Plug it onto the GPIO header and communicate with remote sensor nodes over distances of up to 500 m (line of sight) using the 868 or 915 MHz ISM bands — with built-in AES-128 encryption and auto-retransmit for reliable data delivery.\n\nThe bonnet features an SX1231-based RFM69HCW transceiver with +13 to +20 dBm transmit power (up to 100 mW), a 128×32 OLED display for status messages, and three user-configurable buttons. CircuitPython libraries make it easy to send and receive packetised data, build sensor networks, or create internet gateways using the Pi's built-in networking.\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\n128×32 OLED Display – Built-in screen for status messages and diagnostics\n\n3 User Buttons – For custom interfaces or sending test messages\n\nuFL Antenna Connector – Or solder a simple wire antenna\n\nCircuitPython Libraries – Ready-to-go Python support\n\n50–150 mA TX Current – ~30 mA during active listening\n\nFully Assembled – Plugs directly onto Raspberry Pi GPIO header\n\n\nAlso Consider\n\n\nRFM69HCW Radio Bonnet @ 433 MHz – Same radio at 433 MHz\n\nRadio Bonnet RFM96W LoRa @ 433 MHz – LoRa modulation for longer range\n\n\nIdeal For\n\nWireless sensor networks with Raspberry Pi\nInternet gateways bridging 900 MHz to Wi-Fi/Ethernet\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. An antenna is required (uFL connector or soldered wire) and is not included. Check your local regulations for ISM band usage.\n\n\nResources\n\nAdafruit Radio Bonnets Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7299,"title":"Default Title","sku":"AF-4072","price":38.92,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
