WSSFM10R1AT - Sigfox RCZ1 868MHz AT-Command RF Module | WISOL/SeongJi
MPN: WSSFM10R1AT ✓ Hoạt độngWSSFM10R1AT Tóm tắt
A Sigfox module is a pre-certified radio module that implements the proprietary Sigfox Low-Power Wide-Area Network (LPWAN) protocol stack, which sits above the physical sub-1 GHz layer (typically 868 MHz in Europe) and below the application firmware. Within the broader taxonomy, Sigfox belongs to LPWAN -> Low-Power Wide-Area Networking -> Wireless Connectivity -> RF & Wireless modules -> Semiconductor assemblies. By embedding the full Sigfox protocol stack and offering AT-command control, the WSSFM10R1AT lets product firmware treat the radio as a black-box modem rather than re-implementing the physical and MAC layers on a bare transceiver.
Key features of the WSSFM10R1AT include: Sigfox RCZ1 zone compliance (ETSI EN 300 220), an integrated 31-pin SMD form factor, AT-command interface for UART-driven control, and an ultra-low-power sleep mode suited to coin-cell and battery-operated IoT endpoints. The module operates from a single 3.3 V supply typical of low-power IoT sensor nodes, and integrates the matching network, SAW filter, and crystal reference, simplifying host PCB design. Pin 1 marking and 31-pin SMD pad pattern enable surface-mount assembly on standard reflow profiles.
The architecture combines a sub-1 GHz RF transceiver core with an on-board microcontroller running the Sigfox protocol stack. The host MCU communicates with the module over UART using AT commands, transparently handling Sigfox frame formation, sequence-number generation, and ETSI duty-cycle compliance. This offloads a significant firmware burden from the host, allowing the application processor to focus on sensing, local processing, and power management rather than radio protocol details.
Typical applications include wireless battery field monitoring, smart parking sensors, asset tracking, environmental monitoring (temperature, humidity, air quality), smart agriculture soil/livestock sensors, and industrial IoT endpoints requiring multi-year battery operation. The RCZ1 zone targets Europe, the Middle East, and parts of Africa where Sigfox 868 MHz infrastructure is deployed.
When designing with this module, observe the antenna placement guidelines from the manufacturer: keep the antenna radiating element clear of ground planes and battery metals, and route the host UART lines away from noisy switching power traces to avoid coupling into the receiver. Pay attention to host-side flow-control handshaking during long Sigfox frame transmissions.

Ứng dụng tiêu biểu
WSSFM10R1AT phù hợp cho 6 Áp dụngs: Wireless Battery Field Monitoring, Smart Parking Sensors, Asset Tracking and Logistics, Environmental Monitoring, Smart Agriculture Soil and Livestock Sensors, Industrial IoT Endpoints.
Wireless Battery Field Monitoring
The WSSFM10R1AT is well suited to wireless battery-field monitoring where low-duty-cycle uplink telemetry must travel kilometers from a remote sensor. With Sigfox RCZ1 868 MHz coverage, a 13 x 15 x 2.21 mm SMD footprint, and an integrated AT-command interface that offloads the Sigfox stack from the host MCU, the module fits inside sealed battery housings. Battery-life modeling based on Sigfox 140-uplink-per-day limits gives multi-year operation on lithium primary cells. Place the external antenna at the housing top and route UART traces away from the battery tab to minimize coupling.

Smart Parking Sensors
The WSSFM10R1AT enables compact wireless parking sensors that report occupancy over the Sigfox 868 MHz network. The AT-command UART interface lets a small magnetic or radar-sensor host MCU push Sigfox frames without implementing the radio stack, freeing Flash and CPU for sensing. The sub-1 GHz 868 MHz band penetrates asphalt and concrete well, and the 31-pin SMD form factor fits within a road-surface puck. Antenna tuning must avoid metallic rebar proximity in parking decks.
Được đề xuất
Asset Tracking and Logistics
The WSSFM10R1AT supports indoor/outdoor asset tracking by transmitting Sigfox IDs from pallets, containers, and high-value assets. The 868 MHz signal propagates through warehouse racking and offers building penetration suitable for logistics tracking. The module's small SMD footprint enables integration inside reusable trackers. Multi-year battery life on primary cells keeps total cost of ownership low; recommend including an accelerometer wake source to maximize uplink signal to keep Sigfox frames energy-efficient.
Được đề xuất
Environmental Monitoring
The WSSFM10R1AT is widely used in environmental monitoring stations that measure temperature, humidity, CO2, or particulate matter and report over the Sigfox 868 MHz network. Sigfox's low duty cycle and the module's sub-1 GHz penetration enable reliable uplink from indoor air-quality sensors in offices and HVAC ducts. The AT-command interface keeps sensor-firmware complexity low, allowing sensor partners to focus on measurement accuracy rather than radio protocol details.

Smart Agriculture Soil and Livestock Sensors
The WSSFM10R1AT fits outdoor agricultural deployments where 868 MHz signals propagate well across open fields and livestock ranges. Soil-moisture probes, weather stations, and livestock ear-tags benefit from the module's SMD form factor and multi-year battery life on primary cells. The AT-command interface is easy to integrate with low-cost agricultural MCUs. Antenna placement above the soil canopy or above the animal's ear improves link margin in real deployments.
Được đề xuất
Industrial IoT Endpoints
The WSSFM10R1AT integrates into industrial IoT endpoints that report machine status, vibration, or temperature from equipment cabinets. Sigfox's public 0G network eliminates the need to deploy a private gateway, reducing CapEx. The 868 MHz band penetrates industrial enclosures and concrete walls. The module's AT-command interface is straightforward to integrate with industrial PLC and edge-controller UART ports, simplifying predictive-maintenance telemetry deployment.

Ghi chú thiết kế
The WSSFM10R1AT's external antenna feed is the single most layout-sensitive element on the host PCB. Keep the 50-ohm RF trace short and reference-grounded, route it on the top layer with a continuous ground plane beneath, and avoid routing digital signals across it. Place the U.FL connector or PCB antenna radiating element at least 5 mm from any battery tab, metal shield, or ground cutout that could shift the antenna resonance below 868 MHz. A detuned antenna dramatically reduces the link budget and is the most common cause of Sigfox certification failures in production.
GPIO2 and GPIO3 are designated 'Not Connected' on RCZ1 designs. Per the manufacturer datasheet DS_WSSFM10R1AT_REV12, these pads are reserved for zone-variant compatibility and should be left floating on RCZ1 host PCBs. Connecting them risks contention with internal module signals or increased leakage current. Do not assume they are general-purpose GPIO - they are conditional based on the zone variant, not on the user's application.
Estimated: At a typical Sigfox duty cycle of 6 uplinks per hour (well below the 140/day ceiling), average module current is dominated by sleep current. At 3.3 V, even a 2 uA sleep current yields ~57 mAh per year of standby budget. Active TX frames at +14 dBm draw tens of milliamps for hundreds of milliseconds, so a 10 uF ceramic decoupling capacitor close to the VDD pin is required to avoid supply droop. Confirm the battery's internal resistance can source the TX peak, especially for primary-cell designs with high-ESR lithium chemistries.
