RAK3172-T-9-SM-I 概要
A LoRa module (LoRaWAN transceiver) is a radio-frequency sub-system that implements the physical layer of the LoRaWAN low-power wide-area networking protocol defined by the LoRa Alliance. Within a wireless IoT node hierarchy, a LoRa module sits below the sensor/MCU logic, above the antenna matching network, and is governed by class-A/B/C MAC behavior for uplink/downlink scheduling on sub-GHz ISM frequencies in unlicensed bands.
Key features of the RAK3172-T-9-SM-I include ultra-low-power sleep current suitable for battery-operated nodes, integrated ARM Cortex-M4 application core inside the STM32WLE5, native LoRaWAN 1.0.3 Class A/B/C firmware compatibility, and an SPI/UART/I2C host interface for external sensor integration. The IPEX MHF4 antenna connector simplifies field-replacement antenna selection and supports external high-gain antennas.
The architecture combines STMicroelectronics' STM32WLE5 SoC with an on-board TCXO and RF matching network; this delivers improved frequency stability across temperature and reduced phase noise compared with XTAL-only designs. Internal DC-DC and LDO regulation allow the module to operate directly from 2 V to 3.6 V sources including single-cell Li-SoCl2 primary batteries.
Typical applications include long-range battery-powered IoT sensors, agricultural and environmental telemetry nodes, smart-metering AMR/AMI endpoints, asset tracking, and industrial SCADA wireless extensions. Engineers choose the RAK3172 family for design-reuse compatibility across global LoRaWAN regional bands (8/EU868, 9/US915, AS923) via the trailing band code in the ordering scheme.
When designing with this module, ensure the host PCB reserves a clearance keep-out beneath the IPEX connector, and verify host-MCU UART logic levels are 3.3 V tolerant. Sleep-mode firmware configuration (STM32WL STOP2/STANDBY) is required to meet the uA-class standby current claims needed for multi-year battery life.

主な用途
RAK3172-T-9-SM-I の用途: 6 件s: Battery-Powered IoT Sensor Nodes, Smart Metering and AMR / AMI Endpoints, Agricultural and Environmental Telemetry, Asset Tracking and Logistics Telematics, Industrial Wireless SCADA Extensions, Smart City Lighting and Parking Sensors.
Battery-Powered IoT Sensor Nodes
The RAK3172-T-9-SM-I's 5.22 mA receive current and sub-uA standby figures make it a strong fit for battery-powered IoT sensor nodes on the US915/AU915/AS923 bands. The integrated STM32WLE5CCU6 lets a host MCU delegate RF timing and LoRaWAN MAC state machine to the module, while waking only briefly to push sensor samples via UART. In a remote agricultural soil-moisture monitor, the module transmits one SF11 packet every 15 minutes from a 2.4 Ah primary cell, achieving multi-year battery life. Designers should pair the module with a low-quiescent 3.3 V LDO and add a TVS diode on the antenna feed for surge protection in outdoor installations.

Smart Metering and AMR / AMI Endpoints
Utility metering infrastructure benefits from the RAK3172-T-9-SM-I's 15 km line-of-sight range and Class B/C LoRaWAN support for downlink firmware updates and on-demand reads. The 9-band variant directly maps to US915 FCC Part 15 limits at 902-928 MHz and AU915 compliance rules for meter deployment. Placed behind a meter pulse counter or behind an M-Bus / Modbus host, the module forwards encrypted payloads via AES-128 LoRaWAN session keys; integrated TCXO improves frequency stability versus ambient-temperature XTAL-only modules, reducing base-station gate-way dropouts in cold-weather deployments.
おすすめ
Agricultural and Environmental Telemetry
The RAK3172-T-9-SM-I is well matched to outdoor agricultural telemetry where sensors must operate for years on battery across -40 C to +85 C ambient swings. Its STM32WLE5 sleep current of a few micro-amps preserves battery budget during night-time standby, while the IPEX MHF4 connector permits a high-gain fiberglass antenna for line-of-sight reach across crop fields. Paired with soil-Moisture, temperature, and PAR sensors, a single RAK3172 node can cover 50-100 acres when placed on a 5 m pole. Note: use conformal coating on the module to survive humidity and condensation in tropical deployments.
おすすめ
Asset Tracking and Logistics Telematics
Mobile asset-tracking deployments on US915 / AU915 / AS923 networks favor the RAK3172-T-9-SM-I for its 5.22 mA receive and 87 mA continuous transmit profiles. When combined with a GPS receiver or BLE companion over UART, the module forwards geolocation packets over LoRaWAN at intervals defined by motion-state logic. Slower LoRa spreading factors (SF10-SF12) trade airtime for link margin in container-tracking scenarios where line-of-sight to the gateway is intermittent. Trade-off: high SF11/SF12 packets consume more airtime and battery, so designers should use SF7-SF9 for fixed-route fleet tracking and reserve SF12 only for sparse low-rate updates.
おすすめ
Industrial Wireless SCADA Extensions
For Industrial Wireless SCADA extensions on unlicensed sub-GHz ISM bands, the RAK3172-T-9-SM-I offers transparent UART bridging to LoRaWAN, allowing legacy Modbus RTU devices to be deployed where running cable is impractical. Class C support provides always-on downlink for remote PLC command execution, while the AES-128 LoRaWAN session layer provides security equivalent to many SCADA VPNs. The module's -40 C to +85 C operating range and IPEX connector support external high-gain antennas on factory rooftops, extending the gateway's effective coverage. This is comparable in function to industrial cellular modems but at a fraction of the recurring cost.
おすすめ
Smart City Lighting and Parking Sensors
Municipal smart-city pilots deploy RAK3172-T-9-SM-I nodes for street-light monitoring and parking-occupancy sensing on the 902-928 MHz band. The module's 87 mA peak current and sub-1 mA standby enable solar-powered pole-top installations without trenching power wiring. With SF9 spreading and an SF rate-limited cadence, a single LoRaWAN frame per 5 minutes sustains reliable uplink even through dense urban canyon attenuation. Using the IPEX antenna variant with a low-profile fiberglass whip preserves visual aesthetics on heritage street furniture while delivering 5-6 dBi gain.

設計ノート
Reserve a copper keep-out zone beneath the IPEX MHF4 connector footprint to avoid signal-plane coupling that detunes antenna matching. Place the IPEX connector at the module edge of the host PCB so the antenna can protrude off-board without crossing signal traces. Maintain 50 ohm controlled-impedance routing from the IPEX feed to the on-board RF pad stub if the NI variant is used.
Power the module from a low-quiescent LDO (under 5 uA Iq is ideal) when battery life matters. Decouple the host 3.3 V supply with 10 uF bulk plus 100 nF ceramic directly at the module VIN pads. Voltage transients below 2.0 V during TX bursts will cause the integrated DC-DC to derate RF output power and reduce link margin.
Do not exceed 3.6 V on VIN. Connecting the IPEX antenna port directly to a DC-shorted test fixture will load the matching network and may damage the RF output stage. Always run antenna selection from the -SM-I (IPEX) variant vs -SM-NI (pad) variant at the BOM setup stage - mid-prototype swaps require PCB respins because the host footprint differs at pin 1's antenna signal path.
