Product Description
RF Solutions RFM95W-915S2 LoRa Module is a high-performance wireless transceiver designed for industrial, IoT, and commercial applications requiring long-range and low power communication. It features an outstanding receiver sensitivity of -148 dBm, made possible by the advanced Semtech SX1272 chip utilizing LoRa™ chirp spread spectrum modulation techniques.
The module operates within the 433/868/915MHz ISM frequency bands and supports multiple modulation schemes including LoRa™, FSK, GFSK, MSK, GMSK, and OOK, ensuring compatibility with various protocols such as IEEE 802.15.4 and wM-Bus. The device communicates using a serial SPI interface, facilitating seamless integration with microcontrollers and embedded systems.
Power efficiency is achieved with operation between a supply voltage of 3.3V to 3.7V. The compact form factor of 16mm length and 1.8mm height allows installation in constrained spaces. It can deliver up to 13 dBm RF output power, supporting transmission distances of up to 15 kilometers under ideal line of sight conditions.
The module's robust features include an onboard packet engine supporting up to 256-byte packets with CRC checking, forward error correction with configurable coding rates for enhanced link reliability, and a dynamic RSSI range of 127 dB. Additionally, the device includes an internal temperature sensor and low battery indicator for system diagnostics.
Operating within a temperature range of -20 to +70 degrees Celsius, it is suited for deployment in harsh industrial and environmental conditions. Typical applications include automated meter reading, smart home and building automation, wireless alarm and security systems, industrial monitoring, control setups, and long-range IoT communication networks.
Operates across 433/868/915MHz ISM bands with flexible channel bandwidths of 125kHz, 250kHz, or 500kHz. Supports robust LoRa modulation and standard FSK to maintain coexistence in crowded frequency bands. Provides enhanced interference immunity and has a high dynamic range RSSI sensor.
Extensively used for wireless sensor nodes in smart cities, industrial automation, and agricultural monitoring. RoHS compliant and manufactured in China, guaranteeing quality and regulatory adherence.
