Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003eLoRa module RFM95PW-868S2\u003c\/h1\u003e\n\n\u003cp\u003eThe RFM95PW-868S2 is a high-performance LoRa transceiver module operating in the 868 MHz ISM band, designed for long-range wireless communication with ultra-low power consumption. IoT developers, embedded systems engineers, and wireless network architects use this module to build scalable mesh networks, remote sensor deployments, and smart city applications requiring kilometers of range with minimal battery drain. This module solves the critical challenge of achieving extended wireless coverage in unlicensed frequency bands while maintaining sub-milliwatt sleep currents, making it ideal for battery-powered IoT devices that must operate for months or years without maintenance.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\n\u003cp\u003eThe RFM95PW-868S2 utilizes Semtech's SX1276 LoRa modulation technology, which spreads data over a wide bandwidth to achieve exceptional sensitivity down to -148 dBm. This advanced spread spectrum technique allows the module to maintain reliable communication at distances exceeding 10 kilometers in open space and several kilometers through urban obstacles, while operating at transmit power levels as low as 2 dBm to 20 dBm. The module integrates a complete RF front-end with antenna matching network, eliminating the need for external RF components and simplifying PCB design for rapid prototyping and production deployment.\u003c\/p\u003e\n\n\u003cp\u003eWhat distinguishes the RFM95PW-868S2 is its exceptional power efficiency combined with flexible configuration options. The module supports multiple spreading factors (SF7 through SF12) allowing developers to trade off data rate against range and power consumption based on application requirements. With sleep current below 1 microampere and wake-up times under 10 milliseconds, this module enables battery-powered devices to achieve multi-year operational lifespans. The integrated SPI interface operates at up to 10 MHz, providing fast configuration and data transfer while the DIO pins offer flexible interrupt-driven operation for event-based processing in resource-constrained environments.\u003c\/p\u003e\n\n\u003ch2\u003eKey

Use\u003c\/h2\u003e\n\n\u003cp\u003eTo implement the RFM95PW-868S2 in your project, connect the module to your microcontroller via SPI bus (MOSI, MISO, CLK, CS pins) and configure the supply voltage to 3.3V with adequate decoupling capacitors (100nF ceramic and 10uF electrolytic) placed close to the module's power pins. Initialize the module through SPI by writing configuration registers to set the desired frequency (868 MHz), spreading factor (SF7-SF12 based on range requirements), bandwidth (125 kHz recommended for most applications), and transmit power (2-20 dBm). Configure the DIO0 pin as an interrupt input to your microcontroller to detect transmission complete and reception complete events, enabling efficient event-driven firmware architecture that minimizes power consumption.\u003c\/p\u003e\n\n\u003cp\u003eFor reliable operation, implement proper antenna matching by maintaining the PCB antenna clear of ground planes in the immediate vicinity (minimum 5mm clearance recommended) and avoid routing high-speed digital signals near the antenna trace. Use SPI clock speeds up to 10 MHz for efficient register access, and implement software timeout mechanisms when waiting for transmission completion since the module may take several hundred milliseconds to transmit at maximum spreading factors. For applications requiring mesh networking, implement packet routing firmware that allows received packets on DIO0 to be relayed through the module's transmitter, enabling multi-hop topologies that extend network coverage beyond single-hop limitations.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum range achievable with the RFM95PW-868S2?\u003c\/summary\u003e\n\u003cp\u003eMaximum range depends on spreading factor, antenna configuration, and environmental obstacles. In open space with SF12 (maximum spreading factor), the module achieves 10-15 kilometers. In urban environments with buildings and obstacles, expect 2-5 kilometers depending on construction materials. Range can be extended through mesh networking where multiple modules relay packets across greater distances. Higher spreading factors increase range but reduce data rate and increase transmission time, so select SF based on your specific latency and throughput requirements.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow long can a battery-powered device operate with the RFM95PW-868S2?\u003c\/summary\u003e\n\u003cp\u003eBattery life depends on sleep current, transmission frequency, and spreading factor used. With the module in sleep mode consuming less than 1 microampere and transmitting once per hour at SF7, a 2000 mAh battery can provide 2-3 years of operation. If transmitting every 10 minutes at SF12, battery life reduces to 3-6 months. Use the module's sleep mode aggressively between transmissions, configure wake-up through external interrupt or timer, and select the lowest spreading factor that maintains reliable communication to maximize battery life in your specific application.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan the RFM95PW-868S2 operate in frequency bands other than 868 MHz?\u003c\/summary\u003e\n\u003cp\u003eThe RFM95PW-868S2 is specifically designed and certified for the 868 MHz ISM band used in Europe and other regions. It cannot be reconfigured to operate at different frequencies like 433 MHz or 915 MHz. If you require operation at different frequencies, Semtech offers variant modules such as RFM95PW-915S2 for 915 MHz (North America) or RFM95PW-433S2 for 433 MHz. Attempting to operate outside the certified frequency band may violate local radio regulations and cause interference with licensed services.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between LoRa and LoRaWAN?\u003c\/summary\u003e\n\u003cp\u003eLoRa is the modulation technique and physical layer used by the RFM95PW-868S2 for long-range wireless communication. LoRaWAN is a network protocol built on top of LoRa that defines how devices join networks, authenticate, and manage encryption. The RFM95PW-868S2 module handles only the LoRa physical layer; you must implement LoRaWAN protocol stack in your microcontroller firmware if you need LoRaWAN compatibility. Many IoT applications use raw LoRa without LoRaWAN for simpler point-to-point or mesh networks where centralized network management is not required.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
