Based on the SX1231 transceiver, it provides FSK packet radio with AES-128 encryption, auto-retransmit, and multipoint networking at 868 or 915 MHz (software configurable).\n\nThe breakout includes a 3.3 V regulator and level shifter, so it works with both 3 V and 5 V logic. With +13 to +20 dBm transmit power (up to 100 mW), it can reach approximately 500 m line of sight with a simple wire antenna — up to 5 km with directional antennas and optimised settings.\n\nKey Features\n\n\nSX1231 FSK Packet Radio – RFM69HCW at 868/915 MHz (software configurable) with SPI interface\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\n3.3 V Regulator & Level Shifter – Works with 3 V or 5 V logic and power\n\nArduino Libraries – Ready-to-go with tested support\n\nuFL Antenna Connector – Or solder a simple wire antenna\n\n50–150 mA TX Current – ~30 mA during active listening\n\n\nAlso Consider\n\n\nRFM69HCW Breakout @ 433 MHz – Same radio at 433 MHz\n\n\nIdeal For\n\nWireless sensor networks with Arduino\nRemote control and telemetry\nCampus or farm-wide data links\nEncrypted point-to-point or multipoint communication\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. The frequency is software configurable for 868 or 915 MHz. Some soldering is required to attach headers and a wire antenna (or optional uFL/SMA connector). Check your local regulations for ISM band usage.\n\n\nResources\n\nRFM69HCW Radio Breakout Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11375,"title":"Default Title","sku":"AF-3070","price":19.41,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
