{"title":"LoRa Radio Module - 433MHz","handle":"lora-radio-module-433mhz","url":"/products/lora-radio-module-433mhz","description":"A long-range, low-data-rate radio modem pair based on the Semtech SX1276 LoRa transceiver. Operating on the 433 MHz ISM band, these modules deliver robust wireless links with excellent sensitivity and low power consumption — ideal for remote sensing and IoT applications.\n\nThe modules support two operating modes: Standard mode for transparent serial data passthrough, and Star network mode where one module acts as a central node communicating bidirectionally with multiple node modules. Configuration is done via TTL serial commands.\n\nKey Features\n\n\nLoRa Spread Spectrum – Long-range communication on the 433 MHz ISM band\n\n−148 dBm Receive Sensitivity – Excellent range in noisy environments\n\n≤20 dBm Output Power – Up to 100 mW transmit power\n\nUltra-Low Sleep Current – ≤3.9 µA for battery-powered deployments\n\nDual Operating Modes – Transparent serial modem or star network topology\n\nSerial Wake-Up & Wireless Wake-Up – Flexible power management\n\nWide Voltage Range – 2.1–3.6 V (battery) or 4.5–5.5 V\n\nTTL Serial Interface – 1,200–57,600 bps (default 9,600)\n\nOperating Temperature – −40°C to +80°C\n\nDimensions – 34.2 × 18.4 mm\n\n\nIdeal For\n\nLong-range wireless sensor networks\nIoT and remote monitoring projects\nPoint-to-point serial data links\nStar network topologies with a central hub\n\n\n\nNote: These modules use a proprietary star network protocol and are not compatible with LoRaWAN. A USB-to-TTL converter is recommended for configuring module parameters.\n\n\nPackage Contents\n\n2× LoRa Radio Module – 433 MHz\n2× 433 MHz Antenna (SMA-Male connector)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8551,"title":"Default Title","sku":"DF-TEL0116","price":77.79,"on_sale":false,"in_stock":true,"available_quantity":25,"option1":"Default Title"}]}
