WSSFM10R1 Descripción general
A Sigfox module is a pre-certified sub-GHz radio plus protocol-stack module that abstracts the physical and MAC layers of the Sigfox LPWAN so the host MCU only needs to issue AT commands over UART. Sigfox modules sit below the application MCU and above the bare RF transceiver in the connectivity hierarchy (Sigfox module -> sub-GHz LPWAN module -> wireless module -> IoT connectivity IC -> semiconductor). They are favored for asset tracking, smart sensors, smart buttons, and metering endpoints because the radio is pre-tuned and the protocol stack is pre-licensed.
Key features of the WSSFM10R1 include Sigfox-only protocol operation, integrated TCXO for frequency stability, UART command interface, 31-pin SMD land-grid package, and pin-to-pin compatibility across the RCZ1/RCZ2/RCZ3/RCZ4 Wisol Sigfox family per the manufacturer datasheet. The module is built around an OnSemi AX-Sigfox transceiver implementation, which simplifies customer designs by eliminating the discrete RF matching network normally required for Sigfox CE compliance.
The architecture pairs an OnSemi Sigfox modem SoC with a TCXO reference, antenna RF chain, and power-tree filtering, all routed to the host through a UART bridge. Module firmware exposes the AT command set; GPIO2 and GPIO3 are reserved as "Not connected" on RCZ2/RCZ4-compatible variants and unused on RCZ1 SKUs.
Typical applications include Sigfox asset tracking, animal tracking tags, smart metering endpoints, smart city sensors, push-button remote controls, and healthcare wearables. The Wisol WSSFM10R1 is well-suited whenever a low-data-rate, ultra-low-power uplink is required and the deployment region falls inside the RCZ1, RCZ6, or RCZ7 Sigfox coverage zones.
When designing in this part, mount the module on a PCB with a 50-ohm controlled-impedance antenna trace to the chip antenna or external antenna connector, keep the TCXO area clear of thermal gradients, and confirm regional Sigfox zone membership (RCZ1) before committing the BOM. The WSSFM10R1 is also distinguished from the WSSFM10R1AT AT-command variant by its firmware image - both share the same 31-pin SMD footprint.

Aplicaciones típicas
WSSFM10R1 es adecuado para 6 aplicacións: Sigfox Asset Tracking, Animal Tracking Collars, Smart Metering Endpoints, Smart City Environmental Sensors, Smart Button / Wireless Panic Alarm, Healthcare Wearables and Telehealth Patches.
Sigfox Asset Tracking
The Wisol WSSFM10R1 is purpose-built for battery-powered asset tracking tags that need multi-year operational life across European, Middle Eastern, and African supply chains. Its 14 dBm maximum TX setting (the manufacturer-recommended default) plus integrated TCXO give it the link budget needed to deliver uplink frames from inside containers, warehouses, and urban canyons. The on-board MCU removes the need for an external host processor in minimalist tag designs, and the UART host interface keeps the BOM tiny. Compared to cellular LTE-M alternatives, the WSSFM10R1 cuts modem power by an order of magnitude, which directly extends tag battery life in cold-chain and returnable-asset use cases.
Recomendado
Animal Tracking Collars
Livestock and pet tracking collars benefit from the WSSFM10R1's 13.0 x 15.0 x 2.21 mm footprint and Sigfox-only protocol, which together minimize collar bulk and BOM cost. The integrated TCXO holds frequency tolerance during long sleep intervals - critical for collars that wake only a few times per day to upload position pings. According to Wisol and Avnet Asia Sigfox-module catalog data, animal tracking is a flagship application for the WSSFM10R1 family. The module's RCZ1/RCZ6/RCZ7 regional qualification also opens up cattle and wildlife deployments across Europe, India, and Russia on a single SKU.
Recomendado
Smart Metering Endpoints
Water, gas, and heat-meter endpoints need an ultra-low-power uplink that survives a 10-year battery life target - exactly the operational profile of the WSSFM10R1. With RCZ1/RCZ6/RCZ7 Sigfox certification, the module supports meter rollouts across EMEA, India, and Russia. The integrated MCU plus UART host interface lets the meter ASIC push consumption counters directly to the module without an intermediate processor. The 31-pin SMD land-grid layout and pin-to-pin compatibility across the Wisol WSSFM10 family also lets meter OEMs use a single PCB for multiple regional SKUs.
Recomendado
Smart City Environmental Sensors
Air-quality, noise, and waste-bin-level sensors are classic Sigfox smart-city use cases that fit the WSSFM10R1's low-bandwidth uplink profile and the RCZ1 Sigfox network footprint across major European cities. The module's 13.0 x 15.0 mm land-grid module is small enough for retrofit enclosures and streetlight-mounted sensor pods. According to Avnet Asia's Wisol product entry, smart-city deployments are an explicitly targeted use case. The 14 dBm default TX output provides the link margin needed for in-building waste-bin sensors and underground parking CO/NO2 monitors.
Recomendado
Smart Button / Wireless Panic Alarm
Push-button remote controls and panic alarms require a coin-cell-powered Sigfox uplink that fires on a single press, then sleeps for years - a profile that aligns with the WSSFM10R1's UART-driven AT-command interface and ultra-low standby current. The module's small 13.0 x 15.0 mm footprint fits a CR2032 holder, and the integrated TCXO ensures the wake-time uplink reaches the Sigfox base station even after multi-year dormancy. According to Wisol catalog data, the WSSFM10R1 supports smart-button applications including hotel service buttons, industrial E-stops, and elder-care panic pendants.
Recomendado
Healthcare Wearables and Telehealth Patches
Telehealth patches and wearable health monitors that transmit small vital-sign packets (heart-rate, SpO2, fall detection) over a sub-GHz LPWAN benefit from the WSSFM10R1's combination of small footprint, integrated MCU, and integrated Sigfox stack. The RCZ1 regional qualification supports deployments across European telehealth networks, and the pin-to-pin compatibility across the Wisol WSSFM10 family lets a single wearable design ship in RCZ1, RCZ6, and RCZ7 markets without PCB rework. Avnet Asia lists healthcare as an explicit target segment for Wisol Sigfox modules.

Diferenciadores clave
- Multi-region Sigfox certification (RCZ1 + RCZ6 + RCZ7) in a single SKU (frente a WSSFM10R2 (RCZ2 only))
- Pin-to-pin compatibility across the entire WSSFM10 family (frente a WSSFM10R3 / WSSFM10R4)
- AT-command firmware variant available on the same hardware (frente a WSSFM10R1AT)
Notas de diseño
Place the WSSFM10R1 on a PCB with a 50-ohm controlled-impedance antenna feed (CPW or microstrip) leading to either a chip antenna on the same PCB or an external U.FL/MHF antenna connector. The 31-pin SMD land-grid requires a clearance keep-out zone around the antenna feed per the Wisol reference design - typically a 5 mm copper-free area around the antenna trace. Mount decoupling 100 nF + 1 uF directly at the VCC pin with the shortest possible trace length to minimize uplink noise coupling into the TCXO reference.
Do not select the WSSFM10R1 for deployments outside RCZ1, RCZ6, or RCZ7 - this SKU is not certified for Americas (RCZ2/RCZ4) or Japan/Asia-Pacific (RCZ3) Sigfox networks. Confirm the Sigfox network rollout status in your target country before committing to the BOM. According to Wisol datasheet rev. 12, GPIO2 and GPIO3 are reserved as Not Connected on RCZ2/RCZ4-compatible firmware images - leave these pads floating on the PCB to allow cross-region firmware flashing without rework.
Although the WSSFM10R1 is a low-power Sigfox module, the integrated TCXO is sensitive to thermal gradients from nearby heat sources. Route high-current PCB traces (battery-charger FETs, coin-cell boost regulators) at least 5 mm away from the TCXO area to avoid frequency drift and Sigfox uplink frame rejections at the base station. Keep the module's ground plane continuous and stitch with 4-8 vias around the land-grid for thermal and RF return-path integrity.
