FCC Certified Sensor Module: Why the MultiNav Pro+ Sets a New Standard for Builders
RFOXiA Integrated Sensors Module
The Most Complete FCC Certified Sensor Module Available for Makers, Drone Builders, and IoT Engineers
If you've spent any time sourcing sensors for a serious hardware project, you know the frustration. You need motion data, environmental readings, and location awareness — and you end up wiring together five different breakout boards from five different vendors, debugging I2C address conflicts at midnight, and wondering why no one has solved this yet.
RFOXiA has solved it.
The MultiNav Pro+ Sensors Module is a single, compact, FCC certified sensor module that integrates seven professional-grade sensors into a board measuring just 24mm × 18mm. It ships ready to deploy, plays perfectly within the full RFOXiA wireless ecosystem, and costs $39.
This isn't a hobbyist toy. This is production-ready hardware built for builders who care about signal integrity, sensor accuracy, and real-world deployment.
What Makes a Sensor Module Worth Using in 2025
Before we get into the specs, let's be honest about what most sensor breakout boards get wrong:
- Single-purpose boards that force you to stack hardware and manage multiple power rails
- No regulatory certification, meaning you can't legally deploy in a commercial or research context without additional compliance work
- Cheap commodity sensors that drift under temperature change or saturate in real-world conditions
- Poor I2C management that causes address collisions and forces ugly workarounds in firmware
A genuinely useful sensor module for professional work needs to solve all of these problems. The MultiNav Pro+ does.
Seven Sensors. One Board. One I2C Line.
The MultiNav Pro+ Sensors Module includes the following sensor complement:
Motion Sensing
- Accelerometer — 3-axis linear acceleration
- Gyroscope — 3-axis angular rate
- Magnetometer — 3-axis magnetic field (compass heading)
Environmental Sensing
- Temperature — ambient air temperature
- Humidity — relative humidity
- Air Pressure — barometric pressure (also useful for altitude estimation)
- Air Quality — volatile organic compound and outdoor air quality index
Seven sensors. All accessible over a single I2C bus. Each sensor has a dedicated I2C address, so there are zero collision issues and no multiplexer hacks needed.
For a drone builder, this means attitude estimation (accelerometer + gyroscope + magnetometer), altitude hold (barometric pressure), and environmental awareness (temperature, humidity, air quality) — all from one board that weighs almost nothing and takes up almost no space.
For an IoT engineer, this means a single module can anchor an environmental monitoring node with motion detection built in — useful for detecting tampering, vibration events, or platform movement.
The Sensors Under the Hood
RFOXiA didn't build this module around bargain-bin components. Every sensor is sourced from a Tier 1 manufacturer with proven performance in demanding applications:
BMI270 — Bosch Sensortec (Accelerometer & Gyroscope)
The BMI270 is Bosch's flagship IMU for wearables and robotics. It's optimized for always-on operation, features an integrated step detection engine, and delivers 16-bit resolution on both accelerometer and gyroscope axes. It's the same class of sensor used in professional drone flight controllers and high-end wearable devices.
TMAG5273C1QDBVR — Texas Instruments (Magnetometer)
This 3-axis Hall-effect magnetometer from TI is designed for low-power operation and high magnetic field linearity. It's well-suited for compass heading applications, gear tooth counting, and proximity detection in noisy electromagnetic environments.
LPS22HHTR — STMicroelectronics (Air Pressure)
The LPS22HH is ST's waterproof MEMS pressure sensor — accurate, low-noise, and fast. It reads absolute pressure and temperature simultaneously, making it useful for both weather monitoring and drone altitude estimation without a dedicated altimeter.
MVH4003D — MEMSVision (Humidity & Temperature)
The MVH4003D is a digital humidity and temperature sensor with high accuracy and fast response time. It handles condensing environments and delivers reliable readings across a wide operating temperature range.
ZMOD4510AI4R — RENESAS (Air Quality)
The ZMOD4510 is RENESAS's outdoor air quality sensor, specifically designed for detecting ozone and nitrogen dioxide — the primary markers of urban outdoor air pollution. This isn't a generic VOC sensor repurposed for outdoor use. It's engineered for outdoor deployment, which makes it directly relevant to the RFOXiA data network's environmental monitoring applications.
This component selection alone separates the MultiNav Pro+ from generic sensor breakout boards. These are the parts engineers choose when they need data they can actually trust.
Precision Motion and Environmental Sensing — Built for Real Deployments
The MultiNav Pro+ isn't designed for a lab bench. It's designed for the real world — where drones vibrate, temperatures swing, and environmental conditions change faster than a 1-minute API refresh can capture.
The motion sensing stack (BMI270 + TMAG5273) delivers the kind of responsive, high-frequency attitude data that professional drone and robotics applications demand. When you're flying at speed or running a ground robot over uneven terrain, you need your IMU data to be current, not lagging.
The environmental sensing stack (LPS22HH + MVH4003D + ZMOD4510) delivers hyper-local readings that no weather API can match. A rooftop weather station three kilometers away doesn't tell you what the air quality is at ground level on your street right now. Your MultiNav Pro+ node does.
This combination — motion plus environment — is what makes the MultiNav Pro+ genuinely versatile across a wide range of professional applications.
Efficient I2C Communication — No Address Conflicts, No Multiplexers
One of the most underappreciated design decisions in the MultiNav Pro+ is how RFOXiA handled the I2C bus.
When you try to wire multiple sensor breakout boards together yourself, I2C address management becomes a real problem. Many popular sensors share default addresses. You end up needing I2C multiplexers, address-swapping jumpers, or software workarounds that add latency and complexity.
With the MultiNav Pro+, every sensor has been assigned a dedicated, non-conflicting I2C address. All seven sensors share a single I2C line cleanly. There's no multiplexer. There's no firmware gymnastics. You wire one SDA line and one SCL line, scan the bus, and all seven sensors show up exactly where they should be.
For developers integrating this module into a larger system — especially one already managing a BLE module, GNSS module, and power management — this simplicity is genuinely valuable. Clean buses mean clean code. Clean code means fewer bugs and faster development cycles.
Compact Design Built for Space-Constrained Platforms
The MultiNav Pro+ Sensors Module measures 24mm × 18mm.
To put that in perspective: that's smaller than a standard postage stamp. At that size, you can mount this module almost anywhere — on a drone arm, inside a wearable enclosure, on the underside of a research UAV, inside a compact field deployment unit.
Small form factor hardware typically comes with compromises — fewer sensors, lower accuracy, or cheaper components. The MultiNav Pro+ doesn't make those compromises. The miniaturization is achieved through careful PCB layout and component selection, not by cutting corners on what's actually on the board.
For drone builders specifically, mass and volume budget are real constraints. Every gram matters. Every cubic centimeter matters. A module that delivers seven sensors in 24mm × 18mm at minimal weight is a meaningful engineering achievement.
Real-Time Environmental Data You Can Actually Use
Real-time is a term that gets thrown around loosely. With the MultiNav Pro+, it means what it says.
All seven sensors stream live data over the I2C bus continuously. When paired with the RFOXiA BLE Module and the RFOXiA Connect mobile app, you can see live readings from all seven sensors directly on your phone screen — temperature, humidity, pressure, air quality, and full motion vector data — with no perceptible lag.
This has direct practical implications:
For drone operators: You can monitor atmospheric conditions during flight — useful for agricultural spraying, where temperature and humidity affect droplet drift, and for long-range operations where pressure changes indicate altitude shifts.
For field researchers: You have a portable, self-contained environmental data logger that doesn't require cellular connectivity to stream data to your phone. The BLE link handles it all locally.
For data network contributors: The Sensors Module is the core hardware node for the RFOXiA data network. Deploy it outdoors with GNSS validation, and your verified environmental data earns you daily rewards. The ZMOD4510 outdoor air quality sensor is specifically relevant here — it provides the kind of localized outdoor AQI data that enterprise data buyers actually want.

FCC Certification — Why It Matters More Than You Think
The MultiNav Pro+ Sensors Module is FCC certified.
For many makers, FCC certification sounds like a bureaucratic checkbox. In practice, it's one of the most important things to look for when choosing hardware for serious projects.
Why FCC certification matters:
Legal deployment — You can legally deploy FCC certified hardware in the United States without additional compliance work. This matters for commercial deployments, research grants, and anything touching regulated industries.
Distributor qualification — Major distributors including DigiKey, Mouser, and Newark require FCC certification before listing hardware. Certified hardware signals that RFOXiA is building to professional standards.
RF signal integrity — The FCC certification process validates that the module doesn't emit interference that would corrupt other devices' signals. In a multi-module system (BLE + GNSS + Sensors), this is critical. All RFOXiA modules are certified to coexist without mutual interference.
Enterprise and institutional procurement — If you're deploying hardware for a university, municipal program, or commercial operation, your procurement office will ask about FCC certification. With RFOXiA, the answer is yes.
The fact that RFOXiA has achieved FCC certification across their entire product line — BLE Module, GNSS Module, Sensors Module, and Power/Program Kit — is a significant differentiator. Most maker-tier hardware skips this step entirely.
The MultiNav Pro+ is a genuine FCC certified sensor module designed for the real world, not just the workbench.
Endless Applications Across Serious Verticals
The MultiNav Pro+ Sensors Module is not optimized for a single use case. Its combination of motion and environmental sensing gives it genuine utility across a wide range of demanding applications:
