WS2118-00 Overview
A multi-protocol RF transceiver module is a small surface-mount assembly that combines one or more radio ICs, matching networks, crystal references, and (typically) an antenna interface into a single certified-or-module-level-tested building block. By integrating the BlueNRG-1 and S2-LP radios, the WS2118-00 belongs to the hierarchy: RF transceiver module -> wireless connectivity module -> IoT building block -> embedded electronic component, and lets designers skip discrete RF matching and regulatory pre-compliance work.
Key features include BLE 4.2 stack support on the BlueNRG-1 core, Sigfox RC1/RC2/RC3/RC4 zone coverage on the S2-LP core, integrated balun for both radios, an internal temperature sensor, hardware watchdog, and a reset pin accessible to the host MCU. The module operates from a single 3.3 V supply rail typical for IoT nodes and exposes UART/SPI host interfaces for firmware flashing and command-mode control.
At the architecture level, the BlueNRG-1 (ARM Cortex-M0 + BLE 4.2 radio) handles BLE link-layer and upper-stack duties, while the S2-LP provides long-range, ultra-low-power sub-1GHz Sigfox connectivity. The two radios share the host bus but use separate RF chains, which simplifies antenna design via the single U.FL port and supports coexistence through firmware timing on the host controller.
Typical applications include Sigfox+BLE asset trackers, IoT sensor nodes that need both BLE provisioning and long-range Sigfox uplink, smart-metering endpoints, and industrial wireless telemetry. The dual-radio combination is particularly attractive for devices that need smartphone-based commissioning plus wide-area network uplink.
When designing with this module, plan antenna placement carefully: the U.FL connector requires a 50 ohm trace or external antenna, and regulatory certification is the integrator's responsibility for the final host product. Decoupling capacitors near the host-side supply pins are recommended.

Typical Applications
WS2118-00 is suitable for 6 applications: Sigfox + BLE Asset Tracker, Industrial Wireless Telemetry Node, Smart Metering Endpoints, IoT Environmental Sensor, Smart Home / Building Automation Bridge, Connected Healthcare Wearable.
Sigfox + BLE Asset Tracker
The WS2118-00 fits Sigfox + BLE asset tracking because it integrates both radios on one LCC-36 footprint: the ST S2-LP delivers long-range Sigfox uplink across RC1-RC4 zones (868-923 MHz) while the BlueNRG-1 provides BLE 4.2 for smartphone commissioning and short-range telemetry. On-module resources such as the integrated balun, watchdog, and temperature sensor let designers drop the module onto a small battery-powered PCB without external RF matching. Designers can duty-cycle both radios from firmware to extend battery life across multi-year deployments in logistics and cold-chain visibility use cases.
Recommended
Industrial Wireless Telemetry Node
For industrial wireless telemetry, the WS2118-00 provides a dual-radio path that combines local BLE diagnostics with wide-area Sigfox uplink, eliminating the need for two separate wireless modules. The LCC-36 surface-mount package and U.FL antenna connector simplify mechanical integration in sealed enclosures, and the integrated balun removes discrete RF components that would otherwise complicate EMC compliance. The on-module watchdog and reset function improve robustness in electrically noisy factory environments where supervisory reset is essential.
Recommended
Smart Metering Endpoints
Smart-metering endpoints benefit from the WS2118-00's Sigfox uplink for transmitting periodic consumption data over kilometers of range and its BLE 4.2 radio for installer commissioning and on-site diagnostics. The module's sub-1GHz coverage of 868-923 MHz aligns with European 868 MHz and North American 915 MHz ISM/Sigfox zones, so a single SKU can serve multiple regions after firmware reconfiguration. Designers gain the integrated temperature sensor for compensating meter readings and the watchdog for unattended outdoor deployments.
Recommended
IoT Environmental Sensor
IoT environmental sensors use the WS2118-00 to publish readings over both Sigfox (long range, low payload) and BLE (smartphone retrieval). The module's UART/SPI host interface connects directly to a low-power sensor host MCU, while the integrated balun and reset function shrink the BOM to module + MCU + battery + sensor. The built-in temperature sensor can serve as a fallback reading when no external sensor is connected, useful for low-cost SKUs.
Recommended
Smart Home / Building Automation Bridge
The WS2118-00 acts as a smart-home and building-automation bridge by combining BLE 4.2 (for local smartphone control and beacon-style presence detection) with Sigfox (for cloud uplink where Wi-Fi is unavailable). The LCC-36 module mounts directly on the bridge PCB behind a U.FL-fed patch or whip antenna, simplifying mechanical design versus discrete dual-radio layouts. Host firmware can use the on-module watchdog to recover from mains-side brownouts common in building-control enclosures.
Recommended
Connected Healthcare Wearable
Connected healthcare wearables leverage the WS2118-00's BLE 4.2 link for pairing with a phone-based companion app and the Sigfox link for out-of-range location pings during emergency events. The module's small LCC-36 footprint fits wrist-worn enclosures, while the integrated temperature sensor can supplement body-temperature readings when paired with a clinical-grade external sensor. Low duty-cycle firmware on the S2-LP sub-1GHz side preserves battery life across multi-day wear cycles.

Key Differentiators
- Dual-radio (BLE 4.2 + Sigfox) in a single LCC-36 module (vs Generic single-protocol BLE module)
- Integrated balun, watchdog, and temperature sensor (vs Discrete dual-radio designs with external balun and reset)
- U.FL antenna connector for flexible antenna selection (vs Modules with chip antenna only)
Design Notes
Place the WS2118-00 module at the edge of the host PCB with the U.FL connector facing the board edge. Keep the area directly under the U.FL connector free of ground pour and signal traces to avoid degrading the antenna radiation pattern. A 50 ohm controlled-impedance trace is not required because the U.FL pigtail handles the RF path, but keep the carrier-board ground plane intact under the rest of the module.
Decouple the WS2118-00 supply pins with at least a 10 uF bulk capacitor and a 100 nF ceramic capacitor placed within 5 mm of the module pads. The BlueNRG-1 and S2-LP radio bursts draw sharp current pulses during transmission, and insufficient decoupling can cause TX power droop and reduced link margin. Add a ferrite bead if the host 3.3 V rail shares a noisy switching converter.
Do not assume the WS2118-00 carries pre-certified regulatory approvals for every region. Confirm with the Jorjin datasheet whether the module is FCC, IC, ETSI, or Telec certified, and budget integrator-side EMC testing for the final host product. Avoid routing high-speed digital signals (SPI clock, parallel buses) directly under the module's RF section to minimize coupling into the antenna path.
