LoRa modulation provides dramatically longer range than standard packet radio — over 2 km line-of-sight with default settings and a simple wire antenna, and up to 20 km with tuning and directional antennas.\n\nThis is the 900 MHz LoRa version, which can be software-tuned for either 868 MHz or 915 MHz operation in the license-free ISM bands.\n\nKey Features\n\n\nATmega32u4 @ 8 MHz – 3.3V logic, 32KB flash, 2KB RAM\n\nNative USB – Built-in USB bootloader, serial debugging, and HID device support\n\nRFM95 LoRa Radio (SX1276) – 868/915 MHz LoRa transceiver with SPI interface\n\n+5 to +20 dBm Output – Up to 100 mW selectable in software\n\n2+ km Range – Line-of-sight with default settings; up to 20 km with directional antennas\n\nUltra-Low Sleep Current – ~300 µA in full sleep mode\n\n~120 mA TX at +20 dBm – ~40 mA during active radio listening\n\n20 GPIO Pins – Including 10 analogue inputs and 7 PWM outputs\n\nHardware Serial, I2C & SPI – Full peripheral support\n\nBuilt-in LiPo Charger – 100 mA charging with status indicator LED\n\nBattery Monitoring – Battery voltage routed to an analogue pin via divider\n\n3.3V Regulator – 500 mA peak current output\n\n\nSpecifications\n\n\nDimensions – 51 × 23 × 8 mm (without headers)\n\nWeight – 5.5 g\n\nFrequency – 868 or 915 MHz (ISM band, software-selectable)\n\nMounting – 4 mounting holes\n\n\nAlso Available\n\nFeather 32u4 RFM96 LoRa Radio (433 MHz)\n\nFeather 32u4 RFM69HCW Packet Radio (868/915 MHz) – Shorter range, AES-128 encryption\n\nFeather 32u4 Bluefruit LE – With Bluetooth Low Energy\n\nFeather 32u4 Adalogger – With MicroSD card holder\n\nFeather 32u4 Basic Proto – With prototyping area\n\n\nIdeal For\n\nLong-range wireless sensor networks\nRemote telemetry and environmental monitoring\nLoRa mesh and point-to-point links\nBattery-powered field deployments requiring kilometre-scale range\n\n\nPackage Contents\n\n1× Assembled and tested Feather 32u4 RFM95 LoRa Radio\n1× Header set\n\n\n\nNote: A wire antenna must be soldered on (any solid or stranded core wire is fine). LiPo battery and USB cable are sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":11383,"title":"Default Title","sku":"AF-3078","price":68.19,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
