All in One Sensor Module IoT: The MultiNav Pro+ Sensors Module
RFOXiA Integrated Sensors Module
The Ultimate All in One Sensor Module IoT Developers Have Been Waiting For
Building a connected device that needs to understand its environment — and its own motion — usually means sourcing five, six, or seven separate components, writing individual drivers for each, routing a tangled web of connections across your PCB, and debugging integration issues for weeks before your actual application logic even runs. For drone builders, robotics engineers, field researchers, and IoT developers, this process is both time-consuming and expensive.
The MultiNav Pro+ Sensors Module from RFOXiA changes that completely.
This is a single, compact, FCC-certified module that integrates seven professional-grade sensors onto a 24mm × 18mm board — delivering complete environmental and motion sensing through a single I2C line. It is the all in one sensor module IoT projects have needed: no compromises, no compatibility headaches, and no bloated BOM.
Whether you are flying a precision drone over agricultural land, building a smart city air quality node, developing a wearable health monitor, or deploying a remote environmental research station, the MultiNav Pro+ Sensors Module gives you every data point you need in one board, available right now for $39.
What Makes This Module Different
Most sensor breakout boards give you one sensor. Maybe two. The MultiNav Pro+ Sensors Module gives you seven — carefully selected from leading semiconductor manufacturers — all unified under a single I2C bus with dedicated addresses per device.
That single architectural decision eliminates almost all the integration friction that developers normally face. No SPI/I2C conflicts. No competing interrupt lines. No library incompatibilities. You connect one cable, initialize seven sensors, and start reading data.
This is the design philosophy that separates a professional module from a hobby breakout. RFOXiA engineered this board for real applications — where reliability, data accuracy, and development speed all matter.
The Seven Sensors: A Complete Picture
Each sensor on the MultiNav Pro+ Sensors Module was selected because it is the best in its class at this price point. Here is what you get:
Motion Sensing
Accelerometer & Gyroscope — BMI270 from Bosch Sensortec
The BMI270 is a professional inertial measurement unit used in flagship smartphones, professional drones, and advanced robotics platforms. It delivers precise 6-axis motion data — three axes of acceleration and three axes of rotation — with ultra-low noise performance and advanced power management. For drone stabilization, gesture recognition, fall detection, or navigation dead-reckoning, the BMI270 is one of the most trusted IMU chips in the industry.
Magnetometer — TMAG5273C1QDBVR from Texas Instruments
The Texas Instruments TMAG5273 is a 3D Hall-effect magnetic sensor with high sensitivity and a wide dynamic range. Combined with the BMI270, it completes the full 9-axis IMU stack — giving your application absolute heading reference that gyroscopes and accelerometers alone cannot provide. This is essential for compass-based navigation, drone heading lock, and any application where orientation in the real world matters.
Environmental Sensing
Air Pressure — LPS22HHTR from STMicroelectronics
STMicroelectronics' LPS22HH is a high-accuracy MEMS pressure sensor capable of detecting altitude changes as small as 10 centimeters. It is used in professional drones for altitude hold, in weather stations for barometric pressure monitoring, and in industrial equipment for pressure-based process control. The LPS22HH offers both absolute pressure and temperature output, giving you a highly reliable altitude reference that complements GNSS data in GPS-denied environments.
Humidity & Temperature — MVH4003D from MEMSVision
The MEMSVision MVH4003D delivers combined relative humidity and temperature sensing in a compact package with excellent long-term stability. Temperature and humidity data are foundational to agricultural monitoring, HVAC control, food storage logistics, indoor air quality systems, and weather data networks. At the data resolution this sensor provides, your application can detect micro-climate variations that weather station APIs simply cannot resolve.
Air Quality — ZMOD4510AI4R from RENESAS
The RENESAS ZMOD4510 is an outdoor air quality sensor specifically designed to detect ozone (O₃) and nitrogen dioxide (NO₂) — two of the most significant urban air pollutants. Unlike generic VOC sensors that measure everything indiscriminately, the ZMOD4510 is optimized for outdoor deployment and provides an EPA-aligned Air Quality Index (AQI) output directly usable in environmental applications. For smart city developers, environmental researchers, and RFOXiA's own data monetization network, this sensor delivers the kind of verified, meaningful data that enterprise buyers pay for.
Sensor Specifications at a Glance
| Sensor | IC | Manufacturer | Function |
|---|---|---|---|
| Accelerometer & Gyroscope | BMI270 | Bosch Sensortec | 6-axis inertial motion |
| Magnetometer | TMAG5273C1QDBVR | Texas Instruments | 3D magnetic field / heading |
| Air Pressure | LPS22HHTR | STMicroelectronics | Barometric pressure / altitude |
| Humidity & Temperature | MVH4003D | MEMSVision | Environmental climate |
| Air Quality | ZMOD4510AI4R | RENESAS | Outdoor AQI / ozone / NO₂ |
I2C Architecture: Simplicity That Scales
One of the most significant engineering decisions on this board is the I2C bus architecture. All seven sensors share a single I2C line, each assigned a unique device address. This means:
- One cable from your microcontroller or host board to the Sensors Module
- No bus conflicts — each sensor responds only to its own address
- No data collisions — the I2C protocol manages sequential reads cleanly
- Simpler firmware — a single bus initialization handles all devices
- Easier PCB routing — no parallel SPI connections or dedicated chip selects
For developers building with Arduino, STM32, ESP32, Nordic nRF series, or Raspberry Pi, this architecture means your sensor integration is a few dozen lines of code — not a multi-day debugging exercise.
Compact Form Factor: 24mm × 18mm
The MultiNav Pro+ Sensors Module measures just 24mm × 18mm — smaller than a postage stamp. At this size, it integrates cleanly into drones where every gram matters, wearable devices where space is at an absolute premium, compact IoT sensor nodes, and portable field instruments.
Despite the compact footprint, the board maintains proper component spacing for RF sensitivity on the air quality sensor, adequate thermal isolation between temperature-sensitive components, and robust connection pads for reliable soldering and connector attachment.
This is professional PCB design — the kind that only comes from a team that has built and shipped hardware through multiple product generations.
Real-Time Environmental Data: What It Actually Means
The phrase "real-time data" is overused in marketing. Here is what it specifically means for the MultiNav Pro+ Sensors Module:
- Pressure and altitude updates fast enough to support active drone altitude hold loops
- IMU data at rates appropriate for flight controller feedback and stabilization
- Air quality readings that update continuously, not on a slow polling interval
- Temperature and humidity that reflect actual ambient conditions, not lagging averages
For developers building applications where conditions change fast — drone flight, vehicle tracking, industrial process monitoring — the speed and accuracy of sensor data directly determines application performance. The MultiNav Pro+ Sensors Module is designed for these demanding real-time use cases.
When you connect the Sensors Module to the RFOXiA Connect app via the BLE Module, all of this data streams live to your mobile device and is displayed on a clean dashboard — no custom firmware required to get started.
Applications: What You Can Actually Build
The range of applications for a true all in one sensor module IoT platform like this is remarkably broad. Here are the core use cases where developers are deploying the MultiNav Pro+ Sensors Module today:
Professional Drone Platforms
Combine pressure-based altitude hold with 9-axis IMU stabilization and live air quality monitoring. Know your altitude, attitude, and the air you are flying through — all from a single module that adds less than 5 grams to your build.
Environmental Research and Field Stations
Deploy sensor nodes in remote locations to collect hyper-local environmental data. The combination of temperature, humidity, pressure, and calibrated air quality creates a complete micro-meteorological station in a 24mm × 18mm package.
Smart City Infrastructure
Air quality monitoring at street level, neighborhood by neighborhood, block by block. The RENESAS ZMOD4510 provides EPA-aligned AQI data that is directly comparable to regulatory standards — making it appropriate for reporting and research, not just indication.
Agricultural Technology
Micro-climate monitoring across field areas for precision irrigation decisions, frost prediction, and crop health management. Environmental gradients that satellite data cannot resolve become visible with ground-truth sensor networks.
Robotics and Autonomous Systems
Full 9-axis orientation sensing enables accurate heading, tilt compensation, and dead-reckoning navigation. For ground robots, the magnetometer enables compass heading even when GPS is unavailable.
Wearable and Health Devices
Temperature, humidity, pressure, and air quality in a wearable package — for environmental health applications, occupational safety monitoring, or personal air quality awareness.
