional antennas\n\nAES-128 Encryption – Built-in hardware encryption engine\n\nAuto-Retransmit – Automatic packet retransmission for reliability\n\nMultipoint Networking – Individual node addresses for creating networks\n\nSPI Interface – Connects to Feather via SPI bus\n\n50–150 mA TX Current – 50 mA at +13 dBm, 150 mA at +20 dBm\n\nArduino Libraries – Ready-to-go with tested support\n\n\nAlso Consider\n\n\nRadio FeatherWing RFM69 @ 433 MHz – Same radio at 433 MHz for European ISM band\n\n\nIdeal For\n\nWireless sensor networks\nRemote control and telemetry\nBridging 900 MHz radio to internet via Wi-Fi/cellular Feathers\nEncrypted point-to-point or multipoint data links\n\n\n\nNote: Radios can only communicate with other radios of the same type and frequency — RFM69 900 MHz talks only to RFM69 900 MHz. Some soldering is required to attach headers and a wire antenna (or optional uFL/SMA connector). The frequency is software configurable for 868 or 915 MHz — check your local regulations for ISM band usage.\n\n\nResources\n\nAdafruit Radio FeatherWing Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12077,"title":"Default Title","sku":"AF-3229","price":20.11,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
