LSM110A Overview
A LoRa (Long Range) radio module is a wireless transceiver sub-system built on Semtech's chirp-spread-spectrum modulation that delivers kilometer-scale communication at very low current consumption, ideal for battery-powered IoT endpoints. Sigfox is a complementary ultra-narrowband LPWAN technology operated by a global network carrier that uses the same sub-1 GHz ISM bands but provides lower bit-rate, longer-range, ultra-low-power messaging. By integrating both protocols, hybrid modules such as the LSM110A let designers choose the optimal transport per packet, geographic region, or application without redesigning hardware.
Key features include a high-interference-immunity spread-spectrum physical layer, support for AT and API command interfaces, and FCC pre-certification. The 14.0 x 15.0 mm LCC-34 footprint makes it the smallest LoRa+Sigfox hybrid module in the SJIT portfolio and one of the smallest on the market, allowing product miniaturization for asset trackers and wearable sensor nodes.
Architecturally, the STM32WL SoC integrates the radio, modem, and microcontroller into one die, reducing BOM count and PCB area. The LCC-34 package's exposed ground pad improves thermal performance and RF grounding for consistent radiated performance across production lots.
Typical applications include Sigfox/LoRaWAN asset tracking, smart agriculture soil and livestock sensors, smart-metering endpoints, industrial SCADA monitoring, and GPS-free indoor/outdoor positioning reference nodes. The hybrid protocol support means a single SKU can ship to the US, Australia, and parts of Asia with no firmware region-locking.
When designing with the LSM110A, ensure the antenna matching network is tuned for the specific antenna chosen (chip, trace, or external SMA) and that the host MCU's UART levels match the module's 3.3 V CMOS interface. Power-rail decoupling requires at least a 10 uF bulk plus a 100 nF ceramic placed within 5 mm of the module's VDD pins.

Typical Applications
LSM110A is suitable for 6 applications: Hybrid LPWAN Asset Tracking, Smart Agriculture Soil and Livestock Sensors, Smart Metering Endpoints (Water/Gas), Industrial SCADA and Tank-Level Monitoring, Smart City Infrastructure Nodes, GPS-Free Indoor/Outdoor Positioning Reference.
Hybrid LPWAN Asset Tracking
The LSM110A's combined LoRa and Sigfox support makes it ideal for asset-tracking devices that need to roam between LoRaWAN private networks and Sigfox public infrastructure without firmware swaps. With 22 dBm output power and STM32WL integration, the module can transmit GPS-fix packets over kilometers while sipping battery, enabling multi-year tracker lifetimes on a single Li-ion cell. The LCC-34 footprint lets engineers shrink the tracker PCB to fit inside small enclosures used for tool, pallet, and container tracking across logistics operations in the US, Australia, and Asia.

Smart Agriculture Soil and Livestock Sensors
LoRaWAN's km-scale link budget and Sigfox's ultra-low-power downlink make the LSM110A well suited to remote soil-moisture probes, irrigation valve controllers, and livestock collars that must work for years on a battery. With 22 dBm Tx power and the STM32WL's low sleep current, a 2.4 Ah primary cell can power a soil sensor reporting hourly for 5+ years in zone RC4 deployments. The LCC-34 castellation style is rugged enough for outdoor enclosures, and the FCC pre-certification accelerates farm-equipment OEM compliance.
Recommended
Smart Metering Endpoints (Water/Gas)
Utility metering requires a radio module that can deliver reliable daily uplinks from inside metal cabinets, basements, or buried pits - exactly the harsh RF environment the LSM110A's 22 dBm chirp-spread-spectrum link is designed to overcome. Because the STM32WL integrates both MCU and radio, the meter BOM drops to a sensor, a battery, and the module, reducing manufacturing cost per endpoint. Sigfox RC2/RC4 coverage gives US/AU/Asia-Pacific utilities a public-network option without spinning up a LoRaWAN gateway.
Recommended
Industrial SCADA and Tank-Level Monitoring
Industrial sites need wireless monitoring of tank levels, valve states, and machine health where pulling cable is impractical. The LSM110A's STM32WL can read analog/digital sensor inputs and transmit via either LoRaWAN or Sigfox from the same firmware image, simplifying multi-vendor deployments. With 22 dBm output and high interference immunity from chirp-spread-spectrum, the module maintains links next to VFDs, motors, and switching power supplies that would swamp narrower-band radios.
Recommended
Smart City Infrastructure Nodes
Street-lighting controllers, parking sensors, waste-bin level sensors, and environmental monitors deployed across a city need a single radio SKU that can hit both LoRaWAN and Sigfox backends - the LSM110A's hybrid protocol stack serves both. At 14 x 15 mm, the module fits inside compact city-furniture enclosures, and the 22 dBm Tx output covers multi-block distances from a single gateway. Pre-certified FCC ID reduces per-product type-approval cost when deploying many SKUs.
Recommended
GPS-Free Indoor/Outdoor Positioning Reference
Because the LSM110A supports both LoRaWAN TDOA/ RSSI fingerprinting and Sigfox Atlas positioning services, it can act as a transmit-only beacon for indoor and outdoor asset positioning without GPS. At 22 dBm the beacon is detectable through multi-wall propagation, and the STM32WL allows on-module logic to throttle transmit rate based on motion sensors. The LCC-34 footprint simplifies integration into badges, wristbands, and small equipment tags.

Key Differentiators
- Hybrid LoRa + Sigfox in a single 14 x 15 mm module (vs SFM10R4 (Sigfox only, same SJIT family))
- STM32WL SoC integration eliminates external MCU (vs Older SX1276 + external MCU modules)
- FCC pre-certification under 2BEK7LSM110A (vs Non-certified LoRa modules)
Design Notes
Place at least a 10 uF X5R bulk ceramic plus a 100 nF X7R decoupling capacitor within 5 mm of the module's VDD pins; the STM32WL radio is sensitive to VDD ripple during Tx bursts. Keep the ground-return path under the LCC-34 ground pad stitched with a 4 x 4 via array to the inner ground plane to maximize RF grounding and thermal dissipation.
Route the antenna feed line as a 50 ohm coplanar waveguide with ground on both sides, kept as short as possible and free of splits. Do not run digital signals under the antenna feed on the same layer; if the board stackup forces overlap, use stitching vias to isolate the noisy layers. A keep-out zone of at least 5 mm around the antenna pad is recommended.
Do not apply power to the LSM110A from a logic-level GPIO before the host's 3.3 V rail is fully stable; the module's power-on-reset behavior expects VDD to ramp monotonically. Also avoid loading firmware over UART while the host MCU's bootloader is active; bring RESET high for at least 100 ms before issuing AT commands for a clean session.
Compliance Information
RoHS compliance per JLCPCB listing (C9900074282). FCC pre-certified under FCC ID 2BEK7LSM110A for US deployments; regional certifications (RC2/RC4 Sigfox) documented at partners.sigfox.com/products/lsm110a. AEC-Q100 not applicable - this is an RF module, not an automotive-grade IC.
