RF-LORA-868-SO - 868MHz LoRa Transceiver Module, 16km | RF Solutions
MPN： RF-LORA-868-SO ✓ 啟用中RF-LORA-868-SO 概覽
A LoRa module is a sub-GHz radio transceiver sub-system that implements LoRa (Long Range) chirp spread spectrum modulation, a technology within the LPWAN (low-power wide-area network) family of radio standards. Unlike short-range protocols such as Bluetooth or Wi-Fi, LoRa trades data rate for link budget, enabling kilometer-scale links at milliamp-level currents - the reason it dominates battery-powered IoT telemetry.
Key features of the RF-LORA-868-SO include the Semtech SX1272 chipset with ultra-long-range spread-spectrum communication and high interference immunity at minimal current consumption, receive-mode current of approximately 10 mA, a wide 2.2 V to 3.7 V supply range suitable for single lithium cell operation, and a 16 km maximum range. The module is a plug-and-play design intended to minimize RF design effort for OEM boards.
Technically, the SX1272-based architecture supports multiple modulation schemes including LoRa, FSK, GFSK, GMSK, MSK and OOK, giving designers flexibility between raw packet radios and long-range LoRa links. The castellated SMT footprint permits reflow soldering directly onto the host PCB, with the antenna connected via an external feed point (antenna not included).
Typical applications include smart metering, agricultural and environmental sensor networks, asset tracking, and general ISM-band (< 1 GHz) telemetry across Europe where the 868 MHz band is licensed-exempt.
Design consideration: keep the transmit duty cycle within the 868 MHz band regulations, and provide a proper 50-ohm ground-referenced antenna feed - poor antenna matching is the most common cause of underperforming LoRa links.
This page adds value beyond the datasheet by synthesizing distributor pricing (as of 2026-10-19), drop-in alternatives from the same family, and practical RF layout guidance in one reference.

典型應用
RF-LORA-868-SO 適用於 6 應用s: Smart Metering, Agricultural Sensor Networks, Asset Tracking and Telemetry, Industrial IoT and SCADA Telemetry, Smart City and Street Lighting Control, Environmental and Smart Home Monitoring.
Smart Metering
The RF-LORA-868-SO fits smart utility metering because the 868 MHz EU ISM band is license-free for telemetry and the -130 dBm sensitivity penetrates basements and meter cabinets that defeat 2.4 GHz radios. Drawing only 10 mA in receive and 71.5 mA at 20 dBm transmit on a 2.2-3.7 V rail, the module supports battery-backed meters targeting 10+ year service. The SPI interface connects directly to the metering MCU, which handles protocol framing. Placed behind a 50-ohm whip or PCB antenna, the 16 km link budget covers neighborhood-scale collections without repeaters, though duty-cycle limits on EU868 must be respected in dense networks.

Agricultural Sensor Networks
The RF-LORA-868-SO is well suited to agricultural telemetry - soil moisture, weather stations, irrigation valves - where nodes are spread over hundreds of hectares beyond Wi-Fi or cellular coverage. The Semtech SX1272 chirp spread spectrum tolerates the fading and interference of crop canopies, and the -130 dBm sensitivity with 16 km line-of-sight range lets a single gateway cover an entire farm. Nodes run on small lithium cells thanks to the 2.2-3.7 V input and milliamp receive current. Design consideration: keep gateways elevated for line-of-sight and schedule uplinks to respect the 868 MHz duty-cycle regulations when polling many nodes.
推薦
Asset Tracking and Telemetry
For logistics and asset tracking, the RF-LORA-868-SO provides kilometer-scale check-ins at very low energy cost: a 20 dBm burst at 71.5 mA for tens of milliseconds per report keeps average consumption in the microamp range on duty-cycled hardware. LoRa geolocation of trackers without GPS is possible through gateway signal fingerprinting, extending battery life further. The castellated SMT package reflows directly onto the tracker PCB next to the host MCU over SPI, and the external antenna feed allows the antenna to be placed clear of the metal enclosure. Note the 0 C to +55 C operating range when tracking in cold-chain or unheated freight environments.

Industrial IoT and SCADA Telemetry
In factories and utility substations, the RF-LORA-868-SO bridges hard-to-wire sensors - tank levels, pressure, valve position - back to SCADA without cabling through concrete or hazardous areas. The SX1272 high interference immunity resists the electrically noisy plant floor, and the 20 dBm output with -130 dBm sensitivity gives margin through steel-clad buildings where lower-power radios fail. The SPI interface and plug-and-play module design shorten certification effort versus discrete RF. Place the module with a solid ground plane and a remote antenna feed to escape shielded cabinets; plan polling intervals around EU868 duty-cycle limits to keep network capacity for critical alarms.

Smart City and Street Lighting Control
Street lighting and city infrastructure control benefit from the RF-LORA-868-SO long reach: one 868 MHz gateway with the module's 16 km class link budget can command hundreds of lamp controllers across a district. The module's 10 mA receive current and sleep capability suit always-listening nodes powered from the lamp driver's standby supply, while the SPI link keeps the lighting MCU fully in charge of switching logic and schedules. LoRa's interference immunity handles the dense RF noise of urban rooftops. Use the castellated footprint under the luminaire's polycarbonate canopy with a vertical antenna feed to maximize urban propagation and verify message acknowledgment latency in dense deployments.
推薦
Environmental and Smart Home Monitoring
For environmental monitoring - air quality, flood detection, weather nodes - and smart home hubs, the RF-LORA-868-SO offers a private long-range radio that does not depend on Wi-Fi infrastructure or cellular coverage. The 2.2-3.7 V input runs directly from coin cells with boost regulation or primary lithium cells, and the -130 dBm sensitivity keeps links alive through walls and garden boundaries where 2.4 GHz links drop. The SX1272 also supports FSK/GFSK modes for short-range high-rate signaling to nearby sensors. Keep the antenna clear of metal enclosures and respect the 0 C to +55 C temperature rating for outdoor-only-rated placements.

主要差異化特點
- EU868 band-optimized LoRa in a plug-and-play SMT module (對比RF-LORA-868-PO)
- -130 dBm sensitivity for maximum link budget (對比RF-LORA-433-SO)
- Identical footprint across regional variants (對比RF-LORA-915-SO)
設計說明
Keep the RF feed from the module antenna pad to the antenna connector as short as possible, over an unbroken 50-ohm ground reference. Do not route SPI, power, or fast digital traces under or parallel to the antenna feed. The SX1272-based front end is sensitive; a poorly matched feed is the most common cause of a LoRa link underperforming its -130 dBm sensitivity figure.
Supply the module from a clean 2.2-3.7 V rail. Transmit bursts reach 71.5 mA; use at least a 10 uF bulk capacitor plus a 100 nF ceramic close to the supply pin. A 3.3 V LDO with adequate transient response is preferred over sharing a noisy digital rail. Brown-out during TX bursts is a common failure mode in battery nodes.
The module is specified from 0 C to +55 C - do not use it in unheated outdoor enclosures in cold climates without verifying behavior. Also respect EU868 duty-cycle regulations: the 20 dBm output cannot be transmitted continuously. Finally, the antenna is not included; an untuned or missing antenna can damage the SX1272 PA during transmit.
Provide a ground plane beneath the module and connect all ground castellations with multiple vias. The castellated edge allows reflow soldering, but for prototyping hand placement, ensure paste on the RF ground pads to avoid intermittent ground returns that degrade sensitivity.
