RC1692HP-SIG Overview
A Sigfox transceiver module is a wireless radio subsystem that bundles the RF front-end, a microcontroller running the embedded Sigfox protocol stack, and regulatory-certified firmware into a single surface-mount device. Sigfox is a low-power wide-area network (LPWAN) protocol used for ultra-narrow-band IoT telemetry in the sub-1 GHz ISM bands. The RC1692HP-SIG belongs to the Radiocrafts RC1692 family of compact Sigfox modules, which are FCC- and ACMA-pre-certified, allowing end-product designers to skip most RF compliance testing.
Key features include an integrated 25 dBm power amplifier for long-range links, on-board antenna matching network with U.FL RF connector option (depending on variant), built-in AES-128 hardware encryption, and a UART host interface for AT-command configuration. The module is pre-loaded with Sigfox library and is shipped with a unique device ID and PAC code for network registration. Low-power sleep modes reduce current consumption to microamp levels for battery-powered deployments.
The RC1692HP-SIG uses a Silicon Labs sub-GHz transceiver IC paired with an embedded protocol controller running the Sigfox stack. Internal TCXO provides frequency stability across industrial temperature ranges. The 12.7 x 25.4 x 3.3 mm footprint is a standardized land pattern used across the Radiocrafts RC16xx family, allowing PCB reuse across regional variants (EU868, US915, AU915).
Typical applications include wireless IoT sensor nodes for asset tracking, environmental monitoring, smart agriculture soil/moisture telemetry, smart metering backhaul, and industrial equipment monitoring in factories. The 25 dBm output power extends link budget to several kilometers in line-of-sight conditions, making it suitable for rural and wide-area deployments.
When designing with this module, host firmware must initialize the UART interface at the correct baud rate and load the Sigfox PAC during onboarding. Engineers should follow the reference layout in the RC1692HP-SIG user manual for RF trace impedance and decoupling to preserve FCC/ACMA certification status.

Typical Applications
RC1692HP-SIG is suitable for 6 applications: Wireless IoT Sensor Nodes (Sigfox LPWAN), Asset Tracking & Logistics, Smart Agriculture Soil and Environmental Telemetry, Smart Metering Backhaul (Water/Gas/Electricity), Industrial Equipment Monitoring, Smart City Infrastructure (Street Lighting, Waste Bins).
Wireless IoT Sensor Nodes (Sigfox LPWAN)
The RC1692HP-SIG's 25 dBm output and FCC pre-certification make it well suited for ultra-narrow-band sensor telemetry in the Sigfox LPWAN. With 600 bps uplink in the 902-928 MHz ISM band and an integrated AES-128 cipher, an end node can stream temperature, level, or status readings every few minutes across several kilometers in line-of-sight conditions. The 2.8-3.6 V supply and UART host interface simplify integration with low-cost 8-bit MCUs, while deep-sleep currents in the microamp range support multi-year battery life on 2x AA cells when transmissions are scheduled.
Recommended
Asset Tracking & Logistics
Asset-tracking applications leverage the RC1692HP-SIG's long-range +25 dBm link to report GPS or location-tagged beacons back to a Sigfox cloud backend. The module's 3.3 V rail fits cleanly with battery-powered GPS+Sigfox designs, and the standardized 12.7 x 25.4 mm footprint allows reuse across container-, pallet-, and equipment-tracking SKUs. With OTA-configurable PAC codes and downlink support, operators can remotely reconfigure tags when shipment ownership changes, while the 36 mA RX current keeps average drain low for infrequent acknowledgments during border crossings.
Recommended
Smart Agriculture Soil and Environmental Telemetry
In remote agriculture deployments where cellular coverage is unavailable, the RC1692HP-SIG's 25 dBm output extends Sigfox coverage to fields, vineyards, and orchards far from base stations. The -30 to +85 C industrial temperature range handles greenhouse and outdoor cabinet environments, while the module's UART interface connects directly to soil-moisture and microclimate sensors via a low-power host MCU. With FCC/ACMA pre-certification, integrators can ship finished agricultural sensor nodes to US/AU markets without RF lab retesting.
Recommended
Smart Metering Backhaul (Water/Gas/Electricity)
Utility metering applications benefit from the RC1692HP-SIG's combination of long-range link budget and ultra-low sleep current. A typical water meter reports usage once per day, transmitting a brief payload at +25 dBm that Sigfox base stations receive kilometers away. The module's hardware AES-128 protects billing data in transit, and the 3.3 V supply shares a regulator with metrology SoCs. The standardized 12.7 x 25.4 mm footprint allows meter manufacturers to drop in regional variants (EU868, US915, AU915) without redesigning the host PCB.
Recommended
Industrial Equipment Monitoring
Factory-floor monitoring of pumps, motors, and valves over Sigfox uses the RC1692HP-SIG to relay vibration, temperature, and run-time data to cloud dashboards. The module's industrial -30 to +85 C operating range tolerates enclosure environments near motors, and the 25 dBm link budget means a single Sigfox base station can cover an entire facility. UART-AT command framing lets legacy PLCs and embedded controllers push state events to the module, while downlink enables remote commands to shut down or restart equipment.
Recommended
Smart City Infrastructure (Street Lighting, Waste Bins)
Smart-city deployments such as street-lighting controllers and waste-level sensors use the RC1692HP-SIG to deliver citywide coverage from existing Sigfox antennas. The 25 dBm output closes the link from below-ground bin sensors or shielded luminaire housings, and the module's compact 12.7 x 25.4 mm area fits inside IP65 enclosures. ACMA pre-certification supports Australian deployments; FCC supports US rollouts; both leverage the same SKU, reducing inventory complexity for municipal integrators.

Key Differentiators
- High-power +25 dBm output for long-range Sigfox (vs RC1692-SIG)

- Sensor-enabled variant for environmental telemetry (vs RC1692HP-SSM)
Design Notes
The RC1692HP-SIG draws peak transmit currents above 300 mA when bursting at 25 dBm. Per the Radiocrafts datasheet, place a 10 uF bulk ceramic or tantalum capacitor as close as possible to the VDD pin, plus a 100 nF decoupling capacitor in parallel to handle transients. A 3.3 V LDO with at least 500 mA rating (or a switching regulator with similar capability) is recommended; under-rated supplies cause brown-out resets during TX.
Follow the reference PCB layout in the RC1692HP-SIG datasheet to preserve FCC/ACMA pre-certification. The 50-ohm RF trace from the castellation RF pad to the U.FL connector must be impedance-controlled (grounded coplanar waveguide with continuous ground stitching vias). Avoid routing noisy digital signals under the RF section and keep the antenna pigtail shorter than 50 mm to limit loss.
Do not exceed the 3.6 V absolute maximum supply rating - even brief transients from USB plug-in events can latch the module. Add a TVS diode or schottky clamp on VDD for hot-plugged hosts. Also note that the Sigfox PAC and device ID are factory-programmed and cannot be re-flashed; mixing modules across fleets requires re-registering each on the Sigfox backend, per the manufacturer's onboarding guide.
Compliance Information
RoHS compliant per Radiocrafts product page (JLCPCB listing). FCC and ACMA pre-certified for 902-928 MHz ISM band. Not AEC-Q100 qualified; the module is intended for industrial/commercial IoT, not automotive.
